The performance of loading the Definitions snapshot from a code server when large @multi_asset s are in use has been drastically improved.
The snowflake quickstart example project now renames the “by” column to avoid reserved snowflake names. Thanks @jcampbell!
The existing group name (if any) for an asset is now retained if the_asset.with_attributes is called without providing a group name. Previously, the existing group name was erroneously dropped. Thanks @ion-elgreco!
[dagster-dbt] Fixed an issue where Dagster events could not be streamed from dbt source freshness.
[dagster university] Removed redundant use of MetadataValue in Essentials course. Thanks @stianthaulow!
[ui] Increased the max number of plots on the asset plots page to 100.
The tag_keys argument on DagsterInstance.get_run_tagsis no longer optional. This has been done to remove an easy way of accidentally executing an extremely expensive database operation.
The maximum number of concurrent runs across all branch deployments is now configurable. This setting can now be set via GraphQL or the CLI.
[ui] In Insights, fixed display of table rows with zero change in value from the previous time period.
[ui] Added deployment-level Insights.
[ui] Fixed an issue causing void invoices to show up as “overdue” on the billing page.
[experimental] Branch deployments can now indicate the new and modified assets in the branch deployment as compared to the main deployment. To enable this feature, turn on the “Enable experimental branch deployment asset graph diffing” user setting.
[ui] When viewing logs for a run, the date for a single log row is now shown in the tooltip on the timestamp. This helps when viewing a run that takes place over more than one date.
Added suggestions to the error message when selecting asset keys that do not exist as an upstream asset or in an AssetSelection.
Improved error messages when trying to materialize a subset of a multi-asset which cannot be subset.
[dagster-snowflake] dagster-snowflake now requires snowflake-connector-python>=3.4.0
[embedded-elt] @sling_assets accepts an optional name parameter for the underlying op
[dagster-openai] dagster-openai library is now available.
[dagster-dbt] Added a new setting on DagsterDbtTranslatorSettings called enable_duplicate_source_asset_keys that allows users to set duplicate asset keys for their dbt sources. Thanks @hello-world-bfree!
Log messages in the Dagster daemon for unloadable sensors and schedules have been removed.
[ui] Search now uses a cache that persists across pageloads which should greatly improve search performance for very large orgs.
[ui] groups/code locations in the asset graph’s sidebar are now sorted alphabetically.
Fixed issue where the input/output schemas of configurable IOManagers could be ignored when providing explicit input / output run config.
Fixed an issue where enum values could not properly have a default value set in a ConfigurableResource.
Fixed an issue where graph-backed assets would sometimes lose user-provided descriptions due to a bug in internal copying.
[auto-materialize] Fixed an issue introduced in 1.6.7 where updates to ExternalAssets would be ignored when using AutoMaterializePolicies which depended on parent updates.
[asset checks] Fixed a bug with asset checks in step launchers.
[embedded-elt] Fix a bug when creating a SlingConnectionResource where a blank keyword argument would be emitted as an environment variable
[dagster-dbt] Fixed a bug where emitting events from dbt source freshness would cause an error.
[ui] Fixed a bug where using the “Terminate all runs” button with filters selected would not apply the filters to the action.
[ui] Fixed an issue where typing a search query into the search box before the search data was fetched would yield “No results” even after the data was fetched.
[asset checks] UI performance of asset checks related pages has been improved.
[dagster-dbt] The class DbtArtifacts has been added for managing the behavior of rebuilding the manifest during development but expecting a pre-built one in production.
Microsoft Teams is now supported for alerts. Documentation
A send sample alert button now exists on both the alert policies page and in the alert policies editor to make it easier to debug and configure alerts without having to wait for an event to kick them off.
Added a new run_retries.retry_on_op_or_asset_failures setting that can be set to false to make run retries only occur when there is an unexpected failure that crashes the run, allowing run-level retries to co-exist more naturally with op or asset retries. See the docs for more information.
dagster dev now sets the environment variable DAGSTER_IS_DEV_CLI allowing subprocesses to know that they were launched in a development context.
[ui] The Asset Checks page has been updated to show more information on the page itself rather than in a dialog.
[ui] Fixed an issue where the UI disallowed creating a dynamic partition if its name contained the “|” pipe character.
AssetSpec previously dropped the metadata and code_version fields, resulting in them not being attached to the corresponding asset. This has been fixed.
The new @multi_observable_source_asset decorator enables defining a set of assets that can be observed together with the same function.
[dagster-embedded-elt] New Asset Decorator @sling_assets and Resource SlingConnectionResource have been added for the [dagster-embedded-elt.sling](http://dagster-embedded-elt.sling) package. Deprecated build_sling_asset, SlingSourceConnection and SlingTargetConnection.
Added support for op-concurrency aware run dequeuing for the QueuedRunCoordinator.
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.
The dagster-airflow library as been moved to 1.x.x to denote the stability of its api's going forward.
[dagster-airflow] make_schedules_and_jobs_from_airflow_dag_bag has been added to allow for more fine grained composition of your transformed airflow DAGs into Dagster.
