Subject row cache during bootstrap
Date Fri, 06 Aug 2010 23:17:49 GMT
the way i understand how row caches work is that each node has an
independent cache, in that they do not push there cache contents with other
nodes.  if that the case is it also true that when a new node is added to
the cluster it has to build up its own cache.  if thats the case i see that
as a possible performance bottle neck once the node starts to accept
requests.  since there is no way i know of to warm the cache without adding
the node to the cluster.  would it be infeasible to have part of the
bootstrap process not only stream data from nodes but also cached rows that
are associated with those same keys?  that would allow the new nodes to be
able to provide the best performance once the bootstrap process finishes.
