Generalize locality groups
--------------------------
Key: ACCUMULO-452
URL: https://issues.apache.org/jira/browse/ACCUMULO-452
Project: Accumulo
Issue Type: New Feature
Reporter: Keith Turner
Fix For: 1.5.0
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.
