      splitVector is used by sharding and returns the split points for a collection. It shows pretty impressive performance while doing so. There are many cases where it can be extremely useful to know to split points of a collection, for example:

      • to subdivide workload accross application threads
      • to subdivide workload for map reduce

      There is no easy alternative for the application in case it is not aware of the distribution of a key.
      In the context of sharding, mongos could just return the chunk ranges.
      This should be made available to a 'read' or 'readWrite' application user.
      It seems also that the hadoop connector currently relies on these things, so we should make it properly supported.
