While linting is an ancient practice in the software world, it's had slower adoption in the data world. SQLFluff is a cross-dialect SQL linter written in Python that ships with a simple command line interface (CLI), making it easy to incorporate into a CI/CD pipeline. If you're comfortable with the default conventions, then SQLFluff works without any additional configuration after installing it and will enforce a strongly opinionated set of formatting standards; setting your own conventions involves adding a configuration dotfile. The CLI can automatically fix certain classes of violations that involve formatting concerns like whitespace or uppercasing of keywords. SQLFluff is still new, but we're excited to see SQL getting some attention in the linting world.
