OLAP and OLTP converge as DuckDB extension decouples storage
A new PostgreSQL extension, pg_lake, offloads analytical queries to a vectorized DuckDB engine, isolating OLAP workloads from operational databases. The approach uses Apache Iceberg to decouple storage into cloud data lakes, preventing resource contention. This architecture allows intensive reporting queries without starving transactional connections on the same host.

The blurring of OLAP and OLTP boundaries is a practical step forward, but real-world adoption will depend on managing complexity and performance overhead at scale.
