Streambed, a new open-source tool, enables real-time streaming of PostgreSQL databases to Apache Iceberg tables on S3. The project supports Postgres Wire protocol for direct compatibility.
Streambed bridges PostgreSQL and cloud data lakes by streaming database changes directly to Iceberg, an open table format optimized for analytics. The tool leverages Postgres Wire protocol support, allowing it to act as a native Postgres endpoint while transforming and routing data to S3.
Key features include continuous synchronization of Postgres tables, support for schema evolution, and integration with S3-based data lakes. The project targets teams managing analytical workloads who need to decouple their transactional databases from data warehouse infrastructure.
Streambed addresses a common data pipeline challenge: moving production database changes to cloud storage without custom connectors or complex ETL orchestration. By implementing Postgres Wire compatibility, the tool can integrate into existing database tooling and applications with minimal friction.
The GitHub project has attracted 101 points on Hacker News with 26 comments, indicating developer interest in simplified data streaming solutions. The project is available on GitHub under the Streambed repository.
