Databricks Unveils 'Lakebase' Serverless Postgres
Databricks has unveiled Lakebase, a serverless version of Postgres built on top of its lakehouse storage architecture. The new offering is designed for building agentic applications by separating compute and storage to enable instant scaling. Lakebase aims to combine the transactional capabilities of a traditional database with the scalability of a data lakehouse.
The foundation of Lakebase comes from Databricks' acquisition of Neon, a serverless Postgres company, for approximately $1 billion in May 2025. This was followed by the acquisition of Mooncake in October 2025 to improve the integration of PostgreSQL databases with the lakehouse architecture. The technology is explicitly aimed at serving AI-native applications; Neon reported that four out of every five databases on its platform were created by AI agents, not humans. By separating compute from storage, Lakebase addresses the architectural bottleneck of traditional databases where a single heavy query can slow down all live operations. This serverless design allows compute resources to scale automatically based on load and even scale to zero when inactive, with customers billed for consumed "Capacity Unit hours". This approach is designed to eliminate the need for ETL and CDC pipelines between transactional and analytical systems. The service is now Generally Available on AWS and in public preview on Azure, with Google Cloud support planned for later this year. It supports up to 8TB of storage per instance and runs on Postgres 17, which includes the pgvector extension for AI-driven search capabilities. For governance, Lakebase integrates with Databricks' Unity Catalog to provide unified access control and auditing across the platform. Key developer features include instant database branching, allowing teams to create isolated copies of production data for testing in seconds without duplicating the underlying data. The platform also offers automated backups and point-in-time recovery, enabling restoration of a database's state to a specific millisecond within a retention window. For organizations in regulated industries, SOC2 and HIPAA certifications are planned for early 2026.
