Scenario: I have a three node cluster. One of the nodes goes offline (server dies, whatever). I bring up a new node with no data and it starts sync'ing with the other nodes in the cluster.
How do I know when this sync is complete and the new node has all the data? I'm dealing with thousands of DBs, so doing a doc count in each one isn't really feasible - at least not in a timely manner. Is there a log or API somewhere that indicates completion of data synchronization from a server perspective, not just individual DBs?
