Dagster Files

New

• Updated the cursoring logic of AutomationCondition.since()/AutomationCondition.newly_true() to make them retain access to their stored data in a wider range of scenarios where the underlying condition structure is changed.
• Added a --use-active-venv method to a variety of dg commands. (Thanks, @cmpadden!)
• The build_defs_at_path and load_component_at_path methods on the ComponentLoadContext class have been renamed to build_defs and load_component respectively. The previous names have been preserved for backcompat.
• The template variables available in the default resolution scope for Components have been reorganized / expanded:
• {{ automation_condition.on_cron(...) }} -> {{ dg.AutomationCondition.on_cron(...) }}
• **new: ** All AutomationCondition static constructors may be accessed via the dg context, e.g.:
  • {{ dg.AutomationCondition.on_missing() & dg.AutomationCondition.in_latest_time_window() }}
• **new: ** All PartitionsDefinition subclasses are now available via the dg context, e.g.:
• {{ dg.StaticPartitionsDefinition(['a', 'b', 'c']) }}
• {{ dg.DailyPartitionsDefinition('2025-01-01') }}
• {{ project_root }} -> {{ context.project_root }}
• {{ build_definitions_at_path(...) }} -> {{ context.build_defs(...) }}
• {{ load_component_at_path(...) }} -> {{ context.load_component(...) }}
• All previous template vars will continue to work as before for backcompat.
• [ui] Improve browser performance for large asset graphs.
• [dagster-snowflake] Added create_snowpark_session() which provides a convenient way to create a Snowpark session. (Thanks, @stevenayers!)
• [dagster-snowflake] Added get_databases(), get_schemas(), get_tables(), get_views(), get_pipes() & get_stages() which provide a pythonic interface for Snowflake introspection. (Thanks, @stevenayers!)
• [dagster-dbt] You can now override the op_config_schema property on the DbtProjectComponent to customize how your dbt execution can be configured at runtime.

Bugfixes

• Added the ability to execute refreshes of embedded and published datasources when using the TableauComponent.
• Fixed a bug in asset partitions where the partition range selector would sometimes stop working.
• [dagster-dbt] Fixed a FileExistsError on Windows when reloading dbt project definitions by ensuring the local project directory creation handles pre-existing directories. (Thanks, @Jongwan93!)
• [dagster-dbt] Fixed an issue introduced in version 1.12.2 that caused the DbtProjectComponent to not produce asset checks for tests on dbt sources. (Thanks, @stevenayers!)

Documentation

• Added documentation for the community dagster-slurm integration. (Thanks, @geoHeil!)
