Streambed Streams Postgres Data to Iceberg for Analytical Queries
TL;DR. Streambed offers an engine to stream Postgres WAL changes to Apache Iceberg on S3, allowing analytical queries without application changes. - It uses logical replication to write Parquet files to S3 and commits Iceberg metadata, supporting updates and deletes. - A built-in query server exposes Iceberg tables over the Postgres wire protocol using embedded DuckDB. - This design offloads analytical workloads from production databases directly to Iceberg data lakes. - The system integrates seamlessly with existing Postgres clients like psql.
- Streambed streams Postgres WAL to S3 as Parquet files with Iceberg metadata via logical replication.
- It offloads analytical queries from production databases without requiring application modifications.
- A Postgres wire protocol-compatible query server allows connection using standard Postgres clients.
- The architecture uses DuckDB for embedded query processing against Iceberg tables.
- The tool simplifies data warehousing by enabling direct querying of Iceberg data through a familiar interface.
