> Key: FLINK-10412
> URL: https://issues.apache.org/jira/browse/FLINK-10412
> Project: Flink
> Issue Type: Bug
> Components: Distributed Coordination
> Affects Versions: 1.7.0
> Reporter: Zhu Zhu
> Assignee: vinoyang
> Priority: Major
> Labels: deploy,deployment, serialization
>
> The toString field in AbstractID will be serialized currently, which makes RPC messages body like InputChannelDeploymentDescriptor and PartitionInfo larger (50%+).
> It adds more pressure to JM memory especially in large scale job scheduling (10000x10000 ALL-to-ALL connection).
