Changelog#

1.4.17 / 0.20.17 (libraries)#

New#

  • [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.

Bugfixes#

  • 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.

Experimental#

  • 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.

Documentation#

  • 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.

1.4.16 / 0.20.16 (libraries)#

New#

  • [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.

Bugfixes#

  • 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.

Deprecations#

  • Deprecated ExpectationResult. This will be made irrelevant by upcoming data quality features.

Community Contributions#

  • Enabled chunked backfill runs to target more than one asset, thanks @ruizh22!

Experimental#

  • Users can now emit arbitrary asset materializations, observations, and asset check evaluations from sensors via SensorResult.

1.4.15 / 0.20.15 (libraries)#

New#

  • 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.

Bugfixes#

  • 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.

Experimental#

  • MaterializeResult has been added as a new return type to be used in @asset / @multi_asset materialization functions
  • [ui] The auto-materialize page now properly indicates that the feature is experimental and links to our documentation.

Documentation#

  • The Concepts category page got a small facelift, to bring it line with how the side navigation is organized.

Dagster Cloud#

  • 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.

1.4.14 / 0.20.14 (libraries)#

New#

  • Added a new tooltip to asset runs to either view the asset list or lineage

Bugfixes#

  • [ui] Fixed an issue where re-executing a run from a particular run's page wouldn’t navigate to the newly created run

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.
  • [asset checks] Added an ‘execute’ button to run checks without materializing the asset. Currently this is only supported for checks defined with @asset_check or AssetChecksDefinition.
  • [asset checks] Added check_specs argument to @graph_multi_asset
  • [asset checks] Fixed a bug with checks on @graph_asset that would raise an error about nonexistant checks

1.4.13 / 0.20.13 (libraries)#

New#

  • OpExecutionContext.add_output_metadata can now be called multiple times per output.

Bugfixes#

  • The double evaluation of log messages in sensor logging has been fixed (thanks @janosroden !)
  • 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!)
  • [dagster-dbt] Fixed an issue where DagsterDbtTranslator did not properly invoke get_auto_materialize_policy and get_freshness_policy for load_assets_from_dbt_project.
  • [ui] Fixed a number of interaction bugs with the Launchpad config editor, including issues with newlines and multiple cursors.
  • [ui] Asset keys and partitions presented in the asset checks UI are sorted to avoid flickering.
  • [ui] Backfill actions (terminate backfill runs, cancel backfill submission) are now available from an actions menu on the asset backfill details page.

Community Contributions#

  • Typo fix in run monitoring docs (thanks c0dk)!
  • Grammar fixes in testing docs (thanks sonnyarora)!
  • Typo fix in contribution docs (thanks tab1tha)!

Experimental#

  • [dagster-dbt][asset checks] Added support to model dbt tests as Dagster asset checks.
  • [asset checks] Added @graph_asset support. This can be used to implement blocking checks, by raising an exception if the check fails.
  • [asset checks] Fixed @multi_asset subsetting, so only checks which target assets in the subset will execute.
  • [asset checks] AssetCheckSpecs will now cause an error at definition time if they target an asset other than the one they’re defined on.
  • [asset checks] The status of asset checks now appears in the asset graph and asset graph sidebar.

Dagster Cloud#

  • [Experimental] Added support for freeing global op concurrency slots after runs have finished, using the deployment setting: run_monitoring > free_slots_after_run_end_seconds
