jenswaage opened a new pull request, #48645: URL: https://github.com/apache/spark/pull/48645
### What changes were proposed in this pull request? Add a note on compatibility issues between the `from_avro` function and the Confluent Schema Registry. ### Why are the changes needed? Avro data produced by the Confluent Schema Registry serializer adds extra bytes to the serialised data, and the `from_avro` function lacks built-in support for this. This can lead to some very confusing errors if one is not aware of this technical detail. There is a [thread on StackOverflow](https://stackoverflow.com/questions/48882723/integrating-spark-structured-streaming-with-the-confluent-schema-registry) that discusses this, but a note in the official docs can be easier to discover for users that are looking for help with this issue. ### Does this PR introduce _any_ user-facing change? Yes, it adds a section to the Apache Avro Data Source Guide ### How was this patch tested? Manually by inspecting generated docs ### Was this patch authored or co-authored using generative AI tooling? No -- This is an automated message from the Apache Git Service.
