Apache Accumulo (accumulo)
Category: big-data
Programming language: Java
The Apache Accumulo sorted, distributed key/value store is
      based on Google's BigTable design. It is built on top of Apache Hadoop,
      Apache Zookeeper, and Apache Thrift. It features a few novel improvements
      on the BigTable design in the form of cell-level access labels and a
      server-side programming mechanism that can modify key/value pairs at
      various points in the data management process.
