"Apache Accumulo is based on the design of Google's BigTable and is powered by Apache Hadoop, Apache Zookeeper, and Apache Thrift. Accumulo has several novel features such as cell-based access control and a server-side programming mechanism that can modify key/value pairs at various points in the data management process."
-- Splunk marketing VP Sanjay Mehta spoke to Dr. Dobb's Journal to say, "Streaming resource libraries enable developers to connect Hunk to NoSQL and other data stores, such as Apache Accumulo, Apache Cassandra, Couchbase, MongoDB, and Neo4j, for data exploration, analysis, and visualization in Hunk. All without fixed schemas or moving data to a separate in-memory store."
Please keep in mind that Splunk Analytics for Hadoop was called Hunk until this week ; - )
