  • [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#

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!).

  • [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-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-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.

Experimental#

  • [dagster-ext] An initial version of the dagster-ext module along with subprocess, docker, databricks, and k8s pod integrations are now available. Read more at https://github.com/dagster-io/dagster/discussions/16319. Note that the module is temporarily being published to PyPI under dagster-ext-process, but is available in python as import dagster_ext.

  • Cron schedules targeting leap day (ending with 29 2 *) no longer cause exceptions in the UI or daemon.
  • Previously, if multiple partitioned observable_source_assets with different partition definitions existed in the same code location, runs targeting those assets could fail to launch. This has been fixed.
  • When using AutoMaterializePolicies with assets that depended on prior partitions of themselves, updating the start_date of their underlying PartitionsDefinition could result in runs being launched for partitions that no longer existed. This has been fixed.
  • Fixed an issue where auto-materilization could sometimes produce duplicate runs if there was an error in the middle of an auto-materialization tick.
  • [dagster-census] A recent change to the Census API broke compatibility with this integration. This has been fixed (thanks @ldnicolasmay!)

1.4.12 / 0.20.12 (libraries)#

New#

  • The context object now has an asset_key property to get the AssetKey of the current asset.
  • Performance improvements to the auto-materialize daemon when running on large asset graphs.
  • The dagster dev and dagster-daemon run commands now include a --log-level argument that allows you to customize the logger level threshold.
  • [dagster-airbyte] AirbyteResource now includes a poll_interval key that allows you to configure how often it checks an Airbyte sync’s status.

Bugfixes#

  • Fixed an issue where the dagster scheduler would sometimes raise an error if a schedule set its cron_schedule to a list of strings and also had its default status set to AUTOMATICALLY_RUNNING.
  • Fixed an issue where the auto-materialize daemon would sometimes raise a RecursionError when processing asset graphs with long upstream dependency chains.
  • [ui] Fixed an issue where the Raw Compute Logs dropdown on the Run page sometimes didn’t show the current step name or properly account for retried steps.

Community Contributions#

  • [dagster-databricks] Fixed a regression causing DatabricksStepLauncher to fail. Thanks @zyd14!
  • Fixed an issue where Dagster raised an exception when combining observable source assets with multiple partitions definitions. Thanks @aroig!
  • [dagster-databricks] Added support for client authentication with OAuth. Thanks @zyd14!
  • [dagster-databricks] Added support for workspace and volumes init scripts in the databricks client. Thanks @zyd14!
  • Fixed a missing import in our docs. Thanks @C0DK!

Experimental#

  • Asset checks are now displayed in the asset graph and sidebar.

  • [Breaking] Asset check severity is now set at runtime on AssetCheckResult instead of in the @asset_check definition. Now you can define one check that either errors or warns depending on your check logic. ERROR severity no longer causes the run to fail. We plan to reintroduce this functionality with a different API.

  • [Breaking] @asset_check now requires the asset= argument, even if the asset is passed as an input to the decorated function. Example:

    @asset_check(asset=my_asset)
    def my_check(my_asset) -> AssetCheckResult:
        ...
    
  • [Breaking] AssetCheckSpec now takes asset= instead of asset_key=, and can accept either a key or an asset definition.

  • [Bugfix] Asset checks now work on assets with key_prefix set.

  • [Bugfix] Execution failure asset checks are now displayed correctly on the checks tab.

Documentation#

  • [dagster-dbt] Added example of invoking DbtCliResource in custom asset/op to API docs.

  • The dagster execute job cli now accepts —-op-selection (thanks @silent-lad!)
  • [ui] Option (Alt) + R now reloads all code locations (OSS only)

Bugfixes#

  • Adds a check to validate partition mappings when directly constructing AssetsDefinition instances.
  • Assets invoked in composition functions like @graph and @job now work again, fixing a regression introduced in 1.4.5.
  • Fixed an issue where a race condition with parallel runs materializing the same asset could cause a run to raise a RecursionError during execution.
  • Fixed an issue where including a resource in both a schedule and a job raised a “Cannot specify resource requirements” exception when the definitions were loaded.
  • The ins argument to graph_asset is now respected correctly.
  • Fixed an issue where the daemon process could sometimes stop with a heartbeat failure when the first sensor it ran took a long time to execute.
  • Fixed an issue where dagster dev failed on startup when the DAGSTER_GRPC_PORT `environment variable was set in the environment.
  • deps arguments for an asset can now be specified as an iterable instead of a sequence, allowing for sets to be passed.
  • [dagster-aws] Fixed a bug where the S3PickleIOManager didn’t correctly handle missing partitions when allow_missing_partitions was set. Thanks @o-sirawat!
  • [dagster-k8s] in the helm chart, the daemon securityContext setting now applies correctly to all init containers (thanks @maowerner!)

Community Contributions#

  • [dagster-databricks] Migrated to use new official databricks Python SDK. Thanks @judahrand!

Experimental#

  • New APIs for defining and executing checks on software-defined assets. These APIs are very early and subject to change. The corresponding UI has limited functionality. Docs
  • Adds a new auto-materialize skip rule AutoMaterializeRule.skip_on_not_all_parents_updated that enforces that an asset can only be materialized if all parents have been materialized since the asset's last materialization.
  • Exposed an auto-materialize skip rule – AutoMaterializeRule.skip_on_parent_missing –which is already part of the behavior of the default auto-materialize policy.
  • Auto-materialize evaluation history will now be stored for 1 month, instead of 1 week.
  • The auto-materialize asset daemon now includes more logs about what it’s doing for each asset in each tick in the Dagster Daemon process output.

Documentation#

  • [dagster-dbt] Added reference docs for dagster-dbt project scaffold.

Dagster Cloud#

  • Fixed an issue where the Docker agent would sometimes fail to load code locations with long names with a hostname connection error.
