JVM or python just for the ecosystem. kafka, debezium, workflow engines(camunda), ORMs etc - java libraries might not be as nice to use as ruby gems but some are really rock solid for your use-case.

But that being said, anything really - rails/node etc most would work just fine for your use-case

I didn't find debezium production ready when I tried it about a year ago. If I recall, no cascading deletes and it can't handle 0000-00-00 dates due to "some java limitation" (maybe in the kafka producer? I honestly forget) and when a dev on my team made a PR to the debezium project it was not merged because the team felt it was outside of scope for debezium. Also, because of implementation details, it will never do cascades.

End result was a lot of wasted effort. It worked for one team who didn't have those requirements and even then they spent more time than they should have and then ripped out debezium and went with standard mysql replication as it doesn't require the entire kafka stack.

My experience with it reaffirmed my standard technique of data migration of write to both and move reads over when ready.
