------------------------------------
Summary: Improve Protobuf serialization performance
Key: FLINK-23712
URL: https://issues.apache.org/jira/browse/FLINK-23712
Project: Flink
Issue Type: Improvement
Components: Stateful Functions
Reporter: Igal Shilman
Assignee: Igal Shilman
Profiling allocations shows that a quarter of the allocations happens while
parsing Protobuf, this happens because the CodedInputStream/CodedOutputStream
allocate a 4kb buffer on construction. This can be easily avoided by caching
them.
