1.5.11 / 0.21.11 (libraries)

New

• [ui] Asset graph now displays active filters.
• [ui] Asset graph can now be filtered by compute kind.
• [ui] When backfilling failed and missing partitions of assets, a “Preview” button allows you to see which ranges will be materialized.
• [dagster-dbt] When running DAGSTER_DBT_PARSE_PROJECT_ON_LOAD=1 dagster dev in a new scaffolded project from dagster-dbt project scaffold, dbt logs from creating dbt artifacts to loading the project are now silenced.
• [dagster-airbyte] Added a new connection_meta_to_group_fn argument which allows configuring loaded asset groups based on the connection’s metadata dict.
• [dagster-k8s] Debug information about failed run workers in errors surfaced by run monitoring now includes logs from sidecar containers, not just the main dagster container.

Bugfixes

• The QueuedRunCoordinatorDaemon has been refactored to paginate over runs when applying priority sort and tag concurrency limits. Previously, it loaded all runs into memory causing large memory spikes when many runs were enqueued.
• Callable objects can once again be used to back sensor definitions.
• UPathIOManager has been updated to use the correct path delimiter when interacting with cloud storages from a Windows process.
• In the default multiprocess executor, the STEP_WORKER_STARTED event now fires before importing code in line with the other executors.
• During execution, skipping a step now takes precedence over “abandoning” it due to upstream failure. This is expected to substantially improve the “retry from failure” workflow when conditional branching is in use.
• Fixed an issue where default config values set to EnvVar did not work properly.
• Fixed an issue where resources which implemented IAttachDifferentObjectToOpContext would pass the incorrect object to schedules and sensors.
• Fixed a bug that caused auto-materialize failures when using the materialize_on_cron rule with dynamically partitioned assets.
• Fixed an issue where sensor ticks would sporadically fail with a StopIteration exception.
• [ui] For a job launchpad with a large number of tabs, the “Remove all” option was pushed offscreen. This has been fixed.
• [ui] The asset backfill page now correctly shows backfills that target only unpartitioned assets.
• [ui] Launching an asset job that was defined without_checks no longer fails by attempting to include the checks.
• [dagster-databricks] fix bug that caused crash when polling a submitted job that is still in the Databricks queue (due to concurrency limit).

Community Contributions

• Patched issue where the local compute log path exposed file content outside of the compute log base directory - thanks r1b!
• [dagster-databricks] Added ability to authenticate using an Azure service principal and fix minor bugs involving authenticating with a service principal while DATABRICKS_HOST is set. Thanks @zyd14!

Experimental

• [ui] Dark mode is now available via the User Settings dialog, currently in an experimental state. By default, the app will use a “legacy” theme, closely matching our current colors. A new light mode theme is also available.
• [ui] Asset graph group nodes can be collapsed/expanded by right clicking on the collapsed group node or the header of the expanded group node.
• [ui] Asset graph group nodes can be all collapsed or all expanded by right clicking anywhere on the graph and selecting the appropriate action.
• [ui] The tree view was removed from the asset graph.
• [pipes] PipesLambdaClient, an AWS Lambda pipes client has been added to dagster_aws.
• Fixed a performance regression introduced in the 1.5.10 release where auto-materializing multi-assets became slower.

Documentation

• [getting-started] Added an overview to the Getting Started section that explains the whats and whys of Dagster.
• [pipes] Added a guide for using the new PipesLambdaClient with Dagster Pipes.
• [getting-started] Simplified the Getting Started category. The following pages have been moved:
  • Understanding Dagster project files is now in Guides
  • Telemetry is now in About
• [guides] Fixed a broken link in the Airflow-to-Dagster concept mapping guide.
• [deployment] Cleaned up and updated the Executing with Celery OSS deployment guide.
• [general] Added two guides that were previously missing to the side navigation:
  • Utilizing SCIM provisioning (Deployment > Cloud > Authentication & users > SCIM provisioning)
  • Pandera (Integrations > Pandera)

Dagster Cloud

• When a Dagster Cloud agent starts up, it will now wait to display as Running on the Agents tab in the Dagster Cloud UI until it has launched all the code servers that it needs in order to serve requests.
