TopK now implements the Postgres wire protocol, so any Postgres client can run semantic search, hybrid search, and filtered retrieval as ordinary SQL.

This post evaluates how managed vector databases handle large-scale, production-like workloads—including millions of vectors, concurrent querying, real-world filtering, and continuous ingestion—using reproducible benchmarks across several leading providers.

At Data Council 2025, we introduced TopK, a unified cloud-native query engine that combines vector search, keyword matching, and flexible scoring in a single system. We demonstrated how TopK overcomes the limitations of traditional vector databases by supporting hybrid queries with custom ranking logic while maintaining high performance.
