## What changed? Use current queueExclusiveHighReadWatermark to send catch up tasks when connections between clusters are new. ## Why? When a new pair of clusters is connected, we don't want sender to sync all previous tasks. Only new replication tasks are needed to be synced to receiver. ## How did you test it? Tested locally by checking the newly added logs. ## Potential risks ## Documentation ## Is hotfix candidate?
