Yes. MySQL works with the Distributed Database Middleware (DDM) service to support sharding and read/write splitting.
- The DDM service supports sharding. MySQL uses the DDM service to expand storage space or performance.
- A maximum of five read replicas can be created for a MySQL single or primary/standby DB instance. Read replicas and single or primary/standby DB instances use independent IP addresses. If you want to use a unified address for read/write splitting, you need to use the DDM service or build the SQL-proxy middleware.
