Description

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.
