Lakebase

Lakebase is a Databricks data engineering capability, introduced June 2025.

A fully managed, serverless Postgres (OLTP) database integrated into the Databricks platform, for building real-time transactional apps alongside lakehouse data.

  • It's a managed serverless Postgres for transactional apps - with instant database branching, so you can fork a whole database's worth of state in seconds.
  • In August 2025 the Compute section's 'OLTP Database' tab was quietly renamed 'Lakebase Postgres.'
  • You can debug it by talking to it - database issues and early warnings surface as Insights and you investigate them conversationally with Genie, all fed by database telemetry captured into Unity Catalog.

Limitations: Lakebase Postgres enforces per-project limits: a default of 20 concurrently active computes (the default branch is exempt, and Support can raise the limit), up to 500 branches per project, 500 Postgres roles and 500 databases per branch, 6 read replicas per branch, a 16 TB storage quota per branch that Support can also raise, up to 1000 projects per workspace, and a history retention window of at most 30 days.
