Hi guys,
=A0 Now that dynamic composite have been introduced as part of cassandra co= re, has any thought been given to implementing "order by" semanti= cs to secondary indexing?=A0 The dynamic composite allows asc/desc order so= rting of each component in the composite, allowing for mixed asc/desc order= in secondary indexes at the cost of additional disk space.
