Target customers: 1. Businesses with read-heavy workloads 2. Businesses that have applications deployed across multiple zones and want to ensure that read requests are served by the closest available nodes within the same zone Features released: 1. A maximum of 9 read replicas are supported. 2. In dual-zone deployment mode, the number of read replicas in the primary and secondary zones can be flexibly configured. The maximum total number of nodes in the primary and secondary zones is 10 (1 master node and 9 read replicas). 3. In dual-zone deployment mode, each zone provides a separate endpoint, and each endpoint can process both read and write requests. On the premise of fully automatic intelligent read/write splitting, business applications in each zone can access the nearest read replicas in the zone. Write requests for services in the primary and secondary zones are automatically routed to the master node without manual intervention.
