Explore cracker style indexes to optimize tuple reconstruction costs in column stores. Ref:

n-orm offers a simple persistence layer for Java. Targeted stores are "no-sql" as the framework assumes a column-oriented like storage data model. The framework makes use of annotations, and offers a very simple query language, simple enough to be very efficient, and too simple to let a model not to be efficient... ;-) Current stores are HBase, MongoDB and Redis, though new driver should be simple to implement. Expectations on a data stores are that they can handle sorted maps (sorted according to their String key) and atomic increments.
