[jira] [Created] (FLINK-20699) Feedback invocation_id must not be constant.

Igal Shilman created FLINK-20699:
------------------------------------

             Summary: Feedback invocation_id must not be constant.
                 Key: FLINK-20699
                 URL: https://issues.apache.org/jira/browse/FLINK-20699
             Project: Flink
          Issue Type: Improvement
          Components: Stateful Functions
    Affects Versions: statefun-2.2.1, statefun-2.3.0
            Reporter: Igal Shilman
            Assignee: Igal Shilman
             Fix For: statefun-2.2.2


To support iteration in StateFun (we call them feedback) we use a key (FeedbackKey) that connects a feedback producer with a feedback consumer. The feedback broker will connect a consumer with a producer given a supplied key.

A key has two complements: pipeline name and an invocation id,

To guard against accidental reuse, the invocation id part should be unique.
