Hi, There is a nice fellow project named as Apache Ignite. It is described as:
*Apache Ignite In-Memory Data Fabric is a high-performant, integrated and distributed in-memory platform for computing and transacting on large-scale data sets in real-time, orders of magnitude faster than possible with traditional disk-based or flash-based technologies.* It has a feature: *Hadoop Accelerator ships with alternate high-performance implementation of job tracker which replaces standard Hadoop MapReduce* and described at here: https://apacheignite.readme.io/v1.3/docs/map-reduce I wanted to arouse your interest due to we may want to integrate it to Apache Gora. (Of course we should make some performance tests). Kind Regards, Furkan KAMACI
