-------------------------------------
Summary: Improve support for Avro GenericRecord
Key: FLINK-6022
URL: https://issues.apache.org/jira/browse/FLINK-6022
Project: Flink
Issue Type: Improvement
Components: Type Serialization System
Reporter: Robert Metzger
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.
