## What it is
Gaea is a MySQL-protocol database middleware proxy developed by Xiaomi's B2C dev team. It provides sharding (database and table partitioning), SQL routing, read-write splitting, and multi-tenant management, compatible with MyCat and Kingshard routing schemes.

## Use cases
- shard mysql tables across multiple databases
- split mysql reads and writes across replicas
- proxy mysql connections with load balancing
- manage multi-tenant mysql clusters
- route sql queries to correct shards
- filter and intercept sql statements
- monitor slow sql queries

## When to choose
- you need transparent mysql sharding without changing application code
- you want read-write splitting with replica load balancing
- you need multi-tenant mysql proxying with hot config reload
- you want mycat or kingshard compatible routing

## When to avoid
- you use a database other than mysql
- you need distributed transactions, which are still on the roadmap
- you prefer built-in database sharding like vitess-managed clusters or cloud-native solutions

## Facets
- artifact type: service
- maturity: active
- function: database, middleware, routing, caching, monitoring
- domain: databases, backend, microservices, self-hosted
- platform: go, self-hosted
- tags: mysql-proxy, sharding, read-write-splitting, sql-routing, database-middleware, multi-tenant, linux, docker
