This post introduces database branching in Databricks Lakebase Postgres as a copy-on-write primitive that enables Git-like isolated database environments for development workflows.
•Traditional pg_dump-based cloning scales linearly with database size (minutes to hours), while Lakebase branches are created in seconds regardless of database size
•Lakebase separates compute from storage using a log-structured, versioned storage engine; branches share underlying data and only write changes separately (copy-on-write)
•Each branch gets its own Postgres connection string and independent compute endpoint, with idle branches auto-scaling to zero
•Key workflow patterns include one branch per developer, one per pull request (integrated with Vercel/Netlify preview deployments), one per CI test run, and ephemeral environments for AI agents
•Time travel is supported natively, allowing branches to be created from any past point within a configurable restore window for instant point-in-time recov
