BaikalDB is a distributed HTAP (hybrid transactional/analytical processing) database developed by Baidu, written in C++ and using Raft for consensus. It is MySQL protocol compatible, supports petabyte-scale structured data, and offers full-text search via inverted indices.

Use cases

• migrate a MySQL workload to a horizontally scalable distributed database
• run transactional and analytical queries on the same petabyte-scale dataset
• add full-text fuzzy search to tables with FULLTEXT KEY indexes
• store and query hundreds of millions of rows with second-level aggregations
• self-host a distributed SQL database with strong consistency via Raft

When to choose

• you need MySQL compatibility but outgrow a single MySQL instance
• you want mixed OLTP and OLAP workloads in one system
• you need built-in full-text search alongside SQL
• you require petabyte-scale structured data storage with real-time reads and writes

When to avoid

• you need a fully managed cloud database
• your data fits comfortably in a single MySQL or PostgreSQL instance
• you depend on advanced MySQL features or ecosystem tooling not supported by BaikalDB's dialect
• you need non-Linux production deployments or broad community support
