Subject Kundera 2.2 released
Date Thu, 08 Nov 2012 18:21:06 GMT
Hi All,

We are happy to announce release of Kundera 2.2.

Kundera is a JPA 2.0 based, object-datastore mapping library for NoSQL datastores. The idea
behind Kundera is to make working with NoSQL Databases
drop-dead simple and fun. It currently supports Cassandra, HBase, MongoDB and relational databases.

Major Changes in this release:
* Geospatial Persistence and Queries for MongoDB
* Composite keys support for Cassandra and MongoDB
* Cassandra 1.1.6 migration
* Support for enum data type
* Named and Native queries support for REST based access

Github Issues Fixes (
Issue 136 - JPQL queries without WHERE clause or parameters fail
Issue 135 - MongoDB: enable WriteConcern, Safe mode and other properties on operation level.
Issue 133 - Externalize the database connection configuration
Issue 132 - problem in loading entity metadata when giving class name in class tag of persistence.xml
Issue 130 - Row not fully deleted from cassandra on em.remove(obj) - then cannot reinsert
row with same key

We have revamped our wiki, so you might want to have a look at it here:
