--------------------------------------
Summary: Processing for Avro generated classes is very slow
Key: FLINK-11076
URL: https://issues.apache.org/jira/browse/FLINK-11076
Project: Flink
Issue Type: Bug
Reporter: Maciej Bryński
I tested Flink processing with Avro generated Pojo classes and most of the time
is spent in serialization / deserialization.
The problem is that those classes are internally serialized with Avro
serializer instead of Pojo serializer.
