It supports PostgreSQL 17 and 18, and installs as bm25_native . CREATE EXTENSION bm25_native; CREATE INDEX docs_bm25 ON docs USING bm25_native (body); SELECT id, bm25_score(ctid) AS score FROM docs WHERE body @@@ 'quick fox' ORDER BY body &@@ 'quick fox' LIMIT 10; @@@ selects the matching rows and &@@ orders them by relevance.
Database Engine & Storage Subsystem Architecture
From an OLTP/OLAP systems architecture, storage tiering, and data durability perspective: - **Zero-Vendor Lock-in Formats:** Leveraging open specifications (e.g. Parquet, Iceberg) ensures multi-engine interoperability without ingestion lock-in. - **Vector & In-Memory Throughput:** Modern memory layouts and SIMD-accelerated execution pipelines minimize latency in real-time retrieval. - **Distributed Resiliency:** Decoupled storage and compute layers enable elastic horizontal scaling with strict ACID guarantees.
Impact on the Open Ecosystem
Empowers data engineers with open, self-hosted alternatives to monopolistic cloud database providers.
