             Summary: Introduce ExecNodeContext.generateUid()
                 Key: FLINK-25932
                 URL: https://issues.apache.org/jira/browse/FLINK-25932
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Timo Walther


FLINK-25387 introduced an {{ExecNodeContext}} which contains all information to generate unique and deterministic identifiers for all created {{Transformation}}.

This issue includes:
- Add {{ExecNodeContext.generateUid(operatorName: String): String}}
- Go through all ExecNodes and give transformations a uid. The name can be constant within the ExecNode such that both annotation and method can use it.
- We give all transformations a uid, including stateless ones.
- The final UID should look like: {{13_stream-exec-sink_1_upsert-materializer}}
