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.
  • [dagster-aws] Fixed a bug in the ECSRunLauncher that prevented it from accepting a user-provided task definition when DAGSTER_CURRENT_IMAGE was not set in the code location.
  • [ui] Fixed an issue that would sometimes cause the asset graph to fail to render on initial load.
  • [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.
  • [ui] Launching partitioned asset jobs from the launchpad now warns if no partition is selected.
  • [ui] Fixed unnecessary middle truncation occurring in dialogs.
  • [ui] Fixed timestamp labels and "Now" line rendering bugs on the sensor tick timeline.

0.9.4#

Breaking Changes

  • When using the configured API on a solid or composite solid, a new solid name must be provided.
  • The image used by the K8sScheduler to launch scheduled executions is now specified under the “scheduler” section of the Helm chart (previously under “pipeline_run” section).

New

  • Added an experimental mode that speeds up interactions in dagit by launching a gRPC server on startup for each repository location in your workspace. To enable it, add the following to your dagster.yaml:
opt_in:
  local_servers: true
  • Intermediate Storage and System Storage now default to the first provided storage definition when no configuration is provided. Previously, it would be necessary to provide a run config for storage whenever providing custom storage definitions, even if that storage required no run configuration. Now, if the first provided storage definition requires no run configuration, the system will default to using it.
  • Added a timezone picker to Dagit, and made all timestamps timezone-aware
  • Added solid_config to hook context which provides the access to the config schema variable of the corresponding solid.
  • Hooks can be directly set on PipelineDefinition or @pipeline, e.g. @pipeline(hook_defs={hook_a}). It will apply the hooks on every single solid instance within the pipeline.
  • Added Partitions tab for partitioned pipelines, with new backfill selector.

0.9.3#

Breaking Changes

  • Removed deprecated --env flag from CLI
  • The --host CLI param has been renamed to --grpc_host to avoid conflict with the dagit --host param.

New

  • Descriptions for solid inputs and outputs will now be inferred from doc blocks if available (thanks @AndersonReyes !)
  • Various documentation improvements (thanks @jeriscc !)
  • Load inputs from pyspark dataframes (thanks @davidkatz-il !)
  • Added step-level run history for partitioned schedules on the schedule view
  • Added great_expectations integration, through the dagster_ge library. Example usage is under a new example, called ge_example, and documentation for the library can be found under the libraries section of the api docs.
  • PythonObjectDagsterType can now take a tuple of types as well as a single type, more closely mirroring isinstance and allowing Union types to be represented in Dagster.
  • The configured API can now be used on all definition types (including CompositeDefinition). Example usage has been updated in the configuration documentation.
  • Updated Helm chart to include auto-generated user code configmap in user code deployment by default

Bugfixes

  • Databricks now checks intermediate storage instead of system storage
  • Fixes a bug where applying hooks on a pipeline with composite solids would flatten the top-level solids. Now applying hooks on pipelines or composite solids means attaching hooks to every single solid instance within the pipeline or the composite solid.
  • Fixes the GraphQL playground hosted by dagit
  • Fixes a bug where K8s CronJobs were stopped unnecessarily during schedule reconciliation

Experimental

  • New dagster-k8s/config tag that lets users pass in custom configuration to the Kubernetes Job, Job metadata, JobSpec, PodSpec, and PodTemplateSpec metadata.
    • This allows users to specify settings like eviction policy annotations and node affinities.
    • Example:
      @solid(
        tags = {
          'dagster-k8s/config': {
            'container_config': {
              'resources': {
                'requests': { 'cpu': '250m', 'memory': '64Mi' },
                'limits': { 'cpu': '500m', 'memory': '2560Mi' },
              }
            },
            'pod_template_spec_metadata': {
              'annotations': { "cluster-autoscaler.kubernetes.io/safe-to-evict": "true"}
            },
            'pod_spec_config': {
              'affinity': {
                'nodeAffinity': {
                  'requiredDuringSchedulingIgnoredDuringExecution': {
                    'nodeSelectorTerms': [{
                      'matchExpressions': [{
                        'key': 'beta.kubernetes.io/os', 'operator': 'In', 'values': ['windows', 'linux'],
                      }]
                    }]
                  }
                }
              }
            },
          },
        },
      )
      def my_solid(context):
        context.log.info('running')
    

0.9.2#

Breaking Changes

  • The --env flag no longer works for the pipeline launch or pipeline execute commands. Use --config instead.
  • The pipeline execute command no longer accepts the --workspace argument. To execute pipelines in a workspace, use pipeline launch instead.

New

  • Added ResourceDefinition.mock_resource helper for magic mocking resources. Example usage can be found here
  • Remove the row_count metadata entry from the Dask DataFrame type check (thanks @kinghuang!)
  • Add orient to the config options when materializing a Dask DataFrame to json (thanks @kinghuang!)

Bugfixes

  • Fixed a bug where applying configured to a solid definition would overwrite inputs from run config.
  • Fixed a bug where pipeline tags would not apply to solid subsets.
  • Improved error messages for repository-loading errors in CLI commands.
  • Fixed a bug where pipeline execution error messages were not being surfaced in Dagit.

0.9.1#

Bugfixes

  • Fixes an issue in the dagster-k8s-celery executor when executing solid subsets

Breaking Changes

  • Deprecated the IntermediateStore API. IntermediateStorage now wraps an ObjectStore, and TypeStoragePlugin now accepts an IntermediateStorage instance instead of an IntermediateStore instance. (Noe that IntermediateStore and IntermediateStorage are both internal APIs that are used in some non-core libraries).

0.9.0 “Laundry Service”#

Breaking Changes

  • The dagit key is no longer part of the instance configuration schema and must be removed from dagster.yaml files before they can be used.
  • -d can no longer be used as a command-line argument to specify a mode. Use --mode instead.
  • Use --preset instead of --preset-name to specify a preset to the pipeline launch command.
  • We have removed the config argument to the ConfigMapping, @composite_solid, @solid, SolidDefinition, @executor, ExecutorDefinition, @logger, LoggerDefinition, @resource, and ResourceDefinition APIs, which we deprecated in 0.8.0. Use config_schema instead.

New

  • Python 3.8 is now fully supported.
  • -d or --working-directory can be used to specify a working directory in any command that takes in a -f or --python_file argument.
  • Removed the deprecation of create_dagster_pandas_dataframe_type. This is the currently supported API for custom pandas data frame type creation.
  • Removed gevent dependency from dagster
  • New configured API for predefining configuration for various definitions: https://legacy-docs.dagster.io/overview/configuration/#configured
  • Added hooks to enable success and failure handling policies on pipelines. This enables users to set up policies on all solids within a pipeline or on a per solid basis. Example usage can be found here
  • New instance level view of Scheduler and running schedules
  • dagster-graphql is now only required in dagit images.
