  • GitHub repo: pingcap/dbt-tidb
  • PyPI package: dbt-tidb

  • dbt Cloud support: Not Supported

Installing dbt-tidb

Use pip to install the adapter. Before 1.8, installing the adapter would automatically install dbt-core and any additional dependencies. Beginning in 1.8, installing an adapter does not automatically install dbt-core. This is because adapters and dbt Core versions have been decoupled from each other so we no longer want to overwrite existing dbt-core installations. Use the following command for installation:

python -m pip install dbt-core dbt-tidb

Configuring dbt-tidb

For TiDB-specific configuration, please refer to TiDB configs.
