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.

    After enabling read/write splitting, you can use a single read/write splitting address, which can be obtained on the Read/Write Splitting page.

    For details, see Configuring Read/Write Splitting.
