Changelog#

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.
  • [ui] Fix stretched tags in backfill table view for non-partitioned assets.
  • [ui] Open automation sensor evaluation details in a dialog instead of navigating away.
  • [ui] Fix scrollbars in dark mode.
  • [dagster-sigma] Workbooks filtered using a SigmaFilter no longer fetch lineage information.
  • [dagster-powerbi] Fixed an issue where reports without an upstream dataset dependency would fail to translate to an asset spec.

  • [dagster-dbt] DbtProject is adopted and no longer experimental. Using DbtProject helps achieve a setup where the dbt manifest file and dbt dependencies are available and up-to-date, during development and in production. Check out the API docs for more: https://docs.dagster.io/_apidocs/libraries/dagster-dbt#dagster_dbt.DbtProject.

  • [experimental] Introduced the ability to attach code references to your assets, which allow you to view source code for an asset in your editor or in git source control. For more information, see the code references docs: https://docs.dagster.io/guides/dagster/code-references.
  • [ui] Performance improvements to loading the asset overview tab.
  • [ui] Performance improvements for rendering gantt charts with 1000’s of ops/steps.

  • For subselections of graph-backed multi-assets, there are some situations where we used to unnecessarily execute some of the non-selected assets. Now, we no longer execute them in those situations. There are also some situations where we would skip execution of some ops that might be needed. More information on the particulars is available here.
  • Fixed the @graph_asset decorator overload missing an owners argument, thanks @askvinni!
  • Fixed behavior of passing custom image config to the K8sRunLauncher, thanks @marchinho11!
  • [dagster-dbt] Fixed an issue with emitting column lineage when using BigQuery.

  • [dagster-fivetran] Fixed an issue where the Fivetran connector resource would sometimes hang if there was a networking issue while connecting to the Fivetran API.
  • [dagster-aws] Fixed an issue where the EMR step launcher would sometimes fail due to multiple versions of the dateutil package being installed in the default EMR python evnrionment.
  • [ui] The “Create date” column in the runs table now correctly shows the time at which a run was created instead of the time when it started to execute.
  • [ui] Fixed dark mode colors in run partitions graphs.
  • [auto-materialize] Fixed an issue which could cause errors in the AutoMaterializeRule.skip_on_parent_missing rule when a parent asset had its PartitionsDefinition changed.
  • [declarative-automation] Fixed an issue which could cause errors when viewing the evaluation history of assets with AutomationConditions.
  • [declarative-automation] Previously, AutomationCondition.newly_updated() would trigger on any ASSET_OBSERVATION event. Now, it only triggers when the data version on that event changes.

Breaking Changes#

  • [dagster-dbt] The cli command dagster-dbt project prepare-for-deployment has been replaced by dagster-dbt project prepare-and-package.
  • [dagster-dbt] During development,DbtProject no longer prepares the dbt manifest file and dbt dependencies in its constructor during initialization. This process has been moved to prepare_if_dev(), that can be called on the DbtProject instance after initialization. Check out the API docs for more: https://docs.dagster.io/_apidocs/libraries/dagster-dbt#dagster_dbt.DbtProject.prepare_if_dev.
