dbt-ditto
same as above. dbt-ditto propagates column documentation down the dbt graph and
writes it back into your schema YAML. It reads the manifest.json and
catalog.json dbt already wrote, so it needs no dbt, no Python and no warehouse
connection — a single static Go binary.
uv add dbt-ditto # or: pip install dbt-ditto
dbt-ditto inherit path/to/project
What it does
- Inherits descriptions, meta and tags down the DAG, and syncs the column list, data types and schema-file placement against the catalog.
- Reproduces dbt-osmosis byte for byte, reading your existing
+dbt-osmosis:path templates as-is. No migration. - Crosses project boundaries for dbt-loom setups, reading
dbt_loom.config.ymlso the upstream list is not maintained twice. It does not replace loom: loom injects nodes at dbt runtime, ditto runs afterwards over artifacts on disk. - Documents source tables, which inheritance can never reach, from warehouse comments, backfill from downstream, or source providers that ask the warehouse directly.
- Takes explicit instructions for renamed columns, and has a
--checkmode that fails CI on stale documentation without writing.
An order of magnitude faster than dbt-osmosis, never re-parsing the project (benchmark).
