The AutomationCondition.eager(), AutomationCondition.missing(), and AutomationCondition.on_cron conditions are now compatible with asset checks.
Added AssetSelection.materializable(), which returns only assets that are materializable in an existing selection.
Added a new AutomationCondition.all_deps_blocking_checks_passed condition, which can be used to prevent materialization when any upstream blocking checks have failed.
Added a code_version parameter to the @graph_asset decorator.
If a LaunchPartitionBackfill mutation is submitted to GQL with invalid partition keys, it will now return an early PartitionKeysNotFoundError.
AssetSelection.checks_for_assets now accepts AssetKeys and string asset keys, in addition to AssetsDefinitions.

[dagster-aws] New AWS EMR Dagster Pipes client (dagster_aws.pipes.PipesEMRCLient ) for running and monitoring AWS EMR jobs from Dagster.
Fixed an issue which could cause incorrect evaluation results when using self-dependent partition mappings with AutomationConditions that operate over dependencies.
[ui] Fixed an issue where the breadcumb on asset pages would flicker nonstop.
[dagster-embedded-elt] Fixed extraction of metadata for dlt assets whose source and destination identifiers differ.
[dagster-databricks] Fixed a permissioning gap that existed with the DatabricksPySparkStepLauncher, so that permissions are now set correctly for non-admin users.
[dagster-dbt] Fixed an issue where column metadata generated with fetch_column_metadata did not work properly for models imported through dbt dependencies.
[experimental] AutomationCondition.eager() will now only launch runs for missing partitions which become missing after the condition has been added to the asset. This avoids situations in which the eager policy kicks off a large amount of work when added to an asset with many missing historical static/dynamic partitions.
[experimental] Added a new AutomationCondition.asset_matches() condition, which can apply a condition against an arbitrary asset in the graph.
[experimental] Added the ability to specify multiple kinds for an asset with the kinds parameter.
[dagster-github] Added create_pull_request method on GithubClient that enables creating a pull request.
[dagster-github] Added create_ref method on GithubClient that enables creating a new branch.
[dagster-embedded-elt] dlt assets now generate column metadata for child tables.
[dagster-embedded-elt] dlt assets can now fetch row count metadata with dlt.run(...).fetch_row_count() for both partitioned and non-partitioned assets. Thanks @kristianandre!
[dagster-airbyte] relation identifier metadata is now attached to Airbyte assets.
[dagster-embedded-elt] relation identifier metadata is now attached to sling assets.
[dagster-embedded-elt] relation identifier metadata is now attached to dlt assets.
JobDefinition, @job, and define_asset_job now take a run_tags parameter. If run_tags are defined, they will be attached to all runs of the job, and tags will not be. If run_tags is not set, then tags are attached to all runs of the job (status quo behavior). This change enables the separation of definition-level and run-level tags on jobs.
Then env var DAGSTER_COMPUTE_LOG_TAIL_WAIT_AFTER_FINISH can now be used to pause before capturing logs (thanks @HynekBlaha!)
The kinds parameter is now available on AssetSpec.
OutputContext now exposes the AssetSpec of the asset that is being stored as an output (thanks, @marijncv!)
[experimental] Backfills are incorporated into the Runs page to improve observability and provide a more simplified UI. See the GitHub discussion for more details.
[ui] The updated navigation is now enabled for all users. You can revert to the legacy navigation via a feature flag. See GitHub discussion for more.
[ui] Improved performance for loading partition statuses of an asset job.
[dagster-docker] Run containers launched by the DockerRunLauncher now include dagster/job_name and dagster/run_id labels.
[dagster-aws] The ECS launcher now automatically retries transient ECS RunTask failures (like capacity placement failures).
Changed the log volume for global concurrency blocked runs in the run coordinator to be less spammy.
[ui] Asset checks are now visible in the run page header when launched from a schedule.
[ui] Fixed asset group outlines not rendering properly in Safari.
[ui] Reporting a materialization event now removes the asset from the asset health "Execution failures" list and returns the asset to a green / success state.
[ui] When setting an AutomationCondition on an asset, the label of this condition will now be shown in the sidebar on the Asset Details page.
[ui] Previously, filtering runs by Created date would include runs that had been updated after the lower bound of the requested time range. This has been updated so that only runs created after the lower bound will be included.
