How to troubleshoot connection errors in setting up a sink into MySQL in a Kubernetes environment of RisingWave?
I am encountering a connection error while trying to create a sink into MySQL in a Kubernetes environment of RisingWave. The error message indicates a failed connection to the connector endpoint. I have verified that the connector node is deployed in the cluster. How can I troubleshoot and resolve this connection error?

-
Verify if the
connectoris enabled by checking the replicas configuration. -
Ensure that the network connectivity is good, both from outside to Kubernetes and within the Kubernetes cluster.
-
Deploy the connector node in the cluster and confirm its availability.
-
Check the database endpoint configuration to ensure it is pointing to the correct instance.
-
Consider testing the JDBC sink with a self-hosted MySQL to isolate the issue.
-
If using AWS Aurora (MySQL), note that it may still be in the research phase, so additional testing and verification may be required.
-
For AWS Aurora Postgres CDC, it is recommended to test it separately as thorough testing may not have been conducted yet.
