Big Sack is a Java persistence mechanism that allows storage of key value pairs following the popular Big Data paradigms.

It has the convenience of Java SDK TreeMap and TreeSet classes and is used the same easy way, but it includes rollback through undo logging to checkpoint data so it does not wind up in an unknown state regardless of failures. Data storage in the exabyte...
