Secondary indexing and order clauses

Hi guys,
  Now that dynamic composite have been introduced as part of cassandra
core, has any thought been given to implementing "order by" semantics to
secondary indexing?  The dynamic composite allows asc/desc order sorting
of each component in the composite, allowing for mixed asc/desc order in
secondary indexes at the cost of additional disk space.

Thanks,
Todd

Hi Todd,

The Lucene secondary index will support sorting fairly easily (eg, out of
the box).  See: CASSANDRA-2915
