Documentation

Aims

dbt-bouncer aims to:

• Provide a 100% configurable way to enforce conventions in a dbt project.
• Be as fast as possible, running checks against dbt artifacts.
• Be as easy as possible to use, with a simple config file written in YAML or TOML.
• Be as flexible as possible, allowing checks to be written in Python.
• Provide immediate feedback when run as a pre-commit hook or as part of a CI pipeline.

4. Run dbt-bouncer:

   $ dbt-bouncer run
