Read/Write Splitting Plugin + RDS Proxy

[fkjaekel]

I have configured the RDS Proxy with a read/write endpoint and a read only endpoint. I'd like to know if the Read/Write Splitting Plugin is compatible with this setup.

Hi @fkjaekel, we have not fully tested the Read/Write Splitting plugin with RDS Proxy and we do not recommend using it in production.

RDS Proxy transparently re-routes requests to a single database instance, and it decides which database instance to use based on its criteria. Since RDS Proxy is handling the switching between different instances, it reduces the impact of using the Read/Write Splitting plugin and its several host selection strategies.

Since you have a read/write endpoint and a read-only endpoint similar to the reader and writer cluster endpoints, using just the Read/Write Splitting plugin may work for basic workflows. Using other plugins on top of this set up may cause unpredictable side effects, therefore we do not recommend using it in production.
