1.3.14 (core) / 0.19.14 (libraries)

New

• DynamicPartitionsDefinition and SensorResult are no longer marked experimental
• DagsterInstance now has a get_status_by_partition method, which returns the status of each partition for a given asset. Thanks renzhe-brian!
• DagsterInstance now has a get_latest_materialization_code_versions method, which returns the code version of the latest materialization for each of the provided (non-partitioned) assets.
• The error message for when an asset illegally depends on itself is now more informative.
• Further performance improvements for the Asset Daemon.
• Performance improvements in the asset graph view for large asset graphs.
• Pandas 2.x is now supported in all dagster packages.
• build_asset_context has been added as an asset focused replacement for build_op_context.
• build_op_context now accepts a partition_key_range parameter.
• New AssetSelection.upstream_source_assets method allows selecting source assets upstream of the current selection.
• AssetSelection.key_prefixes and AssetSelection.groups now accept an optional include_sources parameter.
• The AutoMaterialize evaluations UI now provides more details about partitions and waiting on upstream assets.
• [dbt] The DbtCli resource is no longer marked experimental.
• [dbt] The global_config parameter of the DbtCli resource has been renamed to global_config_flags
• [dbt] load_assets_from_dbt_project and load_assets_from_dbt_manifest now work with the DbtCli resource.
• [dbt] The manifest argument of the @dbt_assets decorator now additionally can accept a Path argument representing a path to the manifest file or dictionary argument representing the raw manifest blob.
• [dbt] When invoking DbtCli.cli from inside a @dbt_assets-decorated function, you no longer need to supply the manifest argument as long as you provide the context argument.
• [dbt] The DbtManifest object can now generate schedules using dbt selection syntax.

dbt_manifest.build_schedule(
      job_name="materialize_dbt_models",
      cron_schedule="0 0 * * *",
      dbt_select="fqn:*"
  )

• [dbt] When invoking DbtCli.cli and the underlying command fails, an exception will now be raised. To suppress the exception, run the DbtCli.cli(..., raise_on_error=False).
• [ui] You can now alphabetically sort your partitions on the asset partitions page
• [ui] A button in the “Run is materializing this asset” and “Run failed to materialize this asset” banners provides direct access to the relevant run logs

Bugfixes

• Fixed a bug that caused asset metadata to not be available available on the OutputContext when using with_attributes or AssetsDefinition.from_graph.
• Previously, if a partitioned asset at the root of the graph had more missing partitions than its AutoMaterializePolicy’s max_materializations_per_minute parameter, those older partitions would not be properly discarded from consideration on subsequent ticks. This has been fixed.
• Fixed a bug that caused AutoMaterializePolicy.lazy() to not materialize missing assets that were downstream of assets without an AutoMaterializePolicy.
• In rare cases, the AssetDaemon could hit an exception when using a combination of freshness policies and observable source assets. This has been fixed.
• Previously, string type annotations (most commonly via modules containing from __future__ import annotations) would cause errors in most cases when used with Dagster definitions. This has been fixed for the vast majority of cases.
• AssetExecutionContext has returned to being a type alias for OpExecutionContext.
• [ui] Date filtering on the runs page now takes your timezone into consideration
• [ui] Fixed a bug where selecting partitions in the launchpad dialog cleared out your configuration
• [ui] In the run Gantt chart, executed steps that follow skipped steps no longer render off the far right of the visualization.
• [ui] Cancelling a running backfill no longer makes canceled partitions un-selectable on the job partitions page and backfill modal, and cancellation is shown in gray instead of red.

Breaking Changes

• [experimental] The internal time_window_partition_scope_minutes parameter of the AutoMaterializePolicy class has been removed. Instead, max_materializations_per_minute should be used to limit the number of runs that may be kicked off for a partitioned asset.

Deprecations

• [dbt] DbtCliResource has been deprecated in favor of DbtCli.
• The python package dagit has been deprecated in favor of a new package dagster-webserver.
• OpExecutionContext.asset_partition_key_range has been deprecated in favor of partition_key_range.

Community Contributions

• The databricks_pyspark_step_launcher will no longer error when executing steps that target a single partition of a DynamicPartitionsDefinition (thanks @weberdavid!).
• Increased timeout on readinessProbe for example user code images, which prevents breakages in certain scenarios (thanks @leehuwuj)!
• Avoid creation of erroneous local directories by GCS IO manager (thanks @peterjclaw)!
• Fixed typo in intro docs (thanks @adeboyed)!
• Fix typo in bigquery docs (thanks @nigelainscoe)!
• Fix typing on run tag validation (thanks @yuvalgimmunai)!
• Allow passing repositoryCredentials arn as config to ecs run launcher (thanks @armandobelardo)!

Experimental

• The @observable_source_asset decorator now accepts an auto_observe_interval_minutes parameter. If the asset daemon is turned on, then the observation function will automatically be run at this interval.
• [dbt] DbtCliTask has been renamed to DbtCliInvocation
• [dbt] The get_asset_key_by_output_name and get_node_info_by_output_name methods of DbtManifest have been renamed toget_asset_key_for_output_name and get_node_info_for_output_name, respectively.
• [ui] A new feature flag allows you to switch Asset DAG rendering to a tighter horizontal layout, which may be preferable in some scenarios

Documentation

• Many public methods that were missing in the API docs are now documented. Updated classes include DagsterInstance, *MetadataValue, DagsterType, and others.
• dagster-pandera now has an API docs page.
• Deprecated methods in the API docs now are marked with a special badge.
