tillrohrmann commented on issue #6755: [FLINK-10412] toString field in
AbstractID should be transient to avoid been serialized
URL: https://github.com/apache/flink/pull/6755#issuecomment-427753255
I created the resource files with the serialized `AbstractID` before
applying your changes. That way we still have serialized data of the old
`AbstractID` available.

> 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, pull-request-available, 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).
