Yun Gao reassigned FLINK-23681:
-------------------------------
Assignee: Yun Gao
> Rename the field name of OperatorIDPair to avoid the confusion
> --------------------------------------------------------------
>
> Key: FLINK-23681
> URL: https://issues.apache.org/jira/browse/FLINK-23681
> Project: Flink
> Issue Type: Bug
> Reporter: Yun Gao
> Assignee: Yun Gao
> Priority: Major
>
> For the OperatorIDPair, currently the name might have some misleadings: the
> generatedOperatorID is based on both uid and the nature order if uid is not
> set (StreamGraphHasherV2), and the userDefinedOperatorID is based on the
> uidHash (StreamGraphUserHashHasher). The second one should only be used if
> users forget to set a customized uid on the first run, but want to restore
> from the state, then users could directly specify the uidHash and it will be
> used as the operator id directly.
>
> Thus the current name might cause the confusion that it is easily to think
> they are based on the nature order or the uid field. Thus we might rename the
> fields to be more clear.
