   I see the routing issue now. On a single server, it can have up to one 
consuming segment per partition; but on multiple servers serving the same 
segment, they might not finish sealing the segment at the same time. On the 
broker side, it might show as multiple consuming segments.
   The routing fix in your commit can solve the inconsistency, but might also 
cause hotspot server because all the queries will be routed to the servers 
which finish the segment sealing first. To address this, one solution would be 
to also enhance the instance selector so that it queries the consuming segment 
on a server only when the server is picked to serve the last completed segment.
