Piotr Kołaczkowski commented on CASSANDRA-4871:
-----------------------------------------------
And why the patch file has a different number than the ticket? Is it right
patch file?
> get_paged_slice does not obey SlicePredicate

> When experimenting with WideRow support, I noticed that it is not possible to
> specify a bounding SlicePredicate. This means that, no matter what you may
> wish, the entire Column Family will be used during a get_paged_slice call.
> This is unfortunate, if (for example) you are attempting to do MapReduce over
> a subset of your column range.
> get_paged_slice should support a SlicePredicate, which will bound the column
> range over which data is returned. It seems like this SlicePredicate should
> be optional, so that existing code is not broken--when the SlicePredicate is
> not specified, have it default to going over the entire column range.
