Now, researchers at Yale University have created a database-Hadoop hybrid that they say offers the best of both worlds: fast performance and the ability to scale out near-infinitely. HadoopDB was built using PostGreSQL (though MySQL has also successfully been swapped in), Hadoop and Facebook's Hive implementation, according to Daniel Abadi, Yale computer science professor, whose students built this prototype."
