New Improved the performance of declarative automation for partitioned assets with a long materialization history. [ui] The UI now has a mobile layout for phones, with a new navigation menu and mobile versions of the Home, Jobs, Automation, Timeline, Asset Catalog, and Asset Overview pages. Pages without a mobile version show a banner with an option to always use the desktop site, which can also b…
New Loading a project whose root module is not importable now raises an error explaining that the project package is likely not installed, instead of a bare ModuleNotFoundError. [dagster-cloud] The ECS agent now supports cross-account service discovery. When the Cloud Map namespace lives in a different AWS account from the agent, the agent registers code server tasks in Cloud Map directly and reco…
New In Dagster+, alert policies can now target deployment capacity metrics — queued runs and in-progress runs — evaluated over a rolling window with aggregations such as max. In Dagster+ Serverless, fast deploys now build a Docker image instead of a Python executable when the target environment cannot run one: Serverless on Kubernetes, or a Harbor image registry. Set DAGSTER_CLOUD_DISABLE_PEX_DOCK…
New Run dequeuing is now significantly faster when concurrency pools are in use and many runs are queued, as pool state is read once per dequeue pass rather than repeatedly. In Dagster+, the MCP server's launch_job_run and launch_asset_run tools no longer require a code location and repository name. They are looked up from the job being launched. [ui] The tick timeline now supports filtering to a…
New Asset backfills whose runs have all finished but which still have partitions with no materialization status now complete as failed instead of remaining in progress indefinitely. In Dagster+, wiping and deleting dynamic partitions in a single action now also supports multi-partitioned assets that use the dynamic partitions definition as a dimension. In Dagster+, alert policies defined in a YAML…
New In Dagster+, dynamic partitions can now be wiped and deleted in a single action, clearing the asset's degraded health status. Multi-partitioned assets are not yet supported. Alert policies can now notify on successful code location deploys. [ui] Filter inputs now show your recent searches in the autocomplete dropdown before you start typing. [ui] Refreshed the Dagster and Dagster+ logos and fa…
New [ui] Added an expand/collapse all toggle to the automation condition evaluation table. Bugfixes [ui] Fixed an issue where the sensor dry run "Apply requests & commit tick result" action could launch runs even when creating or deleting dynamic partitions failed due to insufficient permissions.
New Assets whose failed partitions are all awaiting an automatic retry now report a warning health status instead of degraded. The asset health popover and alert notifications indicate that a retry is pending. [dagster-snowflake] SnowflakeDbtProjectComponent now supports configuring defs_state, so Dagster+ deployments can opt into versioned state storage. Bugfixes Fixed an issue where a config fie…
New An asset whose materialization failures are all pending an automatic retry now reports a WARNING health status instead of DEGRADED, and Slack, Microsoft Teams, and email alerts render a "Failed, retry pending" line for it. [ui] The asset graph sidebar's search now matches only assets shown in the sidebar, matches on the full asset key as well as the displayed name, lists results alphabetically…
New Declarative Automation can now automate jobs, available as a preview feature. Pass an automation_condition to define_asset_job — wrapping an asset-level condition with AutomationCondition.any_job_root_assets_match or AutomationCondition.all_job_root_assets_match — to launch a single run of the job when the condition becomes true. Evaluation history is viewable in the new Automation tab on job…
New [dagster-snowflake] Added the SnowflakeDbtProjectComponent (Preview) for natively orchestrating dbt projects on Snowflake. Documentation Added documentation for the Dagster MCP server.
Bugfixes Fixed a 401 error from the serverless I/O manager when materializing assets in an organization with more than one full deployment. Fixed a 400 error from the serverless I/O manager when materializing assets whose storage keys contain special characters.
New [ui] The asset launch dialog now automatically expands the warnings section when alerts are present. Bugfixes Fixed an issue where a fresh installation of dagster could resolve an incompatible version of grpcio-health-checking, breaking code server imports due to a protobuf version conflict. [ui] Fixed an error that occurred when viewing tick details for declarative automation runs.
New [ui] Improved the performance of the runs feed for runs that target large numbers of assets and asset checks. The feed now fetches a bounded preview of the selection and loads the full lists on demand. [dagster-aws] Added a dashboard_refresh_interval parameter to PipesEMRServerlessClient and increased its default so that Spark UI URLs are no longer invalidated prematurely during a run. (Thanks…
New [ui] The asset catalog page now renders as a single virtualized list, so workspaces with many asset groups or code locations no longer freeze the UI when expanding those sections. [dagster-dbt] Added a new "insights" option to DbtProjectComponent's include_metadata field, enabling Dagster+ Insights tracking from YAML config. [dagster-graphql] Added an optional limit argument and new assetSelec…
Bugfixes Fixed a bug where DagsterInstance.get_latest_materialization_event (and get_asset_records) could return a stale pre-wipe materialization for a wiped asset once a new run targeting the asset started or an observation was reported. In Dagster+, fixed the analogous bug where wiping partitions could leave the wiped partition's materialization as the asset's latest materialization. Fixed an is…
New Asset group names may now contain / separators to define hierarchical groups (e.g. marketing/ads). Hierarchical groups can be selected with wildcards in asset selections (e.g. group:"marketing/*") and are rendered as nested groups in the asset graph. Added an is: filter to the asset selection syntax and search filters to select assets by type (e.g. is:external, is:materializable). [dg] DG_PROJ…
New Special characters are now allowed in team owners for jobs, schedules, and sensors. (Thanks, @dragos-pop!) Added kinds tags and icons for Microsoft Fabric and OneLake. (Thanks, @MartyP233!) The BigQuery, Snowflake, and DuckDB I/O managers now skip the table write when an asset returns an empty DataFrame, logging a warning instead. This prevents incorrect type inference and degenerate tables fo…
New Added an owners parameter to build_schedule_from_partitioned_job to set owners on the resulting schedule. (Thanks, @dragos-pop!) [dagster-airlift] Added support for Python 3.12, 3.13, and 3.14. [dagster-fivetran] The Fivetran component now supports a fetch_column_metadata option to fetch column-level metadata for synced tables. [dagster-k8s] When includeConfigInLaunchedRuns.enabled is set in t…
New Schedule, sensor, and asset daemon ticks now dispatch instigators round-robin across code locations, preventing a single code location with many instigators from delaying launches in other code locations. Added dg api run launch command for launching runs from the CLI against the Dagster+ API. Improved declarative automation performance for assets sharing the same cron schedule. [ui] The asset…
New Added kinds tags for Alteryx, Boomi, and SAP. Raised the SQLite busy_timeout default from 5s to 30s on SqliteEventLogStorage and ConsolidatedSqliteEventLogStorage to better tolerate slow or network-backed $DAGSTER_HOME filesystems. [ui] Removed the "Scheduled" tab from the runs feed. [ui] The sensor tick timeline now shows more ticks on the newest page, matching the list of ticks shown in the…
New typing.Mapping and typing.Sequence annotations are now supported on op and asset inputs. Added a path_prefix parameter to DagsterGraphQLClient to support connecting to webserver deployments behind a non-root path prefix. Added a storage_kind field to TableMetadataSet to denote the storage system that backs a table (e.g., snowflake, databricks, bigquery). define_asset_job now validates owner st…
New Added an owners parameter to define_asset_job, mirroring the field on regular jobs. Improved error messages when required config is missing in Dagster jobs, with clearer guidance on which fields are missing and example config to provide. LOGS_CAPTURED event messages no longer say "Started capturing logs", since compute log managers typically upload logs on completion rather than streaming in r…
New [ui] Users can now hold Cmd or Ctrl while clicking launch, materialize, re-execute, or retry buttons to open the resulting run in a new browser tab instead of navigating away from the current page. [ui] Added an Azure DevOps kind tag icon for assets tagged with the azuredevops kind. [dg] The dg utils integrations sub-command has been removed. [dagster-databricks] DatabricksClientResource now a…
