> Currently when HH is enabled, hints are stored, and when a node comes back, we begin
sending that node data. We do a lookup on the local node for the row to send. To help reduce
read load (if a node is offline for long period of time) we should store the data we want
forward the node locally instead. We wouldn't have to do any lookups, just take byte[] and
send to the destination.
