Changelog#

1.9.6 (core) / 0.25.6 (libraries)#

New#

  • Updated cronitor pin to allow versions >= 5.0.1 to enable use of DayOfWeek as 7. Cronitor 4.0.0 is still disallowed. (Thanks, @joshuataylor!)
  • Added flag checkDbReadyInitContainer to optionally disable db check initContainer.
  • [ui] Added Google Drive icon for kind tags. (Thanks, @dragos-pop!)
  • [ui] Renamed the run lineage sidebar on the Run details page to Re-executions.
  • [ui] Sensors and schedules that appear in the Runs page are now clickable.
  • [ui] Runs targeting assets now show more of the assets in the Runs page.
  • [dagster-airbyte] The destination type for an Airbyte asset is now added as a kind tag for display in the UI.
  • [dagster-gcp] DataprocResource now receives an optional parameter labels to be attached to Dataproc clusters. (Thanks, @thiagoazcampos!)
  • [dagster-k8s] Added a checkDbReadyInitContainer flag to the Dagster Helm chart to allow disabling the default init container behavior. (Thanks, @easontm!)
  • [dagster-k8s] K8s pod logs are now logged when a pod fails. (Thanks, @apetryla!)
  • [dagster-sigma] Introduced build_materialize_workbook_assets_definition which can be used to build assets that run materialize schedules for a Sigma workbook.
  • [dagster-snowflake] SnowflakeResource and SnowflakeIOManager both accept additional_snowflake_connection_args config. This dictionary of arguments will be passed to the snowflake.connector.connect method. This config will be ignored if you are using the sqlalchemy connector.
  • [helm] Added the ability to set user-deployments labels on k8s deployments as well as pods.

Bugfixes#

  • Assets with self dependencies and BackfillPolicy are now evaluated correctly during backfills. Self dependent assets no longer result in serial partition submissions or disregarded upstream dependencies.
  • Previously, the freshness check sensor would not re-evaluate freshness checks if an in-flight run was planning on evaluating that check. Now, the freshness check sensor will kick off an independent run of the check, even if there's already an in flight run, as long as the freshness check can potentially fail.
  • Previously, if the freshness check was in a failing state, the sensor would wait for a run to update the freshness check before re-evaluating. Now, if there's a materialization later than the last evaluation of the freshness check and no planned evaluation, we will re-evaluate the freshness check automatically.
  • [ui] Fixed run log streaming for runs with a large volume of logs.
  • [ui] Fixed a bug in the Backfill Preview where a loading spinner would spin forever if an asset had no valid partitions targeted by the backfill.
  • [dagster-aws] PipesCloudWatchMessageReader correctly identifies streams which are not ready yet and doesn't fail on ThrottlingException. (Thanks, @jenkoian!)
  • [dagster-fivetran] Column metadata can now be fetched for Fivetran assets using FivetranWorkspace.sync_and_poll(...).fetch_column_metadata().
  • [dagster-k8s] The k8s client now waits for the main container to be ready instead of only waiting for sidecar init containers. (Thanks, @OrenLederman!)

Documentation#

  • Fixed a typo in the dlt_assets API docs. (Thanks, @zilto!)

1.9.5 (core) / 0.25.5 (libraries)#

New#

  • The automatic run retry daemon has been updated so that there is a single source of truth for if a run will be retried and if the retry has been launched. Tags are now added to run at failure time indicating if the run will be retried by the automatic retry system. Once the automatic retry has been launched, the run ID of the retry is added to the original run.
  • When canceling a backfill of a job, the backfill daemon will now cancel all runs launched by that backfill before marking the backfill as canceled.
  • Dagster execution info (tags such as dagster/run-id, dagster/code-location, dagster/user and Dagster Cloud environment variables) typically attached to external resources are now available under DagsterRun.dagster_execution_info.
  • SensorReturnTypesUnion is now exported for typing the output of sensor functions.
  • [dagster-dbt] dbt seeds now get a valid code version (Thanks @marijncv!).
  • Manual and automatic retries of runs launched by backfills that occur while the backfill is still in progress are now incorporated into the backfill's status.
  • Manual retries of runs launched by backfills are no longer considered part of the backfill if the backfill is complete when the retry is launched.
  • [dagster-fivetran] Fivetran assets can now be materialized using the FivetranWorkspace.sync_and_poll(…) method in the definition of a @fivetran_assets decorator.
  • [dagster-fivetran] load_fivetran_asset_specs has been updated to accept an instance of DagsterFivetranTranslator or custom subclass.
  • [dagster-fivetran] The fivetran_assets decorator was added. It can be used with the FivetranWorkspace resource and DagsterFivetranTranslator translator to load Fivetran tables for a given connector as assets in Dagster. The build_fivetran_assets_definitions factory can be used to create assets for all the connectors in your Fivetran workspace.
  • [dagster-aws] ECSPipesClient.run now waits up to 70 days for tasks completion (waiter parameters are configurable) (Thanks @jenkoian!)
  • [dagster-dbt] Update dagster-dbt scaffold template to be compatible with uv (Thanks @wingyplus!).
  • [dagster-airbyte] A load_airbyte_cloud_asset_specs function has been added. It can be used with the AirbyteCloudWorkspace resource and DagsterAirbyteTranslator translator to load your Airbyte Cloud connection streams as external assets in Dagster.
  • [ui] Add an icon for the icechunk kind.
  • [ui] Improved ui for manual sensor/schedule evaluation.

Bugfixes#

  • Fixed database locking bug for the ConsolidatedSqliteEventLogStorage, which is mostly used for tests.

  • [ui] Fix global auto-materialize tick timeline when paginating.

1.9.4 (core) / 0.25.4 (libraries)#

New#

  • Global op concurrency is now enabled on the default SQLite storage. Deployments that have not been migrated since 1.6.0 may need to run dagster instance migrate to enable.
  • Introduced map_asset_specs to enable modifying AssetSpecs and AssetsDefinitions in bulk.
  • Introduced AssetSpec.replace_attributes and AssetSpec.merge_attributes to easily alter properties of an asset spec.
  • [ui] Add a "View logs" button to open tick logs in the sensor tick history table.
  • [ui] Add Spanner kind icon.
  • [ui] The asset catalog now supports filtering using the asset selection syntax.
  • [dagster-pipes, dagster-aws] PipesS3MessageReader now has a new parameter include_stdio_in_messages which enables log forwarding to Dagster via Pipes messages.
  • [dagster-pipes] Experimental: A new Dagster Pipes message type log_external_stream has been added. It can be used to forward external logs to Dagster via Pipes messages.
  • [dagster-powerbi] Opts in to using admin scan APIs to pull data from a Power BI instance. This can be disabled by passing load_powerbi_asset_specs(..., use_workspace_scan=False).
  • [dagster-sigma] Introduced an experimental dagster-sigma snapshot command, allowing Sigma workspaces to be captured to a file for faster subsequent loading.

Bugfixes#

  • Fixed a bug that caused DagsterExecutionStepNotFoundError errors when trying to execute an asset check step of a run launched by a backfill.
  • Fixed an issue where invalid cron strings like "0 0 30 2 *" that represented invalid dates in February were still allowed as Dagster cron strings, but then failed during schedule execution. Now, these invalid cronstrings will raise an exception when they are first loaded.
  • Fixed a bug where owners added to AssetOuts when defining a @graph_multi_asset were not added to the underlying AssetsDefinition.
  • Fixed a bug where using the & or | operators on AutomationConditions with labels would cause that label to be erased.

0.12.14#

Community Contributions#

  • Updated click version, thanks @ashwin153!
  • Typo fix, thanks @geoHeil!

Bugfixes#

  • Fixed a bug in dagster_aws.s3.sensor.get_s3_keys that would return no keys if an invalid s3 key was provided
  • Fixed a bug with capturing python logs where statements of the form my_log.info("foo %s", "bar") would cause errors in some scenarios.
  • Fixed a bug where the scheduler would sometimes hang during fall Daylight Savings Time transitions when Pendulum 2 was installed.

Experimental#

  • Dagit now uses an asset graph to represent jobs built using build_assets_job. The asset graph shows each node in the job’s graph with metadata about the asset it corresponds to - including asset materializations. It also contains links to upstream jobs that produce assets consumed by the job, as well as downstream jobs that consume assets produced by the job.
  • Fixed a bug in load_assets_from_dbt_project and load_assets_from_dbt_project that would cause runs to fail if no runtime_metadata_fn argument were supplied.
  • Fixed a bug that caused @asset not to infer the type of inputs and outputs from type annotations of the decorated function.
  • @asset now accepts a compute_kind argument. You can supply values like “spark”, “pandas”, or “dbt”, and see them represented as a badge on the asset in the Dagit asset graph.

0.12.13#

Community Contributions#

  • Changed VersionStrategy.get_solid_version and VersionStrategy.get_resource_version to take in a SolidVersionContext and ResourceVersionContext, respectively. This gives VersionStrategy access to the config (in addition to the definition object) when determining the code version for memoization. (Thanks @RBrossard!).

    Note: This is a breaking change for anyone using the experimental VersionStrategy API. Instead of directly being passed solid_def and resource_def, you should access them off of the context object using context.solid_def and context.resource_def respectively.

New#

  • [dagster-k8s] When launching a pipeline using the K8sRunLauncher or k8s_job_executor, you can know specify a list of volumes to be mounted in the created pod. See the API docs for for information.
  • [dagster-k8s] When specifying a list of environment variables to be included in a pod using custom configuration, you can now specify the full set of parameters allowed by a V1EnvVar in Kubernetes.

Bugfixes#

  • Fixed a bug where mapping inputs through nested composite solids incorrectly caused validation errors.
  • Fixed a bug in Dagit, where WebSocket reconnections sometimes led to logs being duplicated on the Run page.
  • Fixed a bug In Dagit, where log views that were scrolled all the way down would not auto-scroll as new logs came in.

Documentation#

0.12.12#

Community Contributions#

  • [dagster-msteams] Introduced a new integration with Microsoft Teams, which includes a connection resource and support for sending messages to Microsoft Teams. See details in the API Docs (thanks @iswariyam!).
  • Fixed a mistake in the sensors docs (thanks @vitorbaptista)!

Bugfixes#

  • Fixed a bug that caused run status sensors to sometimes repeatedly fire alerts.
  • Fixed a bug that caused the emr_pyspark_step_launcher to fail when stderr included non-Log4J-formatted lines.
  • Fixed a bug that caused applyPerUniqueValue config on the QueuedRunCoordinator to fail Helm schema validation.
  • [dagster-shell] Fixed an issue where a failure while executing a shell command sometimes didn’t raise a clear explanation for the failure.

Experimental#

  • Added experimental @asset decorator and build_assets_job APIs to construct asset-based jobs, along with Dagit support.
  • Added load_assets_from_dbt_project and load_assets_from_dbt_manifest, which enable constructing asset-based jobs from DBT models.

0.12.11#

Community Contributions#

  • [helm] The ingress now supports TLS (thanks @cpmoser!)
  • [helm] Fixed an issue where dagit could not be configured with an empty workspace (thanks @yamrzou!)

New#

  • [dagstermill] You can now have more precise IO control over the output notebooks by specifying output_notebook_name in define_dagstermill_solid and providing your own IO manager via "output_notebook_io_manager" resource key.

  • We've deprecated output_notebook argument in define_dagstermill_solid in favor of output_notebook_name.

  • Previously, the output notebook functionality requires “file_manager“ resource and result in a FileHandle output. Now, when specifying output_notebook_name, it requires "output_notebook_io_manager" resource and results in a bytes output.

  • You can now customize your own "output_notebook_io_manager" by extending OutputNotebookIOManager. A built-in local_output_notebook_io_manager is provided for handling local output notebook materialization.

  • See detailed migration guide in https://github.com/dagster-io/dagster/pull/4490.

  • Dagit fonts have been updated.

Bugfixes#

  • Fixed a bug where log messages of the form context.log.info("foo %s", "bar") would not get formatted as expected.
  • Fixed a bug that caused the QueuedRunCoordinator’s tag_concurrency_limits to not be respected in some cases
  • When loading a Run with a large volume of logs in Dagit, a loading state is shown while logs are retrieved, clarifying the loading experience and improving render performance of the Gantt chart.
  • Using solid selection with pipelines containing dynamic outputs no longer causes unexpected errors.

Experimental#

  • You can now set tags on a graph by passing in a dictionary to the tags argument of the @graph decorator or GraphDefinition constructor. These tags will be set on any runs of jobs are built from invoking to_job on the graph.
  • You can now set separate images per solid when using the k8s_job_executor or celery_k8s_job_executor. Use the key image inside the container_config block of the k8s solid tag.
  • You can now target multiple jobs with a single sensor, by using the jobs argument. Each RunRequest emitted from a multi-job sensor’s evaluation function must specify a job_name.

0.12.10#

Community Contributions#

  • [helm] The KubernetesRunLauncher image pull policy is now configurable in a separate field (thanks @yamrzou!).
  • The dagster-github package is now usable for GitHub Enterprise users (thanks @metinsenturk!) A hostname can now be provided via config to the dagster-github resource with the key github_hostname:
execute_pipeline(
      github_pipeline, {'resources': {'github': {'config': {
           "github_app_id": os.getenv('GITHUB_APP_ID'),
           "github_app_private_rsa_key": os.getenv('GITHUB_PRIVATE_KEY'),
           "github_installation_id": os.getenv('GITHUB_INSTALLATION_ID'),
           "github_hostname": os.getenv('GITHUB_HOSTNAME'),
      }}}}
)

New#

  • Added a database index over the event log to improve the performance of pipeline_failure_sensor and run_status_sensor queries. To take advantage of these performance gains, run a schema migration with the CLI command: dagster instance migrate.

Bugfixes#

  • Performance improvements have been made to allow dagit to more gracefully load a run that has a large number of events.
  • Fixed an issue where DockerRunLauncher would raise an exception when no networks were specified in its configuration.

Breaking Changes#

  • dagster-slack has migrated off of deprecated slackclient (deprecated) and now uses [slack_sdk](https://slack.dev/python-slack-sdk/v3-migration/).

Experimental#

  • OpDefinition, the replacement for SolidDefinition which is the type produced by the @op decorator, is now part of the public API.
  • The daily_partitioned_config, hourly_partitioned_config, weekly_partitioned_config, and monthly_partitioned_config now accept an end_offset parameter, which allows extending the set of partitions so that the last partition ends after the current time.
