dagster-polars has been added as an integration. Thanks @danielgafni!
[dagster-dbt] @dbt_assets now supports loading projects with semantic models.
[dagster-dbt] @dbt_assets now supports loading projects with model versions.
[dagster-dbt] get_asset_key_for_model now supports retrieving asset keys for seeds and snapshots. Thanks @aksestok!
[dagster-duckdb] The Dagster DuckDB integration supports DuckDB version 0.10.0.
[UPath I/O manager] If a non-partitioned asset is updated to have partitions, the file containing the non-partitioned asset data will be deleted when the partitioned asset is materialized, rather than raising an error.
Fixed an issue where creating a backfill of assets with dynamic partitions and a backfill policy would sometimes fail with an exception.
Fixed an issue with the type annotations on the @asset decorator causing a false positive in Pyright strict mode. Thanks @tylershunt!
[ui] On the asset graph, nodes are slightly wider allowing more text to be displayed, and group names are no longer truncated.
[ui] Fixed an issue where the groups in the asset graph would not update after an asset was switched between groups.
[dagster-k8s] Fixed an issue where setting the security_context field on the k8s_job_executor didn't correctly set the security context on the launched step pods. Thanks @krgn!
Observable source assets can now yield ObserveResults with no data_version.
You can now include FreshnessPolicys on observable source assets. These assets will be considered “Overdue” when the latest value for the “dagster/data_time” metadata value is older than what’s allowed by the freshness policy.
[ui] In Dagster Cloud, a new feature flag allows you to enable an overhauled asset overview page with a high-level stakeholder view of the asset’s health, properties, and column schema.
[kubernetes] Fixed an issue where the Kubernetes agent would sometimes leave dangling kubernetes services if the agent was interrupted during the middle of being terminated.
Within a backfill or within auto-materialize, when submitting runs for partitions of the same assets, runs are now submitted in lexicographical order of partition key, instead of in an unpredictable order.
[dagster-k8s] Include k8s pod debug info in run worker failure messages.
[dagster-dbt] Events emitted by DbtCliResource now include metadata from the dbt adapter response. This includes fields like rows_affected, query_id from the Snowflake adapter, or bytes_processed from the BigQuery adapter.
A previous change prevented asset backfills from grouping multiple assets into the same run when using BackfillPolicies under certain conditions. While the backfills would still execute in the proper order, this could lead to more individual runs than necessary. This has been fixed.
[dagster-k8s] Fixed an issue introduced in the 1.6.4 release where upgrading the Helm chart without upgrading the Dagster version used by user code caused failures in jobs using the k8s_job_executor.
[instigator-tick-logs] Fixed an issue where invoking context.log.exception in a sensor or schedule did not properly capture exception information.
[asset-checks] Fixed an issue where additional dependencies for dbt tests modeled as Dagster asset checks were not properly being deduplicated.
[dagster-dbt] Fixed an issue where dbt model, seed, or snapshot names with periods were not supported.
@observable_source_asset-decorated functions can now return an ObserveResult. This allows including metadata on the observation, in addition to a data version. This is currently only supported for non-partitioned assets.
[auto-materialize] A new AutoMaterializeRule.skip_on_not_all_parents_updated_since_cron class allows you to construct AutoMaterializePolicys which wait for all parents to be updated after the latest tick of a given cron schedule.
[Global op/asset concurrency] Ops and assets now take run priority into account when claiming global op/asset concurrency slots.
Fixed helm chart to only add flower to the K8s ingress when enabled (thanks @PenguinToast!)
Updated helm chart to use more lenient timeouts for liveness probes on user code deployments (thanks @PenguinToast!)
Bugfixes
[Helm/K8s] Due to Flower being incompatible with Celery 5.0, the Helm chart for Dagster now uses a specific image mher/flower:0.9.5 for the Flower pod.
[Dagit] Show recent runs on individual schedule pages
[Dagit] It’s no longer required to run dagster schedule up or press the Reconcile button before turning on a new schedule for the first time
[Dagit] Various improvements to the asset view. Expanded the Last Materialization Event view. Expansions to the materializations over time view, allowing for both a list view and a graphical view of materialization data.
Community Contributions
Updated many dagster-aws tests to use mocked resources instead of depending on real cloud resources, making it possible to run these tests locally. (thanks @jmsanders!)
Bugfixes
fixed an issue with retries in step launchers
[Dagit] bugfixes and improvements
Fixed an issue where dagit sometimes left hanging processes behind after exiting
Experimental
[K8s] The dagster daemon is now optionally deployed by the helm chart. This enables run-level queuing with the QueuedRunCoordinator.
Improved error handling when the intermediate storage stores and retrieves objects.
New URL scheme in Dagit, with repository details included on all paths for pipelines, solids, and schedules
Relaxed constraints for the AssetKey constructor, to enable arbitrary strings as part of the key path.
When executing a subset of a pipeline, configuration that does not apply to the current subset but would be valid in the original pipeline is now allowed and ignored.
GCSComputeLogManager was added, allowing for compute logs to be persisted to Google cloud storage
The step-partition matrix in Dagit now auto-reloads runs
Bugfixes
Dagit bugfixes and improvements
When specifying a namespace during helm install, the same namespace will now be used by the K8sScheduler or K8sRunLauncher, unless overridden.
@pipeline decorated functions with -> None typing no longer cause unexpected problems.
Fixed an issue where compute logs might not always be complete on Windows.
CliApiRunLauncher and GrpcRunLauncher have been combined into DefaultRunLauncher.
If you had one of these run launchers in your dagster.yaml, replace it with DefaultRunLauncher
or remove the run_launcher: section entirely.
New
Added a type loader for typed dictionaries: can now load typed dictionaries from config.
Bugfixes
Dagit bugfixes and improvements
Added error handling for repository errors on startup and reload
Repaired timezone offsets
Fixed pipeline explorer state for empty pipelines
Fixed Scheduler table
User-defined k8s config in the pipeline run tags (with key dagster-k8s/config) will now be
passed to the k8s jobs when using the dagster-k8s and dagster-celery-k8s run launchers.
Previously, only user-defined k8s config in the pipeline definition’s tag was passed down.
Experimental
Run queuing: the new QueuedRunCoordinator enables limiting the number of concurrent runs.
The DefaultRunCoordinator launches jobs directly from Dagit, preserving existing behavior.
