Thanks @stevenzwu for bringing this up. It's indeed an problem for flink streaming reader because it depends on the java serialization in [StreamingReaderOperator](https://github.com/apache/iceberg/pull/1793/files#diff-22513db68a66d835391d1dad5b0b95ed776dbcc3df7c8df7df5450930f367893R67) now, it's easy to crash when we upgrade iceberg lib version (which changes the CombinedScanTask classes) and restart the flink job. I'd prefer to define the avro schema in `BaseCombinedScanTask` which is similar to `BaseDataFile`, then we could maintain the binary bytes which is serialized by avro approach to flink state backend. Let me evaluate the work. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
