      Description

      We basically need 2 brokers to compare their current state and ensure they are both in exactly the same state.

      e.g.

      • both brokers checkpoint
      • they perform a database merge
      • they can now continue being a master-slave pair

      Maybe the easiest implementation is to find the list of all unique message producers then perform a 'sequence-range' comparison.

      e.g.

      broker1:
      producer1: 1-100, 102-142, 145
      ...

      broker2:
      producer1: 1-12

      then we send from broker1 to broker2 producer1: 13-100, 102-142, 145
