Range Queries in RP on SCF in 0.7 with UUID SCs

Is it possible to perform paginated queries using Random Partitioner in 0.7 with Super Column Families whose Super Columns are UUID's? I don't believe it is, based on this article: http://ria101.wordpress.com/2010/02/22/cassandra-randompartitioner-vs-orderpreservingpartitioner, and my attempts

look at the Beta 2 java thrift interface in Cassandra.java, line 544 is not in recv_get_slice. May be nothing. Perhaps check the server for an error and double check your client is coded for beta 2. Hope that helps. Aaron On 15 Oct, 2010,at 12:32 PM, Frank LoVecchio fr...@isidorey.com
