Sink
In routing of inserts, a sink node is a node that stores the data in its store, as opposed to merely in its cache. Each node along the insert path decides whether it is a sink for the data as part of its routing decisions. In general, a node is a sink node if its location is closer to the data location than any of its peers, ignoring peers with too low a recent uptime (less than 40% in the past 48 hours (as of build 1233)), peers that are currently backed off, or otherwise unroutable peers.See also
