Changelog#

1.4.5 / 0.20.5 (libraries)#

New#

  • @graph_asset now takes a config parameter equivalent to the parameter on @graph.
  • Added an optional dynamic_partitions_store argument to DynamicPartitionsDefinition for multi-partition run properly with dynamic partitions (Thanks @elzzz!).
  • [dagster-grpahql] Added partitionsByAssets to backfillParams for ranged partition backfill (Thanks @ruizh22!).
  • [dagster-dbt] Support for dbt-core==1.6 has been added.
  • [dagster-dbt] DbtCliResource now supports configuring profiles_dir.
  • [dagster-k8s] Allow specifying restart_policy on k8s_job_op (Thanks @Taadas!).
  • [dagster-snowflake] Added authenticator to SnowflakePandasIOManager, which allows specifying the authentication mechanism to use (Thanks @pengw0048!).
  • [ui] The Asset > Events page now allows you to filter by event type, making it easy to hide observations.
  • [ui] The Asset > Partitions page checks to see if the selected partition is stale and displays stale causes in the details pane.
  • [ui] Hovering over "Fresh" tags now provides detailed information about why the last materialization meets the asset's freshness policy.
  • [ui] The global asset graph can now be filtered to display a subset of the available asset groups.

Bugfixes#

  • In some situations, multiple materializations of the same asset could be kicked off when using a lazy AutoMaterializePolicy with assets that had at least one source asset parent and at least one non-source asset parent. This has been fixed.
  • After applying an eager AutoMaterializePolicy to a time-partitioned asset downstream of an unpartitioned asset, the latest partition would only ever be materialized a single time, rather than updating in response to any parent updates. This has been fixed.
  • Fixed an issue that would cause the creation of a StaticPartitionsDefinition containing many thousands of partitions could take a significant amount of time.
  • The run coordinator daemon now uses a fresh request context on each iteration, fixing an issue where stale grpc server references could be used in certain high volume conditions.
  • Automatically generated data versions for partitioned assets now correctly reflect the data versions of upstream partitions. Previously, they were computed using the data versions from the most recent materializations of upstream assets regardless of partition.
  • [dagster-airbyte] Previously, attempting to load assets from an Airbyte instance in which some of the tables had hyphens in their name would result in an error. This has been fixed.
  • [dagster-dbt] Previously, attempting to load assets from a dbt project in which some of the models had hyphens in their name would result in an error. This has been fixed.
  • [dagstermill] Fixed a bug where known state for executing dagstermill ops was not correctly passed in (Thanks @motuzov!).
  • [ui] Pressing the up or down arrow key without a selection in the asset graph no longer causes a page error.

Documentation#

  • Added the starter project’s template for Dagster University.
  • Fixed an incorrect method name in DagsterDbtTranslator Docs (Thanks @akan72!).

Dagster Cloud#

  • When importing a dbt project on the Dagster Cloud setup page, an Unexpected exception error would be raised when scaffolding a pull request on a repository with no profiles.yml. This behavior has been updated to raise a more descriptive error message on the repo selection page.
  • The running multiple agents guide has been revamped to discuss running agent replicas and zero-downtime deployment of the agent.
  • The agentReplicas config setting on the helm chart has been renamed to isolatedAgents. In order to use this config setting, your user code dagster version needs to be 1.4.3 or greater.

1.4.4 / 0.20.4 (libraries)#

New#

  • [ui] When viewing a run for auto-materialized assets, show a tag with information about the assets that were materialized.
  • [ui] In the Auto-materialize History view, when one or more of an asset’s parents have been updated, the set of updated parents will be viewable.
  • [ui] Link to the auto-materialized history for an asset from the asset DAG view.
  • [ui] For runs that were the result of auto-observation, show a tag for this in the Runs list view.
  • Added warnings for storage incompatibility with the experimental global op concurrency.

Bugfixes#

  • [dagster-dbt] Fixed an issue where dagster-dbt project scaffold didn’t create a project directory with all the scaffolded files.
  • Fixed an issue which could cause errors when using the SpecificPartitionsPartitionMapping with auto-materialization.

Breaking Change#

  • Previously, it was possible to set max_materializations_per_minute on an AutoMaterializePolicy to a non-positive number. This will now result in an error.

Community Contributions#

  • Fix for loading multipartitions paths in upath_io_manager from @harrylojames; thank you!
  • Docs typo fix from @C0DK; thank you!

Documentation#

  • Revamped the dagster-dbt tutorial to take advantage of dagster project scaffold and the new dagster-dbt APIs.

1.4.3 / 0.20.3 (libraries)#

New#

  • [dagster-dbt] When invokingdagster-dbt project scaffold on a dbt project directory, if a profiles.yml exists in the root of the directory, its contents are used to add dbt adapter packages to the scaffolded setup.py.
  • The default sentinel value for the multiprocessing executor’s max_concurrent field has been changed from 0 to None to more clearly signal its intent. A value of 0 is still interpreted as the sentinel value which dynamically allocates max_concurrent based on detected CPU count.

Bugfixes#

  • IO managers defined on jobs will now be properly merged with resources defined in Definitions, so that jobs are able to override the IO manager used.
  • [dagster-fivetran] Fixed an issue where EnvVars in a FivetranResource would not be evaluated when loading assets from the Fivetran instance.
  • [dagster-airbyte] Fixed an issue where EnvVars in an AirbyteResource would not be evaluated when loading assets from the Airbyte resource.

Documentation#

  • [dagster-dbt] Added API docs for DbtCliResource, DbtCliInvocation, @dbt_assets, DagsterDbtTranslator, dagster-dbt project scaffold
  • [dagster-dbt] Expanded references for new APIs:
    • Added documentation to customize asset definition attributes for dbt assets
    • Added documentation to define upstream and downstream dependencies to dbt assets
    • Added documentation to define schedules for dbt assets

Dagster Cloud#

  • The experimental agent config setting agent_replicashas been deprecated in favor of a new name isolated_agents (agentReplicas --> isolatedAgents in the helm chart). Upgrading to the new name requires all code locations to be on 1.4.3 or greater.

1.4.2 / 0.20.2 (libraries)#

Bugfixes#

  • Fixes a bug in dagster-dbt that was preventing it from correctly materializing subselections of dbt asset.

1.4.1 / 0.20.1 (libraries)#

Bugfixes#

  • Fixes a bug in dagster-dbt that was preventing it efficiently loading dbt projects from a manifest.
