Hey folks, I’m wondering about this old Jira and PR from 2017 (https://issues.apache.org/jira/browse/AVRO-2078). It’s a bit scary to work with decimal types in Avro from Java since changes in precision and scale are not considered incompatible but will royally mess up the data if introduced. We have implemented our own validation for this and I was considering adding that as a PR when I found this one.
The Avro spec says “For the purposes of schema resolution, two schemas that are decimal logical types match if their scales and precisions match”, so that’s pretty clear IMO. My question is basically: Is there a chance of getting this validation merged? If not as-is, then maybe modified in some way (like making logical types validation configurable). I’m happy to help with the PR or create a new one if needed. Best, Katrin
