Installing dbt-vertica

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-vertica

Configuring dbt-vertica

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