[ui] When using the new experimental navigation flag, added a fix for the automations page for code locations that have schedules but no sensors.
[ui] Fixed tag wrapping on asset column schema table.
[ui] Restored object counts on the code location list view.
[ui] Padding when displaying warnings on unsupported run coordinators has been corrected (thanks @hainenber!)
[dagster-k8s] Fixed an issue where run termination sometimes did not terminate all step processes when using the k8s_job_executor, if the termination was initiated while it was in the middle of launching a step pod.
AssetSpec now has a with_io_manager_key method that returns an AssetSpec with the appropriate metadata entry to dictate the key for the IO manager used to load it. The deprecation warning for SourceAsset now references this method.
Added a max_runtime_seconds configuration option to run monitoring, allowing you to specify that any run in your Dagster deployment should terminate if it exceeds a certain runtime. Prevoiusly, jobs had to be individually tagged with a dagster/max_runtime tag in order to take advantage of this feature. Jobs and runs can still be tagged in order to override this value for an individual run.
It is now possible to set both tags and a custom execution_fn on a ScheduleDefinition. Schedule tags are intended to annotate the definition and can be used to search and filter in the UI. They will not be attached to run requests emitted from the schedule if a custom execution_fn is provided. If no custom execution_fn is provided, then for back-compatibility the tags will also be automatically attached to run requests emitted from the schedule.
SensorDefinition and all of its variants/decorators now accept a tags parameter. The tags annotate the definition and can be used to search and filter in the UI.
Added the dagster definitions validate command to Dagster CLI. This command validates if Dagster definitions are loadable.
[dagster-databricks] Databricks Pipes now allow running tasks in existing clusters.
Fixed an issue where calling build_op_context in a unit test would sometimes raise a TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object Exception on process shutdown.
[dagster-webserver] Fix an issue where the incorrect sensor/schedule state would appear when using DefaultScheduleStatus.STOPPED / DefaultSensorStatus.STOPPED after performing a reset.
Fixed an issue where users with Launcher permissions for a particular code location were not able to cancel backfills targeting only assets in that code location.
Fixed an issue preventing long-running alerts from being sent when there was a quick subsequent run.
Added --partition-range option to dagster asset materialize CLI. This option only works for assets with single-run Backfill Policies.
Added a new .without() method to AutomationCondition.eager(), AutomationCondition.on_cron(), and AutomationCondition.on_missing() which allows sub-conditions to be removed, e.g. AutomationCondition.eager().without(AutomationCondition.in_latest_time_window()).
Added AutomationCondition.on_missing(), which materializes an asset partition as soon as all of its parent partitions are filled in.
pyproject.toml can now load multiple Python modules as individual Code Locations. Thanks, @bdart!
[ui] If a code location has errors, a button will be shown to view the error on any page in the UI.
[dagster-adls2] The ADLS2PickleIOManager now accepts lease_duration configuration. Thanks, @0xfabioo!
[dagster-embedded-elt] Added an option to fetch row count metadata after running a Sling sync by calling sling.replicate(...).fetch_row_count().
[dagster-fivetran] The dagster-fivetran integration will now automatically pull and attach column schema metadata after each sync.
Fixed an issue which could cause errors when using AutomationCondition.any_downstream_condition() with downstream AutoMaterializePolicy objects.
Fixed an issue where process_config_and_initialize did not properly handle processing nested resource config.
[ui] Fixed an issue that would cause some AutomationCondition evaluations to be labeled DepConditionWrapperCondition instead of the key that they were evaluated against.
[dagster-webserver] Fixed an issue with code locations appearing in fluctuating incorrect state in deployments with multiple webserver processes.
[dagster-embedded-elt] Fixed an issue where Sling column lineage did not correctly resolve int the Dagster UI.
[dagster-k8s] The wait_for_pod check now waits until all pods are available, rather than erroneously returning after the first pod becomes available. Thanks @easontm!
The AssetSpec constructor now raises an error if an invalid group name is provided, instead of an error being raised when constructing the Definitions object.
dagster/relation_identifier metadata is now automatically attached to assets which are stored using a DbIOManager.
[ui] Streamlined the code location list view.
[ui] The “group by” selection on the Timeline Overview page is now part of the query parameters, meaning it will be retained when linked to directly or when navigating between pages.
[dagster-dbt] When instantiating DbtCliResource, the project_dir argument will now override the DBT_PROJECT_DIR environment variable if it exists in the local environment (thanks, @marijncv!).
[dagster-embedded-elt] dlt assets now generate rows_loaded metadata (thanks, @kristianandre!).
Fixed a bug where setting asset_selection=[] on RunRequest objects yielded from sensors using asset_selection would select all assets instead of none.
Fixed bug where the tick status filter for batch-fetched graphql sensors was not being respected.
[examples] Fixed missing assets in assets_dbt_python example.
[dagster-airbyte] Updated the op names generated for Airbyte assets to include the full connection ID, avoiding name collisions.
[dagster-dbt] Fixed issue causing dagster-dbt to be unable to load dbt projects where the adapter did not have a database field set (thanks, @dargmuesli!)
[dagster-dbt] Removed a warning about not being able to load the dbt.adapters.duckdb module when loading dbt assets without that package installed.
You may now wipe specific asset partitions directly from the execution context in user code by calling DagsterInstance.wipe_asset_partitions.
Dagster+ users with a "Viewer" role can now create private catalog views.
Fixed an issue where the default IOManager used by Dagster+ Serverless did not respect setting allow_missing_partitions as metadata on a downstream asset.
Fixed an issue where runs in Dagster+ Serverless that materialized partitioned assets would sometimes fail with an object has no attribute '_base_path' error.
[dagster-graphql] Fixed an issue where the statuses filter argument to the sensorsOrError GraphQL field was sometimes ignored when querying GraphQL for multiple sensors at the same time.
Updated multi-asset sensor definition to be less likely to timeout queries against the asset history storage.
Consolidated the CapturedLogManager and ComputeLogManager APIs into a single base class.
[ui] Added an option under user settings to clear client side indexeddb caches as an escape hatch for caching related bugs.
[dagster-aws, dagster-pipes] Added a new PipesECSClient to allow Dagster to interface with ECS tasks.
[dagster-dbt] Increased the default timeout when terminating a run that is running a dbt subprocess to wait 25 seconds for the subprocess to cleanly terminate. Previously, it would only wait 2 seconds.
[dagster-sdf] Increased the default timeout when terminating a run that is running an sdf subprocess to wait 25 seconds for the subprocess to cleanly terminate. Previously, it would only wait 2 seconds.
[dagster-sdf] Added support for caching and asset selection (Thanks, akbog!)
[dagster-dlt] Added support for AutomationCondition using DagsterDltTranslator.get_automation_condition() (Thanks, aksestok!)
[ui] Fixed a bug where in-progress runs from a backfill could not be terminated from the backfill UI.
[ui] Fixed a bug that caused an "Asset must be part of at least one job" error when clicking on an external asset in the asset graph UI
Fixed an issue where viewing run logs with the latest 5.0 release of the watchdog package raised an exception.
[ui] Fixed issue causing the “filter to group” action in the lineage graph to have no effect.
[ui] Fixed case sensitivity when searching for partitions in the launchpad.
[ui] Fixed a bug which would redirect to the events tab for an asset if you loaded the partitions tab directly.
[ui] Fixed issue causing runs to get skipped when paging through the runs list (Thanks, @HynekBlaha!)
[ui] Fixed a bug where the asset catalog list view for a particular group would show all assets.
[dagster-dbt] fix bug where empty newlines in raw dbt logs were not being handled correctly.
[dagster-k8s, dagster-celery-k8s] Correctly set dagster/image label when image is provided from user_defined_k8s_config. (Thanks, @HynekBlaha!)
[dagster-duckdb] Fixed an issue for DuckDB versions older than 1.0.0 where an unsupported configuration option, custom_user_agent, was provided by default
[dagster-k8s] Fixed an issue where Kubernetes Pipes failed to create a pod if the op name contained capital or non-alphanumeric containers.
[dagster-embedded-elt] Fixed an issue where dbt assets downstream of Sling were skipped
[dagser-aws]: Direct AWS API arguments in PipesGlueClient.run have been deprecated and will be removed in 1.9.0. The new params argument should be used instead.
The default io_manager on Serverless now supports the allow_missing_partitions configuration option.
Fixed a bug that caused an error when loading the launchpad for a partition, when using in Dagster+ with an agent with version below 1.8.2
1.8.3 (core) / 0.24.3 (libraries) (YANKED - This version of Dagster resulted in errors when trying to launch runs that target individual asset partitions)#
When different assets within a code location have different PartitionsDefinitions, there will no longer be an implicit asset job __ASSET_JOB_... for each PartitionsDefinition; there will just be one with all the assets. This reduces the time it takes to load code locations with assets with many different PartitionsDefinitions.
[ui] Fixed a collection of broken links pointing to renamed Declarative Automation pages.
[dagster-dbt] Fixed issue preventing usage of MultiPartitionMapping with @dbt_assets (Thanks, @arookieds!)
[dagster-azure] Fixed issue that would cause an error when configuring an AzureBlobComputeLogManager without a secret_key (Thanks, @ion-elgreco and @HynekBlaha!)
Previously, it was possible to set max_materializations_per_minute on an AutoMaterializePolicy to a non-positive number. This will now result in an error.
[dagster-dbt] When invokingdagster-dbt project scaffold on a dbt project directory, if a profiles.yml exists in the root of the directory, its contents are used to add dbt adapter packages to the scaffolded setup.py.
The default sentinel value for the multiprocessing executor’s max_concurrent field has been changed from 0 to None to more clearly signal its intent. A value of 0 is still interpreted as the sentinel value which dynamically allocates max_concurrent based on detected CPU count.
The experimental agent config setting agent_replicashas been deprecated in favor of a new name isolated_agents (agentReplicas --> isolatedAgents in the helm chart). Upgrading to the new name requires all code locations to be on 1.4.3 or greater.
Auto-materialize history – We’ve added a UI that tracks why assets were or were not materialized according to theirAutoMaterializePolicy. It’s located under Assets → Select an asset with an AutoMaterializePolicy → Auto-materialize history tab.
Auto-materialize performance – We’ve made significant performance improvements to the Asset Daemon, allowing it to keep up with asset graphs containing thousands of assets and assets with a large history of previously-materialized partitions.
Asset backfill cancellation — Asset backfills can now be canceled, bring them to parity with job backfills. When an asset backfill is requested for cancellation, the daemon cancels runs until all runs are terminated, then marks the backfill as “canceled”.
non_argument_deps → deps – We’ve deprecated the non_argument_deps parameter of @asset and @multi_asset in favor of a new deps parameter. The new parameter makes it clear that this is a first-class way of defining dependencies, makes code more concise, and accepts AssetsDefinition and SourceAsset objects, in addition to the strs and AssetKeys that the previous parameter accepted.
Group-level asset status UI – the new Assets Overview dashboard, located underneath the Activity tab of the Overview page, shows the status all the assets in your deployment, rolled up by group.
Op concurrency (experimental) — We’ve added a feature that allows limiting the number of concurrently executing ops across runs. [docs]
DynamicPartitionsDefinition and SensorResult are no longer marked experimental.
Automatically observe source assets, without defining jobs (experimental – The @observable_source_asset decorator now accepts an auto_observe_interval_minutes parameter. If the asset daemon is turned on, then the observation function will automatically be run at this interval. Downstream assets with eager auto-materialize policies will automatically run if the observation function indicates that the source asset has changed. [docs]
Dagit → Dagster UI – To reduce the number of Dagster-specific terms that new users need to learn when learning Dagster, “Dagit” has been renamed to the “The Dagster UI”. The dagit package is deprecated in favor of the dagster-webserver package.
Default config in the Launchpad - When you open the launchpad to kick off a job or asset materialization, Dagster will now automatically populate the default values for each field.
The new @dbt_assets decorator allows much more control over how Dagster runs your dbt project. [docs]
The new dagster-dbt project scaffold command line interface makes it easy to create files and directories for a Dagster project that wraps an existing dbt project.
Improved APIs for defining asset dependencies – The new get_asset_key_for_model and get_asset_key_for_source utilities make it easy to specify dependencies between upstream dbt assets and downstream non-dbt assets. And you can now more easily specify dependencies between dbt models and upstream non-dbt assets by specifying Dagster asset keys in the dbt metadata for dbt sources.
The published Dagster Docker images now use Python 3.10, instead of 3.7.
We’ve deprecated the non_argument_deps parameter of @asset and @multi_asset in favor of a new deps parameter. The new parameter makes it clear that this is a first-class way of defining dependencies, makes code more concise, and accepts AssetsDefinition and SourceAsset objects, in addition to the strs and AssetKeys that the previous parameter accepted.
The UPathIOManager can now be extended to load multiple partitions asynchronously (Thanks Daniel Gafni!).
By default, Dagster will now automatically load default config values into the launchpad. This behavior can be disabled in the user settings page.
[dagster-k8s] The Helm chart now sets readiness probes on user code deployment servers by default. These can be disabled with dagster-user-deployments.deployments.[...].readinessProbe.enabled=false.
[dagster-airbyte] In line with the deprecation of non_argument_deps in favor of deps, build_airbyte_assets now accepts a deps parameter.
[dagstermill] In line with the deprecation of non_argument_deps in favor of deps, define_dagstermill_asset now accepts a deps parameter.
[dagster-dbt] A new CLI utility dagster-dbt project scaffold has been provided to scaffold a Dagster code location for an existing dbt project.
Duplicate partition keys passed to StaticPartitionsDefinition will now raise an error.
Fixed a bug that caused lazy AutoMaterializePolicy's to not materialize missing assets.
[ui] Fixed an issue where global search and large DAGs were broken when using --path-prefix.
Schedule and sensor run submissions are now kept up to date with the current workspace, fixing an issue where a stale reference to a server would be used in some conditions.
[dagster-dbt] Fixed an issue where materializing dbt models with the same name as a dbt source would cause an error.
build_asset_reconciliation_sensor (Experimental) has been removed. It was deprecated in 1.3 in favor of AutoMaterializePolicy.
asset_key(s) properties on AssetIn and AssetDefinition have been removed in favor of key(s). These APIs were deprecated in 1.0.
root_input_manager and RootInputManagerDefinition have been removed in favor of input_manager and InputManagerDefinition. These APIs were deprecated in 1.0.
[dagster-pandas] The event_metadata_fn parameter on create_dagster_pandas_dataframe_type has been removed in favor of metadata_fn.
[dagster-dbt] The library has been substantially revamped to support the new @dbt_assets and DbtCliResource. See the migration guide for details.
Group names for dbt assets are now taken from a dbt model's group. Before, group names were determined using the model's subdirectory path.
Support for dbt-rpc has been removed.
The class alias DbtCloudResourceV2 has been removed.
DbtCli has been renamed to DbtCliResource. Previously, DbtCliResource was a class alias for DbtCliClientResource.
load_assets_from_dbt_project and load_assets_from_dbt_manifest now default to use_build=True.
The default assignment of groups to dbt models loaded from load_assets_from_dbt_project and load_assets_from_dbt_manifest has changed. Rather than assigning a group name using the model’s subdirectory, a group name will be assigned using the dbt model’s dbt group.
The argument node_info_to_definition_metadata_fn for load_assets_from_dbt_project and load_assets_from_dbt_manifest now overrides metadata instead of adding to it.
The arguments for load_assets_from_dbt_project and load_assets_from_dbt_manifest now must be specified using keyword arguments.
When using the new DbtCliResource with load_assets_from_dbt_project and load_assets_from_dbt_manifest, stdout logs from the dbt process will now appear in the compute logs instead of the event logs.
The dagit python package is deprecated and will be removed in 2.0 in favor of dagster-webserver. See the migration guide for details.
The following fields containing “dagit” in the Dagster helm chart schema have been deprecated in favor of “dagsterWebserver” equivalents (see migration guide for details):
[Dagster Cloud ECS Agent] We've introduced performance improvements that rely on the AWS Resource Groups Tagging API. To enable, grant your agent's IAM policy permission to tag:GetResources. Without this policy, the ECS Agent will log a deprecation warning and fall back to its old behavior (listing all ECS services in the cluster and then listing each service's tags).
DbtCliClientResource, dbt_cli_resource and DbtCliOutput are now being deprecated in favor of DbtCliResource.
A number of arguments on load_assets_from_dbt_project and load_assets_from_dbt_manifest are now deprecated in favor of other options. See the migration for details.
All public methods in the Dagster API now have docstrings.
The entirety of the documentation has been updated to now refer to the “Dagster webserver” or “Dagster UI” where “Dagit” was previously used for both entities.
