Dustin Vannoy covers one technique for CI/CD in Databricks:
Databricks Asset Bundles provides a way to version and deploy Databricks assets – notebooks, workflows, Delta Live Tables pipelines, etc. This is a great option to let data teams setup CI/CD (Continuous Integration / Continuous Deployment). Some of the common approaches in the past have been Terraform, REST API, Databricks command line interface (CLI), or dbx. You can watch this video to hear why I think Databricks Asset Bundles is a good choice for many teams and see a demo of using it from your local environment or in your CI/CD pipeline.
