Given that it was in our bugzilla I let myself use some Riak-internals jargon without explanation. In this context, a partition is a logical segment of the ring space, managed by a vnode process on a given physical host. There is a 1-to-1 mapping between a vnode process and a partition. The idea is that right now the bitcask backend stores all data in a given partition together in a single bitcask instance. The alternative backend under discussion would break that up, such that within a partition (and thus in each vnode), there would be a bitcask instance for every bucket that had any data. Does that help to clarify? -Justin _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
