Vijay commented on CASSANDRA-4858:
----------------------------------
The problem is that we have to scan the nodes in token order so we dont break
the existing API's, if we do so then we are sending a lot more requests and
waiting for the response than the number of nodes.
Its highly unlikely we will be able to query contiguous ranges from the same
node. Still thinking of a better way....

>
> There are many cases where getRangeSlice creates more
> RangeSliceCommand than it should, because it always creates one for each range
> returned by getRestrictedRange. Especially for CL.ONE this does not take
> the replication factor into account and is potentially pretty wasteful.
> A range slice at CL.ONE on a 3 node cluster with RF=3 should only
> ever create one RangeSliceCommand.
