Changelog#

1.9.8 (core) / 0.25.8 (libraries)#

Bugfixes#

  • Fixed a bug with load_assets_from_x functions where we began erroring when a spec and AssetsDefinition had the same key in a given module. We now only error in this case if include_specs=True.
  • [dagster-azure] Fixed a bug in 1.9.6 and 1.9.7 where the default behavior of the compute log manager switched from showing logs in the UI to showing a URL. You can toggle the show_url_only option to True to enable the URL showing behavior.
  • [dagster-dbt] Fixed an issue where group names set on partitioned dbt assets created using the @dbt_assets decorator would be ignored

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

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.
  • [dagster-dbt] Added reference to explain how a dbt manifest can be created at run time or build time.
  • [dagster-dbt] Added reference to outline the steps required to deploy a Dagster and dbt project in CI/CD.
  • Miscellaneous fixes to broken links and typos.