[dagster-airflow] Airflow dag task retries and retry_delay configuration are now converted to op RetryPolicies with all make_dagster_* apis.
[dagster-airflow] The use_airflow_template_context, mock_xcom and use_ephemeral_airflow_db params have been dropped, by default all make_dagster_* apis now use a run-scoped airflow db, similiar to how use_ephemeral_airflow_db worked.
[dagster-airflow] make_airflow_dag has been removed.
[dagster-airflow] make_airflow_dag_for_operator has been removed.
[dagster-airflow] make_airflow_dag_containerized has been removed.
[dagster-airflow] airflow_operator_to_op has been removed.
[dagster-airflow] make_dagster_repo_from_airflow_dags_path has been removed.
[dagster-airflow] make_dagster_repo_from_airflow_dag_bag has been removed.
[dagster-airflow] make_dagster_repo_from_airflow_example_dags has been removed.
[dagster-airflow] The naming convention for ops generated from airflow tasks has been changed to ${dag_id}__${task_id} from airflow_${task_id}_${unique_int}.
[dagster-airflow] The naming convention for jobs generated from airflow dags has been changed to ${dag_id} from airflow_${dag_id}.
Definitions now accepts Executor instances in its executor argument, not just ExecutorDefinitions.
@multi_asset_sensor now accepts a request_assets parameter, which allows it to directly request that assets be materialized, instead of requesting a run of a job.
Improved the performance of instantiating a Definitions when using large numbers of assets or many asset jobs.
The job passed to build_schedule_from_partitioned_job no longer needs to have a partitions_def directly assigned to it. Instead, Dagster will infer from the partitions from the assets it targets.
OpExecutionContext.asset_partition_keys_for_output no longer requires an argument to specify the default output.
The “Reload all” button on the Code Locations page in Dagit will now detect changes to a pyproject.toml file that were made while Dagit was running. Previously, Dagit needed to be restarted in order for such changes to be shown.
get_run_record_by_id has been added to DagsterInstance to provide easier access to RunRecord objects which expose the start_time and end_time of the run.
[dagit] In the “Materialize” modal, you can now choose to pass a range of asset partitions to a single run rather than launching a backfill.
[dagster-docker] Added a docker_container_op op and execute_docker_container_op helper function for running ops that launch arbitrary Docker containers. See the docs for more information.
[dagster-snowflake-pyspark] The Snowflake I/O manager now supports PySpark DataFrames.
[dagster-k8s] The Docker images include in the Dagster Helm chart are now built on the most recently released python:3.x-slim base image.
Previously, the build_asset_reconciliation_sensor could time out when evaluating ticks over large selections of assets, or assets with many partitions. A series of performance improvements should make this much less likely.
Fixed a bug that caused a failure when using run_request_for_partition in a sensor that targeted multiple jobs created via define_asset_job.
The cost of importing dagster has been reduced.
Issues preventing “re-execute from failure” from working correctly with dynamic graphs have been fixed.
[dagit] In Firefox, Dagit no longer truncates text unnecessarily in some cases.
[dagit] Dagit’s asset graph now allows you to click “Materialize” without rendering the graph if you have too many assets to display.
[dagit] Fixed a bug that stopped the backfill page from loading when assets that had previously been backfilled no longer had a PartitionsDefinition.
[dagster-k8s] Fixed an issue where k8s_job_op raised an Exception when running pods with multiple containers.
[dagster-airbyte] Loosened credentials masking for Airbyte managed ingestion, fixing the Hubspot source, thanks @joel-olazagasti!
[dagster-airbyte] When using managed ingestion, Airbyte now pulls all source types available to the instance rather than the workspace, thanks @emilija-omnisend!
[dagster-airbyte] Fixed an issue which arose when attaching freshness policies to Airbyte assets and using the multiprocessing executor.
[dagster-fivetran] Added the ability to force assets to be output for all specified Fivetran tables during a sync in the case that a sync’s API outputs are missing one or more tables.
The asset_keys and asset_selection parameters of the experimental @multi_asset_sensor decorator have been replaced with a monitored_assets parameter. This helps disambiguate them from the new request_assets parameter.
Large asset graphs can now be materialized in Dagit without needing to first enter an asset subset. Previously, if you wanted to materialize every asset in such a graph, you needed to first enter * as the asset selection before materializing the assets.
Added a pin of the sqlalchemy package to <2.0.0 due to a breaking change in that version.
Added a pin of the dbt-core package to <1.4.0 due to breaking changes in that release that affected the Dagster dbt integration. We plan to remove this pin in the next release.
Added a pin of the jupyter-client package to <8.0 due to an issue with the most recent release causing hangs while running dagstermill ops.
The nux section of dagster.yaml config has been fixed.
Changes when heartbeats occur in the daemon to avoid crashes in certain conditions.
Fixed an issue where passing a workspace file as an argument into the dagster dev command raised an error
[dagit] Fixes an issue with asset names being truncated by long asset descriptions in the asset catalog, making them impossible to click.
[dagit] The backfill page no longer fails to load if any of the asset backfills had assets that were partitioned at the time of the backfill but are no longer partitioned.
