----------------------------------
Summary: Move the serialization of ShuffleDescriptorGroup out of
the RPC main thread
Key: FLINK-33532
URL: https://issues.apache.org/jira/browse/FLINK-33532
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Reporter: Yangze Guo
Assignee: Yangze Guo
Fix For: 1.19.0
Currently, the serilization of ShuffleDescriptorGroup would happen in the RPC
main thread even for light jobs. We propose to move it out of the rpc main
thread. For heavy jobs, it still worth to cache the serialized value for memory
efficiency.
