Changelog#

1.9.6 (core) / 0.25.6 (libraries)#

New#

  • Updated cronitor pin to allow versions >= 5.0.1 to enable use of DayOfWeek as 7. Cronitor 4.0.0 is still disallowed. (Thanks, @joshuataylor!)
  • Added flag checkDbReadyInitContainer to optionally disable db check initContainer.
  • [ui] Added Google Drive icon for kind tags. (Thanks, @dragos-pop!)
  • [ui] Renamed the run lineage sidebar on the Run details page to Re-executions.
  • [ui] Sensors and schedules that appear in the Runs page are now clickable.
  • [ui] Runs targeting assets now show more of the assets in the Runs page.
  • [dagster-airbyte] The destination type for an Airbyte asset is now added as a kind tag for display in the UI.
  • [dagster-gcp] DataprocResource now receives an optional parameter labels to be attached to Dataproc clusters. (Thanks, @thiagoazcampos!)
  • [dagster-k8s] Added a checkDbReadyInitContainer flag to the Dagster Helm chart to allow disabling the default init container behavior. (Thanks, @easontm!)
  • [dagster-k8s] K8s pod logs are now logged when a pod fails. (Thanks, @apetryla!)
  • [dagster-sigma] Introduced build_materialize_workbook_assets_definition which can be used to build assets that run materialize schedules for a Sigma workbook.
  • [dagster-snowflake] SnowflakeResource and SnowflakeIOManager both accept additional_snowflake_connection_args config. This dictionary of arguments will be passed to the snowflake.connector.connect method. This config will be ignored if you are using the sqlalchemy connector.
  • [helm] Added the ability to set user-deployments labels on k8s deployments as well as pods.

Bugfixes#

  • Assets with self dependencies and BackfillPolicy are now evaluated correctly during backfills. Self dependent assets no longer result in serial partition submissions or disregarded upstream dependencies.
  • Previously, the freshness check sensor would not re-evaluate freshness checks if an in-flight run was planning on evaluating that check. Now, the freshness check sensor will kick off an independent run of the check, even if there's already an in flight run, as long as the freshness check can potentially fail.
  • Previously, if the freshness check was in a failing state, the sensor would wait for a run to update the freshness check before re-evaluating. Now, if there's a materialization later than the last evaluation of the freshness check and no planned evaluation, we will re-evaluate the freshness check automatically.
  • [ui] Fixed run log streaming for runs with a large volume of logs.
  • [ui] Fixed a bug in the Backfill Preview where a loading spinner would spin forever if an asset had no valid partitions targeted by the backfill.
  • [dagster-aws] PipesCloudWatchMessageReader correctly identifies streams which are not ready yet and doesn't fail on ThrottlingException. (Thanks, @jenkoian!)
  • [dagster-fivetran] Column metadata can now be fetched for Fivetran assets using FivetranWorkspace.sync_and_poll(...).fetch_column_metadata().
  • [dagster-k8s] The k8s client now waits for the main container to be ready instead of only waiting for sidecar init containers. (Thanks, @OrenLederman!)

Documentation#

  • Fixed a typo in the dlt_assets API docs. (Thanks, @zilto!)

1.9.5 (core) / 0.25.5 (libraries)#

New#

  • The automatic run retry daemon has been updated so that there is a single source of truth for if a run will be retried and if the retry has been launched. Tags are now added to run at failure time indicating if the run will be retried by the automatic retry system. Once the automatic retry has been launched, the run ID of the retry is added to the original run.
  • When canceling a backfill of a job, the backfill daemon will now cancel all runs launched by that backfill before marking the backfill as canceled.
  • Dagster execution info (tags such as dagster/run-id, dagster/code-location, dagster/user and Dagster Cloud environment variables) typically attached to external resources are now available under DagsterRun.dagster_execution_info.
  • SensorReturnTypesUnion is now exported for typing the output of sensor functions.
  • [dagster-dbt] dbt seeds now get a valid code version (Thanks @marijncv!).
  • Manual and automatic retries of runs launched by backfills that occur while the backfill is still in progress are now incorporated into the backfill's status.
  • Manual retries of runs launched by backfills are no longer considered part of the backfill if the backfill is complete when the retry is launched.
  • [dagster-fivetran] Fivetran assets can now be materialized using the FivetranWorkspace.sync_and_poll(…) method in the definition of a @fivetran_assets decorator.
  • [dagster-fivetran] load_fivetran_asset_specs has been updated to accept an instance of DagsterFivetranTranslator or custom subclass.
  • [dagster-fivetran] The fivetran_assets decorator was added. It can be used with the FivetranWorkspace resource and DagsterFivetranTranslator translator to load Fivetran tables for a given connector as assets in Dagster. The build_fivetran_assets_definitions factory can be used to create assets for all the connectors in your Fivetran workspace.
  • [dagster-aws] ECSPipesClient.run now waits up to 70 days for tasks completion (waiter parameters are configurable) (Thanks @jenkoian!)
  • [dagster-dbt] Update dagster-dbt scaffold template to be compatible with uv (Thanks @wingyplus!).
  • [dagster-airbyte] A load_airbyte_cloud_asset_specs function has been added. It can be used with the AirbyteCloudWorkspace resource and DagsterAirbyteTranslator translator to load your Airbyte Cloud connection streams as external assets in Dagster.
  • [ui] Add an icon for the icechunk kind.
  • [ui] Improved ui for manual sensor/schedule evaluation.

Bugfixes#

  • Fixed database locking bug for the ConsolidatedSqliteEventLogStorage, which is mostly used for tests.
  • [dagster-aws] Fixed a bug in the ECSRunLauncher that prevented it from accepting a user-provided task definition when DAGSTER_CURRENT_IMAGE was not set in the code location.
  • [ui] Fixed an issue that would sometimes cause the asset graph to fail to render on initial load.
  • [ui] Fix global auto-materialize tick timeline when paginating.

1.9.4 (core) / 0.25.4 (libraries)#

New#

  • Global op concurrency is now enabled on the default SQLite storage. Deployments that have not been migrated since 1.6.0 may need to run dagster instance migrate to enable.
  • Introduced map_asset_specs to enable modifying AssetSpecs and AssetsDefinitions in bulk.
  • Introduced AssetSpec.replace_attributes and AssetSpec.merge_attributes to easily alter properties of an asset spec.
  • [ui] Add a "View logs" button to open tick logs in the sensor tick history table.
  • [ui] Add Spanner kind icon.
  • [ui] The asset catalog now supports filtering using the asset selection syntax.
  • [dagster-pipes, dagster-aws] PipesS3MessageReader now has a new parameter include_stdio_in_messages which enables log forwarding to Dagster via Pipes messages.
  • [dagster-pipes] Experimental: A new Dagster Pipes message type log_external_stream has been added. It can be used to forward external logs to Dagster via Pipes messages.
  • [dagster-powerbi] Opts in to using admin scan APIs to pull data from a Power BI instance. This can be disabled by passing load_powerbi_asset_specs(..., use_workspace_scan=False).
  • [dagster-sigma] Introduced an experimental dagster-sigma snapshot command, allowing Sigma workspaces to be captured to a file for faster subsequent loading.

Bugfixes#

  • Fixed a bug that caused DagsterExecutionStepNotFoundError errors when trying to execute an asset check step of a run launched by a backfill.
  • Fixed an issue where invalid cron strings like "0 0 30 2 *" that represented invalid dates in February were still allowed as Dagster cron strings, but then failed during schedule execution. Now, these invalid cronstrings will raise an exception when they are first loaded.
  • Fixed a bug where owners added to AssetOuts when defining a @graph_multi_asset were not added to the underlying AssetsDefinition.
  • Fixed a bug where using the & or | operators on AutomationConditions with labels would cause that label to be erased.
  • [ui] Launching partitioned asset jobs from the launchpad now warns if no partition is selected.
  • [ui] Fixed unnecessary middle truncation occurring in dialogs.
  • [ui] Fixed timestamp labels and "Now" line rendering bugs on the sensor tick timeline.
  • [ui] Opening Dagster's UI with a single job defined takes you to the Overview page rather than the Job page.

  • [dagster-looker] DagsterLookerApiTranslator.get_asset_key is deprecated in favor of DagsterLookerApiTranslator.get_asset_spec().key
  • [dagster-sigma] DagsterSigmaTranslator.get_asset_key is deprecated in favor of DagsterSigmaTranslator.get_asset_spec().key
  • [dagster-tableau] DagsterTableauTranslator.get_asset_key is deprecated in favor of DagsterTableauTranslator.get_asset_spec().key

1.9.3 (core) / 0.25.3 (libraries)#

New#

  • Fixed an issue with AutomationCondition.run_in_progress that would cause it to ignore queued runs.
  • Fixed an issue that would cause a default_automation_condition_sensor to be constructed for user code servers running on dagster version < 1.9.0 even if the legacy auto_materialize: use_sensors configuration setting was set to False.
  • [ui] Fixed an issue when executing asset checks where the wrong job name was used in some situations. The correct job name is now used.

1.9.0 (core) / 0.25.0 (libraries)#

Major changes since 1.8.0 (core) / 0.24.0 (libraries)#

Automation#

  • Declarative Automation, the system which enables setting per-asset AutomationConditions, is no longer experimental. We now recommend using this system in all cases where asset-centric orchestration is desired. A suite of built-in static constructors have been added for common usecases, such as AutomationCondition.on_missing() (which can fill in missing partitions of assets as soon as upstream data is available), and AutomationCondition.all_deps_blocking_checks_passed() (which can prevent materialization of assets until all upstream blocking checks have passed).
  • You can now assign AutomationConditions to asset checks, via the automation_condition parameter on @asset_check or AssetCheckSpec.
  • You can now assign AutomationConditions to observable source assets, via the automation_condition parameter on @observable_source_asset.
  • [experimental] You can now define custom subclasses of AutomationCondition to execute arbitrary Python code in the context of a broader expression. This allows you to compose built-in conditions with custom business logic.
  • The target arguments on schedules and sensors are now marked stable, allowing a stable way for schedules and sensors to target asset selections without needing to define a job.

Integrations#

  • Introduced a slate of integrations with business intelligence (BI) tools, enabling dashboards, views, and reports to be represented in the Dagster asset graph.
  • A rich set of metadata is now automatically collected by our suite of ELT integrations.
    • The dagster/table_name metadata tag, containing the fully-qualified name of the destination model, has been added for Airbyte, dlt, Fivetran and Sling assets.
    • The dagster/row_count metadata tag, containing the number of records loaded in the corresponding run, has been added for dlt and Sling assets.
    • The dagster/column_schema metadata tag, containing column schema information of the destination tables, has been added for Fivetran assets.
    • Column lineage information is now collected for Sling assets.
  • dagster-pipes are replacing the now deprecated Step Launchers as the new recommended approach for executing remote Spark jobs. Three new Pipes clients for running Spark applications on Amazon Web Services have been added:
    • dagster_aws.pipes.PipesGlueClient
    • dagster_aws.pipes.PipesEMRServerlessClient
    • dagster_aws.pipes.PipesEMRClient

UI#

  • Several changes have been made to the information architecture to make it easier to find what you’re looking for:
    • Backfills have been moved from their own tab underneath the Overview page to entries within the table on the Runs page. This reflects the fact that backfills and runs are similar entities that share most properties. You can continue to use the legacy Runs page with the “Revert to legacy Runs page” user setting. (GitHub Discussion)
    • “Jobs” is now a page reachable from the top-level navigation pane. It replaces the Jobs tab within the Overview page.
    • “Automations” is now a page reachable from the top-level navigation pane. It replaces the schedule and sensor tabs within the Overview page.
  • @asset and AssetSpec now have a kinds attribute that enables specifying labels that show up on asset nodes in the asset graph in the UI. This supersedes the compute_kind attribute.

Changes since 1.8.13 (core) / 0.24.13 (libraries)#

New#

  • The tags parameter to @asset and AssetSpec is no longer marked as experimental.
  • The @observable_source_asset decorator now supports an automation_condition argument.
  • AutomationCondition and associated APIs are no longer marked as experimental.
  • Added a new use_user_code_server parameter to AutomationConditionSensorDefinition. If set, the sensor will be evaluated in the user code server (as traditional sensors are), allowing custom AutomationCondition subclasses to be evaluated.
  • Added a new column to the BulkActions table, a new column to the Runs table, and a new BackfillTags table to improve the performance of the Runs page. To take advantage of these performance improvements, run dagster instance migrate. This migration involves a schema migration to add the new columns and table, and a data migration to populate the new columns for historical backfills and runs.
  • Performance improvements when loading definitions with multi-assets with many asset keys.
  • [ui] The previously-experimental changes to the top nav are now enabled for all users.
  • [ui] Added new code location pages which provide information regarding library versions, metadata, and definitions.
  • [ui] The new version of the Runs page is now enabled by default. To use the legacy version of the Runs page, toggle the "Revert to legacy Runs page" user setting.
  • [ui] Clicking an asset with failed partitions on the asset health overview now takes you to a list of the failed partitions.
  • [ui] The Materialize button runs pre-flight checks more efficiently, resulting in faster run launch times.
  • [dagster-pipes] Added support for multi-container log streaming (thanks, @MattyKuzyk!)
  • [dagster-docker] container_kwargs.stop_timeout can now be set when using the DockerRunLauncher or docker_executor to configure the amount of time that Docker will wait when terminating a run for it to clean up before forcibly stopping it with a SIGKILL signal.
  • [dagster-dbt] Performance improvements when loading definitions using build_dbt_asset_selection.

Bugfixes#

  • [ui] Fixed redirect behavior on full pageloads of the legacy auto-materialize overview page.
  • [ui] Plots for assets that emit materialization and observation events at different rates no longer display a time period missing the more frequent event type.
  • [ui] Fixed issue causing scrolling to misbehave on the concurrency settings page.
  • [helm] The blockOpConcurrencyLimitedRuns section of queuedRunCoordinator now correctly templates the appropriate config.
  • [dagster-pipes] Fixed issue where k8s ops would fail after 4 hours (thanks, @MattyKuzyk!)

Documentation#

  • [dagster-dbt] Added guide for using dbt defer with Dagster branch deployments.
  • [docs] Step Launchers documentation has been removed and replaced with references to Dagster Pipes.
  • [docs] Fixed code example in Dagster Essentials (thanks, @aleexharris!)

Breaking Changes#

  • dagster no longer supports Python 3.8, which hit EOL on 2024-10-07.
  • dagster now requires pydantic>=2.
  • By default, AutomationConditionSensorDefinitions will now emit backfills to handle cases where more than one partition of an asset is requested on a given tick. This allows that asset's BackfillPolicy to be respected. This feature can be disabled by setting allow_backfills to False.
  • Passing a custom PartitionsDefinition subclass into a Definitions object now issues an error instead of a deprecation warning.
  • AssetExecutionContext is no longer a subclass of OpExecutionContext. At this release, AssetExecutionContext and OpExecutionContext implement the same methods, but in the future, the methods implemented by each class may diverge. If you have written helper functions with OpExecutionContext type annotations, they may need to be updated to include AssetExecutionContext depending on your usage. Explicit calls to isinstance(context, OpExecutionContext) will now fail if context is an AssetExecutionContext.
  • The asset_selection parameter on AutomationConditionSensorDefinition has been renamed to target, to align with existing sensor APIs.
  • The experimental freshness_policy_sensor has been removed, as it relies on the long-deprecated FreshnessPolicy API.
  • The deprecated external_assets_from_specs and external_asset_from_spec methods have been removed. Users should use AssetsDefinition(specs=[...]), or pass specs directly into the Definitions object instead.
  • AssetKey objects can no longer be iterated over or indexed in to. This behavior was never an intended access pattern and in all observed cases was a mistake.
  • The dagster/relation_identifier metadata key has been renamed to dagster/table_name.
  • [dagster-ge] dagster-ge now only supports great_expectations>=0.17.15. The ge_validation_op_factory API has been replaced with the API previously called ge_validation_op_factory_v3.
  • [dagster-aws] Removed deprecated parameters from dagster_aws.pipes.PipesGlueClient.run.
  • [dagster-embedded-elt] Removed deprecated parameter dlt_dagster_translator from @dlt_assets. The dagster_dlt_translator parameter should be used instead.
  • [dagster-polars] Dropped support for saving storage-level arbitrary metadata via IOManagers.

Deprecations#

  • The DataBricksPysparkStepLauncher, EmrPySparkStepLauncher, and any custom subclass of StepLauncher have been marked as deprecated, but will not be removed from the codebase until Dagster 2.0 is released, meaning they will continue to function as they currently do for the foreseeable future. Their functionality has been superseded by the interfaces provided by dagster-pipes, and so future development work will be focused there.
  • The experimental multi_asset_sensor has been marked as deprecated, as its main use cases have been superseded by the AutomationCondition APIs. However, it will not be removed until version 2.0.0.

1.8.13 (core) / 0.24.13 (libraries)#

New#

  • Performance improvements when loading code locations using multi-assets with many asset keys.
  • AutomationCondition.in_progress() now will be true if an asset partition is part of an in-progress backfill that has not yet executed it. The prior behavior, which only considered runs, is encapsulated in AutomationCondition.execution_in_progress().
  • [ui] Added tag filter to the jobs page.
  • [ui] Preserve user login state for a longer period of time.
  • [dagster-dbt] Performance improvements when loading definitions using build_dbt_asset_selection.
  • [dagster-docker] container_kwargs.stop_timeout can now be set when using the DockerRunLauncher or docker_executor to configure the amount of time that Docker will wait when terminating a run for it to clean up before forcibly stopping it with a SIGKILL signal.
  • [dagster-sigma] The Sigma integration now fetches initial API responses in parallel, speeding up initial load.
  • [dagster-looker] Attempt to naively render liquid templates for derived table sql.
  • [dagster-looker] Added support for views and explores that rely on refinements or extends.
  • [dagster-looker] When fetching explores and dashboards from the Looker API, retrieve in parallel.

Bugfixes#

  • Fixed an issue with AutomationCondition.eager() that could cause it to attempt to launch a second attempt of an asset in cases where it was skipped or failed during a run where one of its parents successfully materialized.
  • Fixed an issue which would cause AutomationConditionSensorDefinitions to not be evaluated if the use_user_code_server value was toggled after the initial evaluation.
  • Fixed an issue where configuration values for aliased pydantic fields would be dropped.
  • [ui] Fix an issue in the code locations page where invalid query parameters could crash the page.
  • [ui] Fix navigation between deployments when query parameters are present in the URL.
  • [helm] the blockOpConcurrencyLimitedRuns section of queuedRunCoordinator now correctly templates the appropriate config.
  • [dagster-sigma] Fixed pulling incomplete data for very large workspaces.

1.8.12 (core) / 0.24.12 (libraries)#

New#

  • The AutomationCondition.eager(), AutomationCondition.missing(), and AutomationCondition.on_cron conditions are now compatible with asset checks.
  • Added AssetSelection.materializable(), which returns only assets that are materializable in an existing selection.
  • Added a new AutomationCondition.all_deps_blocking_checks_passed condition, which can be used to prevent materialization when any upstream blocking checks have failed.
  • Added a code_version parameter to the @graph_asset decorator.
  • If a LaunchPartitionBackfill mutation is submitted to GQL with invalid partition keys, it will now return an early PartitionKeysNotFoundError.
  • AssetSelection.checks_for_assets now accepts AssetKeys and string asset keys, in addition to AssetsDefinitions.
  • [ui] Added a search bar to partitions tab on the asset details page.
  • [ui] Restored docked left nav behavior for wide viewports.
  • [dagster-aws] get_objects now has a since_last_modified that enables only fetching objects modified after a given timestamp.
  • [dagster-aws] New AWS EMR Dagster Pipes client (dagster_aws.pipes.PipesEMRCLient ) for running and monitoring AWS EMR jobs from Dagster.
  • [dagster-looker] Pinned the looker-sdk dependency below 24.18.0 to avoid this issue: https://github.com/looker-open-source/sdk-codegen/issues/1518.

Bugfixes#

  • Fixed an issue which could cause incorrect evaluation results when using self-dependent partition mappings with AutomationConditions that operate over dependencies.
  • [ui] Fixed an issue where the breadcumb on asset pages would flicker nonstop.
  • [dagster-embedded-elt] Fixed extraction of metadata for dlt assets whose source and destination identifiers differ.
  • [dagster-databricks] Fixed a permissioning gap that existed with the DatabricksPySparkStepLauncher, so that permissions are now set correctly for non-admin users.
  • [dagster-dbt] Fixed an issue where column metadata generated with fetch_column_metadata did not work properly for models imported through dbt dependencies.

Documentation#

  • [dagster-k8s] DagsterK8sPipesClient.run now shows up in API docs.

Dagster Plus#

1.8.11 (core) / 0.24.11 (libraries)#

New#

  • [experimental] AutomationCondition.eager() will now only launch runs for missing partitions which become missing after the condition has been added to the asset. This avoids situations in which the eager policy kicks off a large amount of work when added to an asset with many missing historical static/dynamic partitions.
  • [experimental] Added a new AutomationCondition.asset_matches() condition, which can apply a condition against an arbitrary asset in the graph.
  • [experimental] Added the ability to specify multiple kinds for an asset with the kinds parameter.
  • [dagster-github] Added create_pull_request method on GithubClient that enables creating a pull request.
  • [dagster-github] Added create_ref method on GithubClient that enables creating a new branch.
  • [dagster-embedded-elt] dlt assets now generate column metadata for child tables.
  • [dagster-embedded-elt] dlt assets can now fetch row count metadata with dlt.run(...).fetch_row_count() for both partitioned and non-partitioned assets. Thanks @kristianandre!
  • [dagster-airbyte] relation identifier metadata is now attached to Airbyte assets.
  • [dagster-embedded-elt] relation identifier metadata is now attached to sling assets.
  • [dagster-embedded-elt] relation identifier metadata is now attached to dlt assets.

Bugfixes#

  • PartitionedConfig objects can now return a RunConfig without causing a crash.
  • Corrected the AssetIn.__new__ typing for the dagster_type argument.
  • [dagster-embedded-elt] dlt assets now generate correct column metadata after the first materialization.
  • [dagster-embedded-elt] Sling's fetch_row_count() method now works for databases returning uppercase column names. Thanks @kristianandre!
  • [dagster-gcp] Ensure blob download is flushed to temporary file for GCSFileManager.read operations. Thanks @ollie-bell!

Dagster Plus#

  • Fixed a bug in the catalog UI where owners filters were not applied correctly.

1.8.10 (core) / 0.24.10 (libraries)#

New#

  • JobDefinition, @job, and define_asset_job now take a run_tags parameter. If run_tags are defined, they will be attached to all runs of the job, and tags will not be. If run_tags is not set, then tags are attached to all runs of the job (status quo behavior). This change enables the separation of definition-level and run-level tags on jobs.
  • Then env var DAGSTER_COMPUTE_LOG_TAIL_WAIT_AFTER_FINISH can now be used to pause before capturing logs (thanks @HynekBlaha!)
  • The kinds parameter is now available on AssetSpec.
  • OutputContext now exposes the AssetSpec of the asset that is being stored as an output (thanks, @marijncv!)
  • [experimental] Backfills are incorporated into the Runs page to improve observability and provide a more simplified UI. See the GitHub discussion for more details.
  • [ui] The updated navigation is now enabled for all users. You can revert to the legacy navigation via a feature flag. See GitHub discussion for more.
  • [ui] Improved performance for loading partition statuses of an asset job.
  • [dagster-docker] Run containers launched by the DockerRunLauncher now include dagster/job_name and dagster/run_id labels.
  • [dagster-aws] The ECS launcher now automatically retries transient ECS RunTask failures (like capacity placement failures).

Bugfixes#

  • Changed the log volume for global concurrency blocked runs in the run coordinator to be less spammy.
  • [ui] Asset checks are now visible in the run page header when launched from a schedule.
  • [ui] Fixed asset group outlines not rendering properly in Safari.
  • [ui] Reporting a materialization event now removes the asset from the asset health "Execution failures" list and returns the asset to a green / success state.
  • [ui] When setting an AutomationCondition on an asset, the label of this condition will now be shown in the sidebar on the Asset Details page.
  • [ui] Previously, filtering runs by Created date would include runs that had been updated after the lower bound of the requested time range. This has been updated so that only runs created after the lower bound will be included.
  • [ui] When using the new experimental navigation flag, added a fix for the automations page for code locations that have schedules but no sensors.
  • [ui] Fixed tag wrapping on asset column schema table.
  • [ui] Restored object counts on the code location list view.
  • [ui] Padding when displaying warnings on unsupported run coordinators has been corrected (thanks @hainenber!)
  • [dagster-k8s] Fixed an issue where run termination sometimes did not terminate all step processes when using the k8s_job_executor, if the termination was initiated while it was in the middle of launching a step pod.

Documentation#

  • Corrections on the Dagster instance concept page (thanks @mheguy!)
  • Corrections on the code locations concept page (thanks @tiberiuana!)
  • Repeated words removed (thanks @tianzedavid!)
  • [dagster-deltalake] Corrections and improvements (thanks @avriiil!)
  • [dagster-aws] Added docs for PipesEMRServerlessClient.

  • [dagster-dbt] Corrected sample sql code (thanks @b-per!)

1.8.9 (core) / 0.24.9 (libraries)#

New#

  • AssetSpec now has a with_io_manager_key method that returns an AssetSpec with the appropriate metadata entry to dictate the key for the IO manager used to load it. The deprecation warning for SourceAsset now references this method.
  • Added a max_runtime_seconds configuration option to run monitoring, allowing you to specify that any run in your Dagster deployment should terminate if it exceeds a certain runtime. Prevoiusly, jobs had to be individually tagged with a dagster/max_runtime tag in order to take advantage of this feature. Jobs and runs can still be tagged in order to override this value for an individual run.
  • It is now possible to set both tags and a custom execution_fn on a ScheduleDefinition. Schedule tags are intended to annotate the definition and can be used to search and filter in the UI. They will not be attached to run requests emitted from the schedule if a custom execution_fn is provided. If no custom execution_fn is provided, then for back-compatibility the tags will also be automatically attached to run requests emitted from the schedule.
  • SensorDefinition and all of its variants/decorators now accept a tags parameter. The tags annotate the definition and can be used to search and filter in the UI.
  • Added the dagster definitions validate command to Dagster CLI. This command validates if Dagster definitions are loadable.
  • [dagster-databricks] Databricks Pipes now allow running tasks in existing clusters.

Bugfixes#

  • Fixed an issue where calling build_op_context in a unit test would sometimes raise a TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object Exception on process shutdown.
  • [dagster-webserver] Fix an issue where the incorrect sensor/schedule state would appear when using DefaultScheduleStatus.STOPPED / DefaultSensorStatus.STOPPED after performing a reset.

Documentation#

  • [dagster-pipes] Fixed inconsistencies in the k8s pipes example.
  • [dagster-pandas-pyspark] Fixed example in the Spark/Pandas SDA guide.

Dagster Plus#

  • Fixed an issue where users with Launcher permissions for a particular code location were not able to cancel backfills targeting only assets in that code location.
  • Fixed an issue preventing long-running alerts from being sent when there was a quick subsequent run.

1.8.8 (core) / 0.24.8 (libraries)#

New#

  • Added --partition-range option to dagster asset materialize CLI. This option only works for assets with single-run Backfill Policies.
  • Added a new .without() method to AutomationCondition.eager(), AutomationCondition.on_cron(), and AutomationCondition.on_missing() which allows sub-conditions to be removed, e.g. AutomationCondition.eager().without(AutomationCondition.in_latest_time_window()).
  • Added AutomationCondition.on_missing(), which materializes an asset partition as soon as all of its parent partitions are filled in.
  • pyproject.toml can now load multiple Python modules as individual Code Locations. Thanks, @bdart!
  • [ui] If a code location has errors, a button will be shown to view the error on any page in the UI.
  • [dagster-adls2] The ADLS2PickleIOManager now accepts lease_duration configuration. Thanks, @0xfabioo!
  • [dagster-embedded-elt] Added an option to fetch row count metadata after running a Sling sync by calling sling.replicate(...).fetch_row_count().
  • [dagster-fivetran] The dagster-fivetran integration will now automatically pull and attach column schema metadata after each sync.

Bugfixes#

  • Fixed an issue which could cause errors when using AutomationCondition.any_downstream_condition() with downstream AutoMaterializePolicy objects.
  • Fixed an issue where process_config_and_initialize did not properly handle processing nested resource config.
  • [ui] Fixed an issue that would cause some AutomationCondition evaluations to be labeled DepConditionWrapperCondition instead of the key that they were evaluated against.
  • [dagster-webserver] Fixed an issue with code locations appearing in fluctuating incorrect state in deployments with multiple webserver processes.
  • [dagster-embedded-elt] Fixed an issue where Sling column lineage did not correctly resolve int the Dagster UI.
  • [dagster-k8s] The wait_for_pod check now waits until all pods are available, rather than erroneously returning after the first pod becomes available. Thanks @easontm!

Dagster Plus#

  • Backfill daemon logs are now available in the "Coordinator Logs" tab in a backfill details page.
  • Users without proper code location permissions can no longer edit sensor cursors.

1.8.7 (core) / 0.24.7 (libraries)#

New#

  • The AssetSpec constructor now raises an error if an invalid group name is provided, instead of an error being raised when constructing the Definitions object.
  • dagster/relation_identifier metadata is now automatically attached to assets which are stored using a DbIOManager.
  • [ui] Streamlined the code location list view.
  • [ui] The “group by” selection on the Timeline Overview page is now part of the query parameters, meaning it will be retained when linked to directly or when navigating between pages.
  • [dagster-dbt] When instantiating DbtCliResource, the project_dir argument will now override the DBT_PROJECT_DIR environment variable if it exists in the local environment (thanks, @marijncv!).
  • [dagster-embedded-elt] dlt assets now generate rows_loaded metadata (thanks, @kristianandre!).
  • Added support for pydantic version 1.9.0.

Bugfixes#

  • Fixed bug where the tick status filter for batch-fetched graphql sensors was not being respected.
  • [examples] Fixed missing assets in assets_dbt_python example.
  • [dagster-airbyte] Updated the op names generated for Airbyte assets to include the full connection ID, avoiding name collisions.
  • [dagster-dbt] Fixed issue causing dagster-dbt to be unable to load dbt projects where the adapter did not have a database field set (thanks, @dargmuesli!)
  • [dagster-dbt] Removed a warning about not being able to load the dbt.adapters.duckdb module when loading dbt assets without that package installed.

Documentation#

  • Fixed typo on the automation concepts page (thanks, @oedokumaci!)

Dagster Plus#

  • You may now wipe specific asset partitions directly from the execution context in user code by calling DagsterInstance.wipe_asset_partitions.
  • Dagster+ users with a "Viewer" role can now create private catalog views.
  • Fixed an issue where the default IOManager used by Dagster+ Serverless did not respect setting allow_missing_partitions as metadata on a downstream asset.

1.8.6 (core) / 0.24.6 (libraries)#

Bugfixes#

  • Fixed an issue where runs in Dagster+ Serverless that materialized partitioned assets would sometimes fail with an object has no attribute '_base_path' error.
  • [dagster-graphql] Fixed an issue where the statuses filter argument to the sensorsOrError GraphQL field was sometimes ignored when querying GraphQL for multiple sensors at the same time.

  • [dagster-dbt] Increased the default timeout when terminating a run that is running a dbt subprocess to wait 25 seconds for the subprocess to cleanly terminate. Previously, it would only wait 2 seconds.
  • [dagster-sdf] Increased the default timeout when terminating a run that is running an sdf subprocess to wait 25 seconds for the subprocess to cleanly terminate. Previously, it would only wait 2 seconds.
  • [dagster-sdf] Added support for caching and asset selection (Thanks, akbog!)
  • [dagster-dlt] Added support for AutomationCondition using DagsterDltTranslator.get_automation_condition() (Thanks, aksestok!)
  • [dagster-k8s] Added support for setting dagsterDaemon.runRetries.retryOnAssetOrOpFailure to False in the Dagster Helm chart to prevent op retries and run retries from simultaneously firing on the same failure.
  • [dagster-wandb] Removed usage of deprecated recursive parameter (Thanks, chrishiste!)

Bugfixes#

  • [dagster-k8s] Fixed an issue where Kubernetes Pipes failed to create a pod if the op name contained capital or non-alphanumeric containers.
  • [dagster-embedded-elt] Fixed an issue where dbt assets downstream of Sling were skipped

Deprecations#

  • [dagser-aws]: Direct AWS API arguments in PipesGlueClient.run have been deprecated and will be removed in 1.9.0. The new params argument should be used instead.

Dagster Plus#

  • Fixed a bug that caused an error when loading the launchpad for a partition, when using Dagster+ with an agent with version below 1.8.2.
  • Fixed an issue where terminating a Dagster+ Serverless run wouldn’t forward the termination signal to the job to allow it to cleanly terminate.

1.8.3 (core) / 0.24.3 (libraries) (YANKED - This version of Dagster resulted in errors when trying to launch runs that target individual asset partitions)#

New#

  • When different assets within a code location have different PartitionsDefinitions, there will no longer be an implicit asset job __ASSET_JOB_... for each PartitionsDefinition; there will just be one with all the assets. This reduces the time it takes to load code locations with assets with many different PartitionsDefinitions.

1.8.2 (core) / 0.24.2 (libraries)#

New#

  • [ui] Improved performance of the Automation history view for partitioned assets
  • [ui] You can now delete dynamic partitions for an asset from the ui

1.8.0 (core) / 0.24.0 (libraries)#

Major changes since 1.7.0 (core) / 0.22.0 (libraries)#

Core definition APIs#

  • You can now pass AssetSpec objects to the assets argument of Definitions, to let Dagster know about assets without associated materialization functions. This replaces the experimental external_assets_from_specs API, as well as SourceAssets, which are now deprecated. Unlike SourceAssets, AssetSpecs can be used for non-materializable assets with dependencies on Dagster assets, such as BI dashboards that live downstream of warehouse tables that are orchestrated by Dagster. [docs].
  • [Experimental] You can now merge Definitions objects together into a single larger Definitions object, using the new Definitions.merge API (doc). This makes it easier to structure large Dagster projects, as you can construct a Definitions object for each sub-domain and then merge them together at the top level.

Partitions and backfills#

  • BackfillPolicys assigned to assets are now respected for backfills launched from jobs that target those assets.
  • You can now wipe materializations for individual asset partitions.

Automation#

  • [Experimental] You can now add AutomationConditions to your assets to have them automatically executed in response to specific conditions (docs). These serve as a drop-in replacement and improvement over the AutoMaterializePolicy system, which is being marked as deprecated.
  • [Experimental] Sensors and schedules can now directly target assets, via the new target parameter, instead of needing to construct a job.
  • [Experimental] The Timeline page can now be grouped by job or automation. When grouped by automation, all runs launched by a sensor responsible for evaluating automation conditions will get bucketed to that sensor in the timeline instead of the "Ad-hoc materializations" row. Enable this by opting in to the Experimental navigation feature flag in user settings.

Catalog#

  • The Asset Details page now prominently displays row count and relation identifier (table name, schema, database), when corresponding asset metadata values are provided. For more information, see the metadata and tags docs.
  • Introduced code reference metadata which can be used to open local files in your editor, or files in source control in your browser. Dagster can automatically attach code references to your assets’ Python source. For more information, see the docs.

Data quality and reliability#

  • [Experimental] Metadata bound checks – The new build_metadata_bounds_checks API [doc] enables easily defining asset checks that fail if a numeric asset metadata value falls outside given bounds.
  • [Experimental] Freshness checks from dbt config - Freshness checks can now be set on dbt assets, straight from dbt. Check out the API docs for build_freshness_checks_from_dbt_assets for more.

Integrations#

  • Dagster Pipes (PipesSubprocessClient) and its integrations with Lambda (PipesLambdaClient), Kubernetes (PipesK8sClient), and Databricks (PipesDatabricksClient) are no longer experimental.
  • The new DbtProject class (docs) makes it simpler to define dbt assets that can be constructed in both development and production. DbtProject.prepare_if_dev() eliminates boilerplate for local development, and the dagster-dbt project prepare-and-package CLI can helps pull deps and generate the manifest at build time.
  • [Experimental] The dagster-looker package can be used to define a set of Dagster assets from a Looker project that is defined in LookML and is backed by git. See the GitHub discussion for more details.

Dagster Plus#

  • Catalog views — In Dagster+, selections into the catalog can now be saved and shared across an organization as catalog views. Catalog views have a name and description, and can be applied to scope the catalog, asset health, and global asset lineage pages against the view’s saved selection.
  • Code location history — Dagster+ now stores a history of code location deploys, including the ability to revert to a previously deployed configuration.

Changes since 1.7.16 (core) / 0.22.16 (libraries)#

New#

  • The target of both schedules and sensors can now be set using an experimental target parameter that accepts an AssetSelection or list of assets. Any assets passed this way will also be included automatically in the assets list of the containing Definitions object.

  • ScheduleDefinition and SensorDefinition now have a target argument that can accept an AssetSelection.

  • You can now wipe materializations for individual asset partitions.

  • AssetSpec now has a partitions_def attribute. All the AssetSpecs provided to a @multi_asset must have the same partitions_def.

  • The assets argument on materialize now accepts AssetSpecs.

  • The assets argument on Definitions now accepts AssetSpecs.

  • The new merge method on Definitions enables combining multiple Definitions object into a single larger Definitions object with their combined contents.

  • Runs requested through the Declarative Automation system now have a dagster/from_automation_condition: true tag applied to them.

  • Changed the run tags query to be more performant. Thanks @egordm!

  • Dagster Pipes and its integrations with Lambda, Kubernetes, and Databricks are no longer experimental.

  • The Definitions constructor will no longer raise errors when the provided definitions aren’t mutually resolve-able – e.g. when there are conflicting definitions with the same name, unsatisfied resource dependencies, etc. These errors will still be raised at code location load time. The new Definitions.validate_loadable static method also allows performing the validation steps that used to occur in constructor.

  • AssetsDefinitions object provided to a Definitions object will now be deduped by reference equality. That is, the following will now work:

    from dagster import asset, Definitions
    
    @asset
    def my_asset(): ...
    
    defs = Definitions(assets=[my_asset, my_asset]) # Deduped into just one AssetsDefinition.
    
  • [dagster-embedded-elt] Adds translator options for dlt integration to override auto materialize policy, group name, owners, and tags

  • [dagster-sdf] Introducing the dagster-sdf integration for data modeling and transformations powered by sdf.

  • [dagster-dbt] Added a new with_insights() method which can be used to more easily attach Dagster+ Insights metrics to dbt executions: dbt.cli(...).stream().with_insights()

Bugfixes#

  • Dagster now raises an error when an op yields an output corresponding to an unselected asset.
  • Fixed a bug that caused downstream ops within a graph-backed asset to be skipped when they were downstream of assets within the graph-backed assets that aren’t part of the selection for the current run.
  • Fixed a bug where code references did not work properly for self-hosted GitLab instances. Thanks @cooperellidge!
  • [ui] When engine events with errors appear in run logs, their metadata entries are now rendered correctly.
  • [ui] The asset catalog greeting now uses your first name from your identity provider.
  • [ui] The create alert modal now links to the alerting documentation, and links to the documentation have been updated.
  • [ui] Fixed an issue introduced in the 1.7.13 release where some asset jobs were only displaying their ops in the Dagster UI instead of their assets.
  • Fixed an issue where terminating a run while it was using the Snowflake python connector would sometimes move it into a FAILURE state instead of a CANCELED state.
  • Fixed an issue where backfills would sometimes move into a FAILURE state instead of a CANCELED state when the backfill was canceled.

Breaking Changes#

  • The experimental and deprecated build_asset_with_blocking_check has been removed. Use the blocking argument on @asset_check instead.
  • Users with mypy and pydantic 1 may now experience a “metaclass conflict” error when using Config. Previously this would occur when using pydantic 2.
  • AutoMaterializeSensorDefinition has been renamed AutomationConditionSensorDefinition.
  • The deprecated methods of the ComputeLogManager have been removed. Custom ComputeLogManager implementations must also implement the CapturedLogManager interface. This will not affect any of the core implementations available in the core dagster package or the library packages.
  • By default, an AutomationConditionSensorDefinition with the name “default_automation_condition_sensor” will be constructed for each code location, and will handle evaluating and launching runs for all AutomationConditions and AutoMaterializePolicies within that code location. You can restore the previous behavior by setting:
    auto_materialize:
      use_sensors: False
    
    in your dagster.yaml file.
  • [dagster-dbt] Support for dbt-core==1.6.* has been removed because the version is now end-of-life.
  • [dagster-dbt] The following deprecated APIs have been removed:
    • KeyPrefixDagsterDbtTranslator has been removed. To modify the asset keys for a set of dbt assets, implementDagsterDbtTranslator.get_asset_key() instead.
    • Support for setting freshness policies through dbt metadata on field +meta.dagster_freshness_policy has been removed. Use +meta.dagster.freshness_policy instead.
    • Support for setting auto-materialize policies through dbt metadata on field +meta.dagster_auto_materialize_policy has been removed. Use +meta.dagster.auto_materialize_policy instead.
    • Support for load_assets_from_dbt_project, load_assets_from_dbt_manifest, and dbt_cli_resource has been removed. Use @dbt_assets, DbtCliResource, and DbtProject instead to define how to load dbt assets from a dbt project and to execute them.
    • Support for rebuilt ops like dbt_run_op, dbt_compile_op, etc has been removed. Use @op and DbtCliResource directly to execute dbt commands in an op.
  • Properties on AssetExecutionContext , OpExecutionContext , and ScheduleExecutionContext that include datetimes now return standard Python datetime objects instead of Pendulum datetimes. The types in the public API for these properties have always been datetime and this change should not be breaking in the majority of cases, but Pendulum datetimes include some additional methods that are not present on standard Python datetimes, and any code that was using those methods will need to be updated to either no longer use those methods or transform the datetime into a Pendulum datetime. See the 1.8 migration guide for more information and examples.
  • MemoizableIOManager, VersionStrategy, SourceHashVersionStrategy, OpVersionContext, ResourceVersionContext, and MEMOIZED_RUN_TAG, which have been deprecated and experimental since pre-1.0, have been removed.

Deprecations#

  • The Run Status column of the Backfills page has been removed. This column was only populated for backfills of jobs. To see the run statuses for job backfills, click on the backfill ID to get to the Backfill Details page.
  • The experimental external_assets_from_specs API has been deprecated. Instead, you can directly pass AssetSpec objects to the assets argument of the Definitions constructor.
  • AutoMaterializePolicy has been marked as deprecated in favor of AutomationCondition , which provides a significantly more flexible and customizable interface for expressing when an asset should be executed. More details on how to migrate your AutoMaterializePolicies can be found in the Migration Guide.
  • SourceAsset has been deprecated. See the major changes section and migration guide for more details.
  • The asset_partition_key_for_output, asset_partition_keys_for_output, and asset_partition_key_range_for_output, and asset_partitions_time_window_for_output methods on OpExecutionContext have been deprecated. Instead, use the corresponding property: partition_key, partition_keys, partition_key_range, or partition_time_window.
  • The partitions_def parameter on define_asset_job is now deprecated. The partitions_def for an asset job is determined from the partitions_def attributes on the assets it targets, so this parameter is redundant.
  • [dagster-shell] create_shell_command_op and create_shell_script_op have been marked as deprecated in favor of PipesSubprocessClient (see details in Dagster Pipes subprocess reference)
  • [dagster-airbyte] load_assets_from_airbyte_project is now deprecated, because the Octavia CLI that it relies on is an experimental feature that is no longer supported. Use build_airbyte_assets or load_assets_from_airbyte_project instead.

Documentation#

  • The Asset Checks concept overview page now includes a table with all the built-in asset checks.
  • The Asset Metadata page concept page now includes a table with all the standard “dagster/” metadata keys.
  • Fixed a typo in the documentation for MonthlyPartitionsDefinition. Thanks @zero_stroke!
  • Added a new page about Declarative Automation and a guide about customizing automation conditions
  • Fixed a link in the Limiting concurrency guide.

Dagster Plus#

  • In Dagster+, selections into the catalog can now be saved and shared across an organization as catalog views. Catalog views have a name and description, and can be applied to scope the catalog, asset health, and global asset lineage pages against the view’s saved selection.
  • In Dagster+ run alerts, if you are running Dagster 1.8 or greater in your user code, you will now receive exception-level information in the alert body.

1.7.16 (core) / 0.23.16 (libraries)#

Experimental#

  • [pipes] PipesGlueClient, an AWS Glue pipes client has been added to dagster_aws.

1.7.15 (core) / 0.23.15 (libraries)#

New#

  • [dagster-celery-k8s] Added a per_step_k8s_config configuration option to the celery_k8s_job_executor , allowing the k8s configuration of individual steps to be configured at run launch time. Thanks @alekseik1!
  • [dagster-dbt] Deprecated the log_column_level_metadata macro in favor of the new with_column_metadata API.
  • [dagster-airbyte] Deprecated load_assets_from_airbyte_project as the Octavia CLI has been deprecated.

Bugfixes#

  • [ui] Fix global search to find matches on very long strings.
  • Fixed an issue introduced in the 1.7.14 release where multi-asset sensors would sometimes raise an error about fetching too many event records.
  • Fixes an issue introduced in 1.7.13 where type-checkers interpretted the return type of RunRequest(...) as None
  • [dagster-aws] Fixed an issue where the EcsRunLauncher would sometimes fail to launch runs when the include_sidecars option was set to True.
  • [dagster-dbt] Fixed an issue where errors would not propagate through deferred metadata fetches.

Dagster Plus#

  • On June 20, 2024, AWS changed the AWS CloudMap CreateService API to allow resource-level permissions. The Dagster+ ECS Agent uses this API to launch code locations. We’ve updated the Dagster+ ECS Agent CloudFormation template to accommodate this change for new users. Existing users have until October 14, 2024 to add the new permissions and should have already received similar communication directly from AWS.
  • Fixed a bug with BigQuery cost tracking in Dagster+ insights, where some runs would fail if there were null values for either total_byte_billed or total_slot_ms in the BigQuery INFORMATION_SCHEMA.JOBS table.
  • Fixed an issue where code locations that failed to load with extremely large error messages or stack traces would sometimes cause errors with agent heartbeats until the code location was redeployed.
