> We have encountered a critical case from online services. we have the data pipeline: (producer) -> (kafka) -> (flink consumer job), and all those records are encoded in AVRO format. Once the producer changed the AVRO schema , says adding an extra column to the existing schema and writing few data into the Kafka.
> Then the downstream flink job crashed with the following stacktrace:
