^ We allow mapping from partition X from source to partition Y to destination. We should remap this when we are pulling destination offsets for resetting consumer offsets.
In a scenario where kaf-relay is in failover mode and there is a topic called "topicA" present on both serverA and serverB (individual kafka brokers), if the messaging flow into serverA becomes stuck due to some issue, we require the capability to switch over to serverB if the lag on serverA exceeds a certain threshold.
Filter plugin allows us to filter messages when we forward from one cluster to another. But, using this feature in tandem with failover mode is of little use and can lead to improper states when resetting offsets.
