Overview

Kundera is a "Polyglot Object Mapper" with a JPA interface. The idea behind Kundera is to make working with NoSQL Databases drop-dead simple and fun. Kundera is being developed with following objectives:

  • To make working with NoSQL as simple as working with SQL
  • To serve as JPA Compliant mapping solution for NoSQL Datastores.
  • To help developers, forget the complexity of NoSQL stores and focus on Domain Model.
  • To make switching across data-stores as easy as changing a configuration.

Supported Datastores

Kundera currently supports following data stores :

  • Cassandra
  • MongoDB
  • HBase
  • Redis
  • OracleNoSQL
  • Neo4j
  • Couchdb
  • Relational databases

You can find the list of data stores(specific versions) supported by Kundera [here] (https://github.com/impetus-opensource/Kundera/wiki/Datastores-Supported).
