Yangze Guo reassigned FLINK-33532: ---------------------------------- Assignee: dizhou cao (was: Yangze Guo) > 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: dizhou cao > Priority: Major > 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. At the same time we need to make the serialization thread > pool configurable. -- This message was sent by Atlassian Jira (v8.20.10#820010)
