[jira] [Closed] (FLINK-11076) Processing for Avro generated classes is very slow

     [ https://issues.apache.org/jira/browse/FLINK-11076?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Till Rohrmann closed FLINK-11076.
---------------------------------
    Resolution: Not A Problem

I think it is working as intended. Avro types are serialized using the Avro serializer. Please re-open if you disagree.

>            Priority: Major
>
> 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.
