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
