>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Coordination
>    Affects Versions: 1.7.0
>            Reporter: Zhu Zhu
>            Assignee: vinoyang

> 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).
