MyScaleDB

The platform differentiates by treating vector search as native SQL operation, no separate API or query language. Write standard SQL with vector functions: SELECT * FROM table ORDER BY distance(embedding, query_vector) LIMIT 10. Built on ClickHouse columnar engine providing both vector similarity and analytical query performance. Multi-Scale Tree Graph (MSTG) algorithm enables efficient billion-scale vector search with filtering. Filtered vector search performs well without common accuracy degradation seen in other databases. For text-to-SQL: natural fit since both metadata queries and semantic search use same SQL interface. Limitations include ClickHouse operational complexity for self-hosted deployments.
