MonitorMatchFinder

trait MonitorMatchFinder extends AnyRef

In the Kafka Detective world, a MonitorMatchFinder is the interface responsible for determining what mesages in the given referenceWindow should be a match for the given testMessage. The match finder provides a find method that can return any one of a few different results.

Specifically, those results are:

  • A FoundMatch instance if a message that should match is found in the referenceWindow
  • A NoMatchFound instance if there should have been a message that would match, but there wasn't
  • An IgnoreMessage instance if, based on the key, we chose not to try to find a match

Each of these situations will be reported out to the various configured MonitorReporters by Detective.

Instances of this class should have a zero-arg constructor.
