1.5.6 / 0.21.6 (libraries)

New

• [dagster-k8s] The PipesK8sClient will now attempt to load the appropriate kubernetes config, and exposes arguments for controlling this process.
• [ui] The launch asset backfill modal now offers a preview dialog showing the targeted asset partitions and their backfill policies when partition mapping or varying backfill policies are present.
• [asset-checks] New load_asset_checks_from_modules functions for loading asset checks in tandem with load_assets_from_modules.
• Previously, the daemon process would terminate with an error if it believed that a thread might be hanging, which sometimes caused undesirable terminations when doing large backfills or auto-materializing many assets. Now, the daemon process will emit a warning instead of terminate.
• [dagster-dbt] dagster-dbt project scaffold now uses ~/.dbt/profiles.yml if a profiles.yml is not present in the dbt project directory.
• [dagster-dbt] @dbt_assets now support PartitionMapping using DagsterDbtTranslator.get_partition_mapping.
• [dagster-dbt] Self dependencies can now be enabled for dbt models that are represented by @dbt_assets. To enable this, add the following metadata to your dbt model’s metadata in your dbt project:

meta:
  dagster:
    has_self_dependency: True

Bugfixes

• Fixed an issue where Dagster imports would throw errors when using pydantic<2.0.0 but having pydantic-core installed.
• Previously, asset backfills that targeted partitioned assets with a LastPartitionMapping dependency would raise an error. This has been fixed.
• Fixed a multipartitions partition mapping bug where a instance is not available to load partitions error was raised.
• [asset-checks] Fixed an issue with conflicting op names when using build_asset_with_blocking_check
• [ui] Viewing run logs containing very large messages no longer causes the UI to crash in Safari on macOS
• [ui] Drilling into the graph of a graph-backed asset with 4+ inputs or outputs no longer causes the asset graph to crash with a rendering error.
• [ui] On the backfill details page, clicking to a specific asset correctly shows the partitions that were materialized for that asset when partition mapping is in use.
• [ui] The Asset > Partition page now loads partition details more quickly in cases where calculating the staleness of the partition took a significant amount of time.
• Fixed a bug introduced in 1.5.0 where instances that haven’t been migrated to the latest schema hit an error upon run deletion.
• [auto-materialize] Previously, if an asset partition was skipped on a tick for one reason, and then processed and skipped on a later tick for an additional reason, only the most recent skip reason would be tracked. Now, all skip reasons are tracked.
• [dagster-dbt] Fixed an issue where if an exclude that didn’t match any dbt nodes was used in @dbt_assets, an error would be raised. The error is now properly handled.
• [dagster-dbt] When invoking DbtCliResource.cli(...) in an op, AssetMaterialization's instead of Output are now emitted.

Experimental

• Global op concurrency slots are now released in between retries of op execution failures.

Documentation

• Updated the tutorial to reflect best practices and APIs as of Dagster 1.5

Dagster Cloud

• The report_asset_observation REST endpoint for reporting runless events is now available.
