Description

Currently, the CollectResultIterator relies on the operator ID to send REST requests to the JM for querying results. However, with the introduction of Stream Graph submission, the Job Graph will be compiled and generated within the JM, resulting in the client being unable to access the operator ID.

To resolve this issue, we intend to refactor CollectResultIterator to remove its dependency on the operator ID and utilize an alternative UUID instead.
