Changelog#

1.5.9 / 0.21.9 (libraries)#

New#

  • [ui] Enabled collapsing asset groups in the global asset view when the new experimental asset graph is turned on in User Settings
  • [ui] The experimental asset graph sidebar now supports keyboard navigation via arrow keys
  • [ui] You can now right click nodes in the asset graph to materialize them or filter the graph
  • [ui] Jobs can now be searched by run ID
  • [ui] You can now launch runs from the job actions menu
  • [auto-materialize] A new AutoMaterializeRule.materialize_on_cron() rule makes it possible to create policies which materialize assets on a regular cadence.
  • [auto-materialize] If a partition-mapping-related error occurs within the Asset Daemon, a more informative error message will be provided.
  • [dagster-databricks] Extended the set of available config options to the Databricks step launcher - thanks @zyd14!

Bugfixes#

  • Fixed an issue where some schedules incorrectly skipped ticks during Daylight Savings Times transitions.
  • Returning a SensorResult from a sensor no longer overwrites a cursor if it was set via the context.
  • Fixed issue which could cause incorrect execution order when executing multi-assets with can_subset=True alongside assets which were upstream of some assets in the multi-asset, and downstream of others.
  • Previously, when creating an HourlyPartitionsDefinition with a non-UTC timezone and the default format string (or any format string not including a UTC-offset), there was no way to disambiguate between the first and second instance of the repeated hour during a daylight saving time transition. Now, for the one hour per year in which this ambiguity exists, the partition key of the second instance of the hour will have the UTC offset automatically appended to it.
  • [asset checks] Fixed a bug that caused an error when passing check_specs to AssetsDefinition.from_graph
  • [dagster-dbt] Fixed a bug in dagster-dbt that caused some dbt tests to not be selected as asset checks.
  • [dagster-dbt] Fixed an issue where multiple copies of the dbt manifest were held in memory when loading a dbt project as software-defined assets.
  • The email_on_failure sensor called deprecated methods on the context. This has been fixed

Community Contributions#

  • [dagster-deltalake] Added Delta Lake support along with support for pandas and polars. Thanks Robert Pack @roeap!
  • [dagster-graphql] Fixed the asset cursor format to use a normalized format - thanks @sisidra!
  • [dagster-databricks] Extended the set of available config options to the Databricks step launcher - thanks @zyd14!

Experimental#

  • DagsterInstance.report_runless_asset_event is now public.
  • AutoMaterializeRule.materialize_on_parent_updated now accepts an updated_parents_filter of type AutoMaterializeAssetPartitionsFilter, which allows only materializing based on updates from runs with a required set of tags.

Documentation#

Dagster Cloud#

  • Reporting runless events and manually marking an asset as successfully materialized are no possible with “Launcher” level permissions
  • [ui] Improved search and render performance of Users page, especially for large lists of users.
  • [billing] Fixed issues with correctly displaying your tax ID

1.5.8 / 0.21.8 (libraries)#

Bugfixes#

  • Fixed an error when trying to directly invoke a run status sensor when passing resources.
  • [dagster-airbyte][dagster-fivetran] Fixed an issue where EnvVars used in Airbyte or Fivetran resources would show up as their processed values in the launchpad when loading assets from a live Fivetran or Airbyte instance.

Dagster Cloud#

  • Substantially improved performance of the Dagster insights DBT/Snowflake usage job.

1.5.7 / 0.21.7 (libraries)#

New#

  • The OpExecutionContext and AssetExecutionContext now have a partition_keys property
  • [dagster-ui] The asset graph layout algorithm has been changed to a much faster one called “tight-tree”
  • [dagster-ui] The Runs table filters has a top level filter for partitions
  • [dagster-dbt] dbt-core==1.7.* is now supported.

Bugfixes#

  • Fixed an issue where some schedules skipped a tick on the day after a fall Daylight Savings Time transition.
  • Fixed a bug that caused backfill policies that execute multiple partitions in a single run not to work with dynamic partitions.
  • Fixed a bug that caused an error when build_schedule_from_partitioned_job was used with a job with multi-partitioned assets and the partitions_def argument wasn’t provided to define_asset_job.
  • We now raise an error early if the empty string is provided as an asset’s group name (Thanks Sierrra!)
  • Fixed an issue where custom setup and teardown methods were not properly called on nested Pythonic resources.
  • Added a warning message when op or asset config is passed as an argument not named config.
  • [dagster-cloud] Fixed an issue where overriding the default I/O manager could break the Snowflake-dbt insights job.
  • [auto-materialize] Fixed an issue where materializing an unpartitioned parent of a dynamic-partitioned asset would only result in the latest dynamic partition of that asset being requested. Now, all partitions will be requested.
  • [dagster-embedded-elt] Fixed an issue in dagster-embedded-elt where sling’s updated_at parameter was set to the incorrect type
  • [dagster-ui] Fixed an issue in the launchpad where selecting a partition wouldn’t correctly overwrite fields using the partition’s specific configuration

Community Contributions#

  • A docs fix to the testing concepts page, thanks @NicolaiLolansen!
  • The schema can now be overridden per asset in DB IO managers, thanks @jrstats!

Experimental#

  • Improved failure recovery and retry behavior when the daemon that launches auto-materialization runs fails or crashes in the middle of a tick.
  • [asset-checks] UI performance for displaying check results is improved
  • [asset-checks] Removed noisy experimental warning about AssetCheckKey
  • [op-concurrency] Fixed a bug where concurrency slots were not getting assigned if a run that was assigned a slot was deleted before the slot had actually been claimed during execution.
  • [dagster-pipes] The PipesSubprocessClient now inherits the environment variables of the parent process in the launched subprocess.
  • [dagster-pipes] Exceptions are now reported in the event log for framework components and from the external process.

Documentation#

1.5.6 / 0.21.6 (libraries)#

New#

  • [dagster-k8s] The PipesK8sClient will now attempt to load the appropriate kubernetes config, and exposes arguments for controlling this process.
  • [ui] The launch asset backfill modal now offers a preview dialog showing the targeted asset partitions and their backfill policies when partition mapping or varying backfill policies are present.
  • [asset-checks] New load_asset_checks_from_modules functions for loading asset checks in tandem with load_assets_from_modules.
  • Previously, the daemon process would terminate with an error if it believed that a thread might be hanging, which sometimes caused undesirable terminations when doing large backfills or auto-materializing many assets. Now, the daemon process will emit a warning instead of terminate.
  • [dagster-dbt] dagster-dbt project scaffold now uses ~/.dbt/profiles.yml if a profiles.yml is not present in the dbt project directory.
  • [dagster-dbt] @dbt_assets now support PartitionMapping using DagsterDbtTranslator.get_partition_mapping.
  • [dagster-dbt] Self dependencies can now be enabled for dbt models that are represented by @dbt_assets. To enable this, add the following metadata to your dbt model’s metadata in your dbt project:
meta:
  dagster:
    has_self_dependency: True

Bugfixes#

  • Fixed an issue where Dagster imports would throw errors when using pydantic<2.0.0 but having pydantic-core installed.
  • Previously, asset backfills that targeted partitioned assets with a LastPartitionMapping dependency would raise an error. This has been fixed.
  • Fixed a multipartitions partition mapping bug where a instance is not available to load partitions error was raised.
  • [asset-checks] Fixed an issue with conflicting op names when using build_asset_with_blocking_check
  • [ui] Viewing run logs containing very large messages no longer causes the UI to crash in Safari on macOS
  • [ui] Drilling into the graph of a graph-backed asset with 4+ inputs or outputs no longer causes the asset graph to crash with a rendering error.
  • [ui] On the backfill details page, clicking to a specific asset correctly shows the partitions that were materialized for that asset when partition mapping is in use.
  • [ui] The Asset > Partition page now loads partition details more quickly in cases where calculating the staleness of the partition took a significant amount of time.
  • Fixed a bug introduced in 1.5.0 where instances that haven’t been migrated to the latest schema hit an error upon run deletion.
  • [auto-materialize] Previously, if an asset partition was skipped on a tick for one reason, and then processed and skipped on a later tick for an additional reason, only the most recent skip reason would be tracked. Now, all skip reasons are tracked.
  • [dagster-dbt] Fixed an issue where if an exclude that didn’t match any dbt nodes was used in @dbt_assets, an error would be raised. The error is now properly handled.
  • [dagster-dbt] When invoking DbtCliResource.cli(...) in an op, AssetMaterialization's instead of Output are now emitted.

Experimental#

  • Global op concurrency slots are now released in between retries of op execution failures.

Documentation#

  • Updated the tutorial to reflect best practices and APIs as of Dagster 1.5

Dagster Cloud#

  • The report_asset_observation REST endpoint for reporting runless events is now available.

  • Dramatically improved the performance of partition-mapping, for basic hourly and daily partitions definitions
  • [ui] When viewing a list of runs, you can quickly add the tag in the “Launched by” column as a filter on the list view. Hover over the tag to see the “Add to filter” button.
  • [helm] The env vars DAGSTER_K8S_PG_PASSWORD_SECRET and DAGSTER_K8S_INSTANCE_CONFIG_MAP will no longer be set in all pods.
  • [dagster-pyspark] build_pyspark_zip now takes an exclude parameter that can be used to customize the set of excluded files.
  • [ui] Links beginning with http://, https:// in unstructured run logs (via context.log) are automatically converted to clickable links

Bugfixes#

  • Fixed an asset backfill bug where certain asset partitions with no targeted parents would hang indefinitely.
  • Fixed a bug where the source_key_prefix argument to load_assets_from_current_module and load_assets_from_package_name was ignored
  • Fixed two bugs in dagster_embedded_elt where the mode parameter was not being passed to Sling, and only one asset could be created at a time
  • Fixed a bug with handing default values for Pydantic validators on Windows
  • [ui] Clicking an asset with checks shows them in the asset graph sidebar, even if live data on the page is still loading.
  • [ui] Reported materialization events are presented more clearly in the asset graph sidebar and in other parts of the Dagster UI.
