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
