Does MySQL Support Sharding and Read/Write Splitting?
Updated at: Jun 09, 2021 GMT+08:00
Yes. RDS supports sharding and read/write splitting.
- Distributed Database Middleware (DDM) provides sharding to remove database capacity and performance bottlenecks.
- Up to five read replicas can be created for a primary DB instance. Read replicas and DB instances are connected through separate IP addresses.
