{"slug":"best-mysql-compatible-htap-databases","title":"Best MySQL-compatible HTAP databases","question":"What are the best MySQL-compatible HTAP databases in 2026?","verdict":"As of 2026-08-06, ChatGPT, Claude and Gemini collectively rank TiDB #1 for mysql-compatible htap databases on ModelsAgree — unanimous among the 3 models that have answered. The models' case: Best overall balance of mature distributed transactions, horizontal scale, strong-consistent TiFlash columnar analytics, automatic row/column plan selection, and both. The models' main caveat: It is not drop-in MySQL—triggers, stored procedures, UDFs, and other semantics remain compatibility gaps. The strongest alternative is MySQL HeatWave — Native MySQL/InnoDB behavior, automatic analytical offload, continuous change propagation, strong managed operations, and excellent value for existing.
