Apache Accumulo Description
Apache Accumulo allows users to store and manage large data sets across a cluster. Accumulo uses Apache Hadoop HDFS to store its data, and Apache ZooKeeper to reach consensus. Accumulo is used by many users, but there are also open-source projects that use it as their underlying store. Take the Accumulo tour to learn more, and then run the Accumulo sample code. If you have any questions, please don't hesitate to contact us. Accumulo offers a programming mechanism called Iterators that allows you to modify key/value pair at different points in the data management process. Each Accumulo key/value pair is assigned a security label that limits the query results based on user authorizations. Accumulo can be run on a cluster that uses one or more HDFS instances. As Accumulo's data grows, nodes can be added and removed.
