A fully managed, Postgres-compatible OLTP database built into Databricks — low-latency transactions and feature serving that sit right next to your lakehouse.
Lakebase is a serverless, Postgres-compatible OLTP database where storage and compute scale independently, with copy-on-write branching and two-way sync to Unity Catalog Delta tables.
The lakehouse is great at analytics but not at millisecond, row-level reads and writes. Lakebase gives you a real transactional Postgres for app backends, online feature stores, and agent state — without standing up and operating a separate database, and without ETL gymnastics to move data between your operational store and the lakehouse.
Standard Postgres wire protocol and SQL (PG 16/17) — connect with psql, psycopg, DBeaver, or any Postgres driver; OAuth token is the password over SSL.
Compute (endpoints, sized in compute units) autoscales 0.5–112 CU and scales to zero; durable storage lives independently, so you pay for compute only while it serves.
Copy-on-write branches clone a database instantly for dev, testing, or CI/CD — including point-in-time branches for recovery — without copying the data.
Sync a Unity Catalog Delta table into Postgres for low-latency serving, in snapshot, triggered, or continuous mode via a managed Lakeflow pipeline.
Capture Postgres changes back into Unity Catalog Delta tables (CDC) so operational writes land in the lakehouse for analytics — Public Preview.
Backs Databricks Apps, online feature stores for ML model serving, and AI agent state — transactional reads/writes co-located with governed lakehouse data.
SQL · standard Postgres against Lakebase-- ordinary Postgres DDL/DML — no Databricks dialect
CREATE TABLE orders (
id bigint PRIMARY KEY,
customer text NOT NULL,
amount numeric(12,2),

);
INSERT INTO orders (id, customer, amount)
VALUES (1, 'acme', 42.00);

SELECT * FROM orders WHERE id = 1;
