Does RDS for MySQL Support Sharding and Read/Write Splitting?

Yes. RDS for MySQL supports sharding and read/write splitting.

  • RDS works with Distributed Database Middleware (DDM) to provide sharding, allowing you to easily scale up your database.
  • Up to five read replicas can be created for a primary DB instance. Read replicas and DB instances are connected through separate IP addresses.

    If you want to access your instance and read replicas using a unified read/write splitting address, enable read/write splitting first.
