If I'm not mistaken cassandra has been providing support for keyrange queries also on RP.

However when I try to define a keyrange such as, start: (key100, end: key200) I get an error like:
InvalidRequestException(why:start key's md5 sorts after end key's md5.  this is not allowed; you probably should not specify end key at all, under RandomPartitioner)

How can I utilize cassandra to get a keyrange in RP?
