We have three new Hibernate Projects, this projects add great possibility.
This is a framework that is designed for horizontal partitioning. It’s key features are that Shards allows you still use Hibernate API, You can add your own shredding strategies and of course it’s open source.
This helps you achieve full text search. It’s use in background Apache Lucene. And make dirty work for us (sync, manage indexes etc.
This allows to keep in one place our constraint about model. With annotation we can specify constraint, and hibernate will build and apply validation rules for us in many places (database schema, inserts/updates etc.)
