ObjectGrid is a distributed coherent cache. It allows data to be partitioned and optionally replicated to a grid of computers that can be thousands of servers in size. ObjectGrid is part of WebSphere Extended Deployment edition but can be used with older versions of WebSphere as well as competitive application servers such as WebLogic?, JBoss, Tomcat or just J2SE.
It provides a JCACHE Map collection style API as well as a POJO style API that allows the application to persist object graphs easily to the cache using Java 5 annotations. All data in the grid can be indexed and queried. ObjectGrid has a continuous query engine that allows realtime queries to be executed and updated in real time as transactions commit data. ObjectGrid has a DataGrid? API which allows distributed Map and reduce operations against a grid.
