Sharding EMEA
This task is to come up with a model for what a consolidation/defragmentation algorithm for a sharded cluster would look like and to evaluate whether the existing consolidate_ns_chunks.js script fulfills that model.
As part of this ticket we should evaluate whether we could perform most of the merges prior to moving data around so that the effect of refreshes for clusters with large number of chunks can be kept to a minimum.
