Stephan Ewen commented on FLINK-6022:
-------------------------------------

I think this should be resolved, because Generic records and all non-specific 
records should go through the ReflectDatumReader/Writer.

However, would be great if someone from the people that originally opened the 
ticket could comment on this.

> Currently, Flink is serializing the schema for each Avro GenericRecord in the 
> stream.
> This leads to a lot of overhead over the wire/disk + high serialization costs.
> Therefore, I'm proposing to improve the support for GenericRecord in Flink by 
> shipping the schema to each serializer  through the AvroTypeInformation.
> Then, we can only support GenericRecords with the same type per stream, but 
> the performance will be much better.
