Description
Locality groups are a neat feature, but there is no reason to limit partitioning to column families. Data could be partitioned based on any criteria. For example if a user is interested in querying recent data and ageing off old data partitioning locality groups based in timestamp would be useful. This could be accomplished by letting users specify a partitioner plugin that is used at compaction and scan time. Scans would need an ability to pass options to the partitioner.
