2I uses document partitioning, so all queries must go to all nodes (or, rather, enough nodes that it covers your entire data set (so for N=3, around a third of your nodes)). Any and all index information pertaining to a particular document is stored right alongside the document itself. Riak Search uses term partitioning, so a query for prop=value will only need to look in a single index. > 2. What is the reliability N,R,W / replication / failover properties of these > indexes?

I don't know about your other questions. -- Soren Hansen | http://linux2go.dk/ Ubuntu Developer | http://www.ubuntu.com/ OpenStack Developer | http://www.openstack.org/ _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
