Technicals

Q: Can write-only instances and read-only replicas be created?
A: Yes, but the write-only instances are read-write. It allows both reads and writes.

Q: Does CCX support the use of a Proxy or Load Balancer (for example, if there are 2 or more Read Replica instances, then Read can be load-balanced across multiple instances)?
A: DNS is used to facilitate this. However, the user can create his load balancer (such as HAProxy or ProxySQL) and connect to the database service. A load balancer should be placed as close as possible to the user’s application. We recommend that the end-user manages the load balancer.
