Dagster Changelog File — Dagster

Changelog

1.13.8 (core) / 0.29.8 (libraries)

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 for empty partitions.
[ui] The per-code-location "Docs" tab is now "Components", with its content available under a "Library" subtab. Existing /docs links continue to work via redirect.
[dagster-aws] The EMR PySpark step launcher now honors a configured S3 job package path.
[dagster-cloud] code_server.* metrics now carry a server_instance_id tag identifying the underlying gRPC server process. For multi-replica code locations, the tag identifies whichever replica answered the most recent metrics ping.

Bugfixes

InstigationLogger now stringifies log record attributes that are not JSON-serializable instead of failing to emit the log. (Thanks, @jonaslb!)
Fixed a SQL injection vulnerability in dagster-clickhouse, dagster-clickhouse-pandas, and dagster-clickhouse-polars when using dynamic partition keys. ClickHouse partition queries now bind partition key values as driver parameters instead of interpolating them into SQL strings.
Fixed an issue where tag values in component YAML files were not coerced correctly.
[dg] dg labs ai dispatch no longer writes a plan.md artifact into version control.
[dg] Fixed an error that occurred when using TypedDict-typed fields in component configuration.
[ui] Fixed partition step status labels and squares that rendered incorrectly after the CSS Modules migration.
[ui] Fixed backfill progress not reaching 100% until all runs had completed.
[dagster-databricks] Fixed Databricks workspace job list pagination and added retries for rate-limit responses.
[dagster-dbt] Fixed DbtProject.prepare() to always run dbt deps when dependency files are present.
[dagster-dbt] Fixed YAML-based translation in DbtProjectComponent subclasses to also translate dependency keys.
[dagster-dbt] Fixed an issue where dbt unit tests could be ignored unexpectedly.
[dagster-dbt] Fixed incorrect asset key translation when generating column lineage with DbtProjectComponent.
[dagster-dbt] Fixed unbounded recursive copying of the .local_defs_state() directory when a dbt project was located at the repository root.
[dagster-cloud-cli] Fixed dg plus deploy failing with No module named pip in uv-managed environments.
[dagster-cloud-cli] Removed an overly strict dependency-file check from the Docker deploy path.

Documentation

Added an integration reference for dagster-elasticsearch.
Added documentation for the OpenLineage integration.
Added documentation for dagster-hf-datasets.
Added an example covering deployment strategies.

1.13.7 (core) / 0.29.7 (libraries)

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 the Helm chart, run pods now inherit nodeSelector, tolerations, and podSecurityContext from user deployment configuration.

Bugfixes

Fixed a SQL injection vulnerability in dagster-clickhouse, dagster-clickhouse-pandas, and dagster-clickhouse-polars when using dynamic partition keys. ClickHouse partition queries now use driver parameter binding instead of interpolating partition key values into SQL strings.
Fixed a race condition where readers polling for a run to reach FAILURE could observe the failed status before the dagster/failure_reason tag was written.
Fixed a regression where a blocking asset check that did not emit a result (e.g. a dbt test that dbt declined to run under indirect_selection: cautious or buildable) could silently cause downstream assets to be skipped. Missing blocking check results now allow downstream assets to proceed and log a warning; failed blocking checks continue to fail the step and the run as before.
Improved deduplication in AutomationCondition.any_downstream_conditions() to prevent recursive blowups in condition size when combined with other automation conditions.
[ui] Fixed extra scrollbars appearing in the asset overview and asset sidebar.
[dagster-k8s] Fixed an AttributeError when using kubernetes client v36+, which uses PEP 585 dict syntax (e.g. dict[str, str]) in its OpenAPI type annotations. (Thanks, @vanika02!)

1.13.6 (core) / 0.29.6 (libraries)

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 catalog now shows a toggle to hide duplicate connections-defined assets when an SDA and a connection target the same table, and the asset sidebar links to matched assets.
[dagster-dbt] Added a configurable job pool to DbtCloudComponent and DbtCloudWorkspace to work around dbt Cloud's one-concurrent-run-per-job limit.

Bugfixes

Fixed an issue where asset keys and partitions containing leading "/" characters or ".." characters would sometimes cause IOManagers to read and write outside of the supplied base_path.
Fixed a regression where a blocking asset check that did not emit a result (e.g. a dbt test skipped under indirect_selection: cautious or buildable) would silently cause downstream assets to be skipped. Missing check results now allow downstream assets to proceed; failed checks still fail the step.
Softened the job_snapshot_id mismatch invariant in execution plan persistence from a crash to a warning, preventing run launch failures when client and server compute slightly different snapshot IDs.
Pinned antlr4-python3-runtime to <4.14 to prevent potential breakage from future ANTLR minor version bumps.
[ui] Fixed minor flex alignment issues for tags and metadata buttons on asset catalog detail pages.
[dagster-k8s] Added support for the PEP 585 dict[str, str] syntax used by the kubernetes client v36+ when snake-casing model dictionaries, fixing an AttributeError: module 'kubernetes.client.models' has no attribute 'dict[str, str]' raised on kubernetes>=36. (Thanks, @vanika02!)

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 table below.
[dagster-k8s] Added a delete_pod_on_completion flag to PipesK8sClient.run, allowing callers to opt out of the automatic pod deletion at the end of a Pipes run.
[dagstermill] Dropped support for papermill 1.x. dagstermill now requires papermill>=2.0.0.

Bugfixes

Job backfills now retry on transient daemon errors such as code-server unreachable, matching the existing behavior for asset backfills. The DAGSTER_MAX_ASSET_BACKFILL_RETRIES environment variable has been renamed to DAGSTER_MAX_BACKFILL_RETRIES, with a fallback to the old name for backwards compatibility.
Fixed a bug where asset checks could be dropped from a JobDefinition when selected as part of a subset selection.
Fixed a bug where, in a partitioned-asset backfill running multiple partitions concurrently, an inline AssetCheckResult could record a target_materialization pointing to a different partition's materialization.
Fixed a regression introduced in 1.12.10 where OutputContext.asset_partition_key_range and InputContext.asset_partition_key_range could raise CheckError: The instance is not available to load partitions for assets using a MultiPartitionsDefinition that includes a DynamicPartitionsDefinition.
Improved the error message shown when the instance is not available to load dynamic partitions, recommending the use of partition_loading_context.
[ui] Fixed an issue where viewing the Lineage tab for an asset could cause the page header to disappear.
[dagster-dbt] Fixed a bug where, when a dbt asset selection grew large enough to switch from inline --select/--exclude to a temporary selectors.yml, runtime --exclude arguments were silently dropped.
[dagster-dbt] Fixed runtime selection arguments not being properly applied when used with @dbt_assets ops.
[dagstermill] Increased the default Jupyter kernel-startup timeout for dagstermill notebook ops from 60s to 120s.

1.13.4 (core) / 0.29.4 (libraries)

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 strings at definition time, producing clearer error messages for invalid owners.
[ui] The schedule: and sensor: selector syntax now matches assets in jobs targeted by the schedule or sensor, in addition to assets directly in the asset selection.
[dagster-azure] Added a configurable endpoint_suffix parameter to ADLS2 and Blob Storage utilities, resources, components, and compute log manager (also exposed as endpointSuffix in the Helm chart for AzureBlobComputeLogManager), enabling Azure Government Cloud, Azure China, and other sovereign cloud endpoints.
[dagster-dbt] Added a translation parameter to DbtCloudComponent for customizing how dbt models are translated into Dagster assets.
[dagster-soda] Added a new dagster-soda library (preview) containing the SodaScanComponent for executing Soda Core data quality checks.

[dagster-airbyte] Fixed an issue where Airbyte job timestamp parsing could fail with newer Airbyte API versions due to stricter ISO format handling.
[dagster-aws] InsufficientFreeAddressesInSubnet and "Task provisioning failed" are now treated as transient ECS stop reasons, so affected runs are retried instead of marked as a permanent failure.
[dagster-dbt] Fixed a bug where path-based dbt selectors did not match assets correctly because absolute paths were not calculated relative to the project root.
[dagster-dbt] Fixed an issue where conflicting source metadata could spuriously raise an error.

Documentation

Added documentation for multi-region failover in Dagster+.
Renamed the DuckDB integration documentation to MotherDuck.
Rebranded the in-app Compass assistant as Dagster+ AI in documentation.

1.13.3 (core) / 0.29.3 (libraries)

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 real time.
[ui] Added client-side validation for the deployment settings YAML editor that warns when unknown keys are detected.
[ui] Op tags are now shown on the asset details page in a separate "Op tags" row, alongside the asset's own tags.
[ui] Redesigned the sensor dry run dialog with a stacked cursor layout, copy buttons for cursor values, and an inline run config preview.
[dagster-clickhouse] Added new dagster-clickhouse, dagster-clickhouse-pandas, and dagster-clickhouse-polars libraries with native ClickHouse resources, IO managers, and dg components.
[dagster-cloud] The EcsUserCodeLauncher now accepts a repository_credentials config option, allowing ECR credentials to be configured at the agent or deployment level instead of only per code location.
[dagster-postgres] Added workload identity federation (WIF) authentication for PostgreSQL via a new auth_provider config option (azure_wif, gcp_wif, or aws_wif), with optional extras dagster-postgres[azure], dagster-postgres[gcp], and dagster-postgres[aws].

1.13.0 (core) / 0.29.0 (libraries)

Major Changes Since 1.12.0

AI-assisted development: Released dagster-io/skills, a collection of Dagster-focused AI skills for coding agents like Claude Code, OpenAI Codex, and others. Expanded dg api commands for programmatic inspection of assets, runs, jobs, schedules, and more.
Partitioned asset checks: Asset checks can now target specific partitions of an upstream asset, aligning data quality logic with how partitioned data is produced and monitored.
State-backed components enabled by default: Integrations that depend on external metadata (dbt, Fivetran, Airbyte, Tableau, Looker, etc.) now use persisted local state by default, providing a more predictable code location loading experience.
Virtual assets (preview): New is_virtual parameter on @asset and AssetSpec for modeling assets like database views that automatically reflect upstream changes without explicit materialization.
20+ new components: Added or expanded components for dbt Cloud, Spark, Azure (Blob Storage, ADLS2), GCP (BigQuery, GCS, Dataproc), Databricks, Tableau, Looker, Census, Polytomic, and more. Integrations gained richer observability, metadata, and operational support.
Deeper integration support: dbt Cloud supports partitioned assets; Databricks gained job-level subsetting and auto-cancel on run termination; Fivetran added polling sensors, retry-on-reschedule, and resync support; BI integrations auto-enrich assets with table metadata for cross-system lineage.
Dagster+ improvements: Organization-level timezone settings, service users for Pro accounts, more resilient code server redeploy behavior, improved agent failure recovery, and expanded insights and alerting workflows.

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 for empty partitions.
[ui] The per-code-location "Docs" tab is now "Components", with its content available under a "Library" subtab. Existing /docs links continue to work via redirect.
[dagster-aws] The EMR PySpark step launcher now honors a configured S3 job package path.
[dagster-cloud] code_server.* metrics now carry a server_instance_id tag identifying the underlying gRPC server process. For multi-replica code locations, the tag identifies whichever replica answered the most recent metrics ping.

Bugfixes

Bugfixes

Fixed a SQL injection vulnerability in dagster-clickhouse, dagster-clickhouse-pandas, and dagster-clickhouse-polars when using dynamic partition keys. ClickHouse partition queries now use driver parameter binding instead of interpolating partition key values into SQL strings.
Fixed a race condition where readers polling for a run to reach FAILURE could observe the failed status before the dagster/failure_reason tag was written.
Fixed a regression where a blocking asset check that did not emit a result (e.g. a dbt test that dbt declined to run under indirect_selection: cautious or buildable) could silently cause downstream assets to be skipped. Missing blocking check results now allow downstream assets to proceed and log a warning; failed blocking checks continue to fail the step and the run as before.
Improved deduplication in AutomationCondition.any_downstream_conditions() to prevent recursive blowups in condition size when combined with other automation conditions.
[ui] Fixed extra scrollbars appearing in the asset overview and asset sidebar.
[dagster-k8s] Fixed an AttributeError when using kubernetes client v36+, which uses PEP 585 dict syntax (e.g. dict[str, str]) in its OpenAPI type annotations. (Thanks, @vanika02!)

1.13.6 (core) / 0.29.6 (libraries)

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 catalog now shows a toggle to hide duplicate connections-defined assets when an SDA and a connection target the same table, and the asset sidebar links to matched assets.
[dagster-dbt] Added a configurable job pool to DbtCloudComponent and DbtCloudWorkspace to work around dbt Cloud's one-concurrent-run-per-job limit.

Bugfixes

Fixed an issue where asset keys and partitions containing leading "/" characters or ".." characters would sometimes cause IOManagers to read and write outside of the supplied base_path.
Fixed a regression where a blocking asset check that did not emit a result (e.g. a dbt test skipped under indirect_selection: cautious or buildable) would silently cause downstream assets to be skipped. Missing check results now allow downstream assets to proceed; failed checks still fail the step.
Softened the job_snapshot_id mismatch invariant in execution plan persistence from a crash to a warning, preventing run launch failures when client and server compute slightly different snapshot IDs.
Pinned antlr4-python3-runtime to <4.14 to prevent potential breakage from future ANTLR minor version bumps.
[ui] Fixed minor flex alignment issues for tags and metadata buttons on asset catalog detail pages.
[dagster-k8s] Added support for the PEP 585 dict[str, str] syntax used by the kubernetes client v36+ when snake-casing model dictionaries, fixing an AttributeError: module 'kubernetes.client.models' has no attribute 'dict[str, str]' raised on kubernetes>=36. (Thanks, @vanika02!)

[ui] The sensor tick timeline now shows more ticks on the newest page, matching the list of ticks shown in the table below.
[dagster-k8s] Added a delete_pod_on_completion flag to PipesK8sClient.run, allowing callers to opt out of the automatic pod deletion at the end of a Pipes run.
[dagstermill] Dropped support for papermill 1.x. dagstermill now requires papermill>=2.0.0.

Bugfixes

Job backfills now retry on transient daemon errors such as code-server unreachable, matching the existing behavior for asset backfills. The DAGSTER_MAX_ASSET_BACKFILL_RETRIES environment variable has been renamed to DAGSTER_MAX_BACKFILL_RETRIES, with a fallback to the old name for backwards compatibility.
Fixed a bug where asset checks could be dropped from a JobDefinition when selected as part of a subset selection.
Fixed a bug where, in a partitioned-asset backfill running multiple partitions concurrently, an inline AssetCheckResult could record a target_materialization pointing to a different partition's materialization.
Fixed a regression introduced in 1.12.10 where OutputContext.asset_partition_key_range and InputContext.asset_partition_key_range could raise CheckError: The instance is not available to load partitions for assets using a MultiPartitionsDefinition that includes a DynamicPartitionsDefinition.
Improved the error message shown when the instance is not available to load dynamic partitions, recommending the use of partition_loading_context.
[ui] Fixed an issue where viewing the Lineage tab for an asset could cause the page header to disappear.
[dagster-dbt] Fixed a bug where, when a dbt asset selection grew large enough to switch from inline --select/--exclude to a temporary selectors.yml, runtime --exclude arguments were silently dropped.
[dagster-dbt] Fixed runtime selection arguments not being properly applied when used with @dbt_assets ops.
[dagstermill] Increased the default Jupyter kernel-startup timeout for dagstermill notebook ops from 60s to 120s.

define_asset_job now validates owner strings at definition time, producing clearer error messages for invalid owners.
[ui] The schedule: and sensor: selector syntax now matches assets in jobs targeted by the schedule or sensor, in addition to assets directly in the asset selection.
[dagster-azure] Added a configurable endpoint_suffix parameter to ADLS2 and Blob Storage utilities, resources, components, and compute log manager (also exposed as endpointSuffix in the Helm chart for AzureBlobComputeLogManager), enabling Azure Government Cloud, Azure China, and other sovereign cloud endpoints.

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 real time.
[ui] Added client-side validation for the deployment settings YAML editor that warns when unknown keys are detected.
[ui] Op tags are now shown on the asset details page in a separate "Op tags" row, alongside the asset's own tags.
[ui] Redesigned the sensor dry run dialog with a stacked cursor layout, copy buttons for cursor values, and an inline run config preview.

Major Changes Since 1.12.0

AI-assisted development: Released dagster-io/skills, a collection of Dagster-focused AI skills for coding agents like Claude Code, OpenAI Codex, and others. Expanded dg api commands for programmatic inspection of assets, runs, jobs, schedules, and more.
Partitioned asset checks: Asset checks can now target specific partitions of an upstream asset, aligning data quality logic with how partitioned data is produced and monitored.
State-backed components enabled by default: Integrations that depend on external metadata (dbt, Fivetran, Airbyte, Tableau, Looker, etc.) now use persisted local state by default, providing a more predictable code location loading experience.
Virtual assets (preview): New is_virtual parameter on @asset and AssetSpec for modeling assets like database views that automatically reflect upstream changes without explicit materialization.
20+ new components: Added or expanded components for dbt Cloud, Spark, Azure (Blob Storage, ADLS2), GCP (BigQuery, GCS, Dataproc), Databricks, Tableau, Looker, Census, Polytomic, and more. Integrations gained richer observability, metadata, and operational support.
Deeper integration support: dbt Cloud supports partitioned assets; Databricks gained job-level subsetting and auto-cancel on run termination; Fivetran added polling sensors, retry-on-reschedule, and resync support; BI integrations auto-enrich assets with table metadata for cross-system lineage.
Dagster+ improvements: Organization-level timezone settings, service users for Pro accounts, more resilient code server redeploy behavior, improved agent failure recovery, and expanded insights and alerting workflows.

[dagster-aws] Fixed an issue in PipesEMRServerlessClient where a custom CloudWatch log group name configured in monitoringConfiguration.cloudWatchLoggingConfiguration.logGroupName was ignored, causing log streaming to always use the default /aws/emr-serverless log group. (Thanks, @kchainani-figma!)
[ui] Fixed the asset recent updates trend visualization when multiple event types share the same run ID.
[ui] Fixed text wrapping and spacing in the asset event detail view for long partition names and run titles.
