[jira] [Updated] (FLINK-6022) Don't serialise Schema when
serialising Avro GenericRecord
[ https://issues.apache.org/jira/browse/FLINK-6022?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Till Rohrmann updated FLINK-6022:
---------------------------------
Fix Version/s: (was: 1.5.0)
1.5.1
> Don't serialise Schema when serialising 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
> Assignee: Stephan Ewen
> Priority: Major
> Fix For: 1.5.1
>
>
> 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.
