databricks-lakebase-provisioned

You can provision a managed PostgreSQL instance on Databricks by creating and starting a Lakebase Provisioned instance with recommended capacity sizing. This returns a read_write_dns endpoint for connecting your notebooks and applications to the low-latency OLTP store.

You generate a short-lived OAuth token to securely connect your Databricks notebook to a PostgreSQL database. The setup includes patterns for automatic token refresh to maintain continuous access using one-hour credentials.

Yes, you can configure reverse ETL to sync a Unity Catalog Delta table to a provisioned PostgreSQL instance. This enables low-latency application queries against synced tables with continuous or triggered updates and token-managed access.

Yes, Databricks managed PostgreSQL supports LangChain applications by providing a low-latency OLTP store. You can persist agent and chat memory securely using OAuth tokens generated for your application connections.

Connections to Databricks managed PostgreSQL instances require SSL and use OAuth tokens for secure authentication. You must register the instance with Unity Catalog and implement periodic token refresh for one-hour credentials.

You manage the full lifecycle of a PostgreSQL instance on Databricks by creating, starting, stopping, and deleting Lakebase Provisioned instances. This includes recommended capacity sizing and Unity Catalog registration for secure application access.
