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.
