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.
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.
[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.
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).
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.
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.
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.
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.
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.
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!
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!).
Fixed a bug where setting asset_selection=[] on RunRequest objects yielded from sensors using asset_selection would select all assets instead of none.
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.
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.
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.
Updated multi-asset sensor definition to be less likely to timeout queries against the asset history storage.
Consolidated the CapturedLogManager and ComputeLogManager APIs into a single base class.
[ui] Added an option under user settings to clear client side indexeddb caches as an escape hatch for caching related bugs.
[dagster-aws, dagster-pipes] Added a new PipesECSClient to allow Dagster to interface with ECS tasks.
[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!)
[ui] Fixed a bug where in-progress runs from a backfill could not be terminated from the backfill UI.
[ui] Fixed a bug that caused an "Asset must be part of at least one job" error when clicking on an external asset in the asset graph UI
Fixed an issue where viewing run logs with the latest 5.0 release of the watchdog package raised an exception.
[ui] Fixed issue causing the “filter to group” action in the lineage graph to have no effect.
[ui] Fixed case sensitivity when searching for partitions in the launchpad.
[ui] Fixed a bug which would redirect to the events tab for an asset if you loaded the partitions tab directly.
[ui] Fixed issue causing runs to get skipped when paging through the runs list (Thanks, @HynekBlaha!)
[ui] Fixed a bug where the asset catalog list view for a particular group would show all assets.
[dagster-dbt] fix bug where empty newlines in raw dbt logs were not being handled correctly.
[dagster-k8s, dagster-celery-k8s] Correctly set dagster/image label when image is provided from user_defined_k8s_config. (Thanks, @HynekBlaha!)
[dagster-duckdb] Fixed an issue for DuckDB versions older than 1.0.0 where an unsupported configuration option, custom_user_agent, was provided by default
[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
[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.
The default io_manager on Serverless now supports the allow_missing_partitions configuration option.
Fixed a bug that caused an error when loading the launchpad for a partition, when using in Dagster+ with an agent with version below 1.8.2
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)#
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.
[ui] Fixed a collection of broken links pointing to renamed Declarative Automation pages.
[dagster-dbt] Fixed issue preventing usage of MultiPartitionMapping with @dbt_assets (Thanks, @arookieds!)
[dagster-azure] Fixed issue that would cause an error when configuring an AzureBlobComputeLogManager without a secret_key (Thanks, @ion-elgreco and @HynekBlaha!)
Dagster now automatically infers a dependency relationship between a time-partitioned asset and a multi-partitioned asset with a time dimension. Previously, this was only inferred when the time dimension was the same in each asset.
The EnvVar utility will now raise an exception if it is used outside of the context of a Dagster resource or config class. The get_value() utility will retrieve the value outside of this context.
[ui] The runs page now displays a “terminate all” button at the top, to bulk terminate in-progress runs.
[ui] Asset Graph - Various performance improvements that make navigating large asset graphs smooth
[ui] Asset Graph - The graph now only fetches data for assets within the viewport solving timeout issues with large asset graphs
[ui] Asset Graph Sidebar - The sidebar now shows asset status
[dagster-dbt] When executing dbt invocations using DbtCliResource, an explicit target_path can now be specified.
[dagster-dbt] Asset checks can now be enabled by using DagsterDbtTranslator and DagsterDbtTranslatorSettings: see the docs for more information.
[dagster-embedded-elt] Dagster library for embedded ELT
Improved ergonomics for execution dependencies in assets - We introduced a set of APIs to simplify working with Dagster that don't use the I/O manager system for handling data between assets. I/O manager workflows will not be affected.
AssetDep type allows you to specify upstream dependencies with partition mappings when using the deps parameter of @asset and AssetSpec.
MaterializeResult can be optionally returned from an asset to report metadata about the asset when the asset handles any storage requirements within the function body and does not use an I/O manager.
AssetSpec has been added as a new way to declare the assets produced by @multi_asset. When using AssetSpec, the multi_asset does not need to return any values to be stored by the I/O manager. Instead, the multi_asset should handle any storage requirements in the body of the function.
Asset checks (experimental) - You can now define, execute, and monitor data quality checks in Dagster [docs].
The @asset_check decorator, as well as the check_specs argument to @asset and @multi_asset enable defining asset checks.
Materializing assets from the UI will default to executing their asset checks. You can also execute individual checks.
When viewing an asset in the asset graph or the asset details page, you can see whether its checks have passed, failed, or haven’t run successfully.
Auto materialize customization (experimental) - AutoMaterializePolicies can now be customized [docs].
All policies are composed of a set of AutoMaterializeRules which determine if an asset should be materialized or skipped.
To modify the default behavior, rules can be added to or removed from a policy to change the conditions under which assets will be materialized.
Dagster pipes is a new library that implements a protocol for launching compute into external execution environments and consuming streaming logs and Dagster metadata from those environments. See https://github.com/dagster-io/dagster/discussions/16319 for more details on the motivation and vision behind Pipes.
Out-the-box integrations
Clients: local subprocess, Docker containers, Kubernetes, and Databricks
Dagster pipes is composable with existing launching infrastructure via open_pipes_session. One can augment existing invocations rather than replacing them wholesale.
[ui] Global Asset Graph performance improvement - the first time you load the graph it will be cached to disk and any subsequent load of the graph should load instantly.
will cause type checking errors. To migrate, update type hints to respect the new subclassing.
AssetExecutionContext cannot be used as the type annotation for @ops run in @jobs. To migrate, update the type hint in @op to OpExecutionContext. @ops that are used in @graph_assets may still use the AssetExecutionContext type hint.
[ui] We have removed the option to launch an asset backfill as a single run. To achieve this behavior, add backfill_policy=BackfillPolicy.single_run() to your assets.
has_dynamic_partition implementation has been optimized. Thanks @edvardlindelof!
[dagster-airbyte] Added an optional stream_to_asset_map argument to build_airbyte_assets to support the Airbyte prefix setting with special characters. Thanks @chollinger93!
[dagster-k8s] Moved “labels” to a lower precedence. Thanks @jrouly!
[dagster-k8s] Improved handling of failed jobs. Thanks @Milias!
[dagster-databricks] Fixed an issue where DatabricksPysparkStepLauncher fails to get logs when job_run doesn’t have cluster_id at root level. Thanks @PadenZach!
New dagster-insights sub-module - We have released an experimental dagster_cloud.dagster_insights module that contains utilities for capturing and submitting external metrics about data operations to Dagster Cloud via an api. Dagster Cloud Insights is a soon-to-be released feature that shows improves visibility into usage and cost metrics such as run duration and Snowflake credits in the Cloud UI.
[dagster-dbt] DbtCliResource now enforces that the current installed version of dbt-core is at least version 1.4.0.
[dagster-dbt] DbtCliResource now properly respects DBT_TARGET_PATH if it is set by the user. Artifacts from dbt invocations using DbtCliResource will now be placed in unique subdirectories of DBT_TARGET_PATH.
When executing a backfill that targets a range of time partitions in a single run, the partition_time_window attribute on OpExecutionContext and AssetExecutionContext now returns the time range, instead of raising an error.
Fixed an issue where the asset backfill page raised a GraphQL error for backfills that targeted different partitions per-asset.
Fixed job_name property on the result object of build_hook_context.
AssetSpec has been added as a new way to declare the assets produced by @multi_asset.
AssetDep type allows you to specify upstream dependencies with partition mappings when using the deps parameter of @asset and AssetSpec.
[dagster-ext] report_asset_check method added to ExtContext.
[dagster-ext] ext clients now must use yield from to forward reported materializations and asset check results to Dagster. Results reported from ext that are not yielded will raise an error.
The Dagster UI documentation got an overhaul! We’ve updated all our screenshots and added a number of previously undocumented pages/features, including:
The Overview page, aka the Factory Floor
Job run compute logs
Global asset lineage
Overview > Resources
The Resources documentation has been updated to include additional context about using resources, as well as when to use os.getenv() versus Dagster’s EnvVar.
Information about custom loggers has been moved from the Loggers documentation to its own page, Custom loggers.
[ui] When using the search input within Overview pages, if the viewer’s code locations have not yet fully loaded into the app, a loading spinner will now appear to indicate that search results are pending.
Fixed an asset backfill bug that caused occasionally caused duplicate runs to be kicked off in response to manual runs upstream.
Fixed an issue where launching a run from the Launchpad that included many assets would sometimes raise an exception when trying to create the tags for the run.
[ui] Fixed a bug where clicking to view a job from a run could lead to an empty page in situations where the viewer’s code locations had not yet loaded in the app.
The deps parameter for @asset and @multi_asset now supports directly passing @multi_asset definitions. If an @multi_asset is passed to deps, dependencies will be created on every asset produced by the @multi_asset.
Added an optional data migration to convert storage ids to use 64-bit integers instead of 32-bit integers. This will incur some downtime, but may be required for instances that are handling a large number of events. This migration can be invoked using dagster instance migrate --bigint-migration.
[ui] Dagster now allows you to run asset checks individually.
[ui] The run list and run details page now show the asset checks targeted by each run.
[ui] In the runs list, runs launched by schedules or sensors will now have tags that link directly to those schedules or sensors.
[ui] Clicking the "N assets" tag on a run allows you to navigate to the filtered asset graph as well as view the full list of asset keys.
[ui] Schedules, sensors, and observable source assets now appear on the resource “Uses” page.
[dagster-dbt] The DbtCliResource now validates at definition time that its project_dir and profiles_dir arguments are directories that respectively contain a dbt_project.yml and profiles.yml.
[dagster-databricks] You can now configure a policy_id for new clusters when using the databricks_pyspark_step_launcher (thanks @zyd14!)
[ui] Added an experimental sidebar to the Asset lineage graph to aid in navigating large graphs. You can enable this feature under user settings.
Fixed an issue where the dagster-webserver command was not indicating which port it was using in the command-line output.
Fixed an issue with the quickstart_gcp example wasn’t setting GCP credentials properly when setting up its IOManager.
Fixed an issue where the process output for Dagster run and step containers would repeat each log message twice in JSON format when the process finished.
[ui] Fixed an issue where the config editor failed to load when materializing certain assets.
[auto-materialize] Previously, rematerializing an old partition of an asset which depended on a prior partition of itself would result in a chain of materializations to propagate that change all the way through to the most recent partition of this asset. To prevent these “slow-motion backfills”, this behavior has been updated such that these updates are no longer propagated.
Previously, when importing a dbt project in Cloud, naming the code location “dagster” would cause build failures. This is now disabled and an error is now surfaced.
