Apache Accumulo is a sorted, distributed key/value store. It is a robust, highly scalable, high performance data storage and retrieval system.
Apache Accumulo is based on Google’s BigTable design and is built on top of Apache Hadoop, Zookeeper, and Thrift. Apache Accumulo features a few novel improvements on the BigTable design in the form of cell-based access control and a server-side programming mechanism that can modify key/value pairs at various points in the data management process.
Accumulo operates over the Hadoop Distributed File System (HDFS), which is part of the popular Apache Hadoop project. Accumulo features automatic load-balancing and partitioning, data compression and fine-grained security labels. It has cell-level access labels and a server-side programming mechanisms.
