Gridgain

GridGain enables organizations to accelerate data processing in their Hadoop deployments by providing an in-memory platform. The platform can be used as a database, a stream computing platform, a messaging platform or an accelrator for hadoop based computations. GridGain's in-memory file system accelerates I/O in the Hadoop stack. GridGain requires zero code change to existing MapReduce code for similar performance improvement. It also offers a management and monitoring tool called GridGain Visor for its Hadoop accelerator platform. It is built on top of Apache Ignite, an In-Memory data Fabric. Its clients include Apple, Avis, Canon, IHG, McGraw-Hill Education, Moody's KMV, Sberbank, Sony, TomTom, and Worldpay. The company was named a 'Cool Vendor' for In-Memory Computing Technologies by Gartner in 2014. Gridgain has incubated and open sourced the In-Memory platform in Apache as Ignite.
