Hibernate Shards, a framework that adds support for horizontal partitioning

You can't always put all your relational data in a single relational database. Sometimes you simply have too much data. Sometimes you have a distributed deployment architecture. Sometimes the lawyers say "no" (or more likely, "NOOO!"). Whatever your reasons, talking to multiple relational databases inevitably complicates the development of your application. Hibernate Shards is a framework that is designed to encapsulate and minimize this complexity by adding support for horizontal partitioning to Hibernate Core.Despre horizontal partitioning aici: http://en.wikipedia.org/wiki/Partition_%28database%29Articol: http://google-code-updates.blogspot.com/2007/03/ode-to-hibernate.htmlWebsite proiect: http://shards.hibernate.org/
