MyScaleDB is an open-source SQL-native vector database achieving 98% accuracy at 100+ QPS, built on ClickHouse for analytical performance. Free Community tier available; pricing for managed service varies. 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. Page should cover: SQL vector syntax, MSTG algorithm explanation, filtered search capabilities, ClickHouse foundation benefits, comparison with pgvector and dedicated vector DBs, and use cases for SQL-native vector search.
