Cetus is a high-performance MySQL proxy middleware written in C that provides transparent routing between applications and backend MySQL servers. It offers read-write splitting and data sharding editions with connection pooling, distributed transaction support, and monitoring, enabling horizontal scaling and high availability at the database layer.

Use cases

• proxy mysql connections transparently
• split mysql reads and writes across replicas
• shard mysql tables horizontally
• pool backend database connections
• scale mysql horizontally without changing application code
• run distributed transactions across sharded mysql servers
• monitor and manage mysql backend health

When to choose

• you need transparent read-write splitting for mysql
• you want to shard mysql data with minimal application changes
• you need connection pooling and sql routing in front of mysql backends
• you require xa-style distributed transactions across shards

When to avoid

• you use postgres or another non-mysql database
• you want a fully managed cloud database proxy
• your project needs a very actively developed tool with frequent releases
• you need a proxy written in a memory-safe language
