OpDB powered by Apache Accumulo overview
Apache AccumuloTM is an ideal solution for government agencies looking for a secure, distributed NoSQL data store to serve their most performance-intensive Big Data applications. The Operational Database powered by Apache Accumulo (OpDB) service is the Cloudera package of Apache Accumulo.
Apache AccumuloTM is an open source project integrated with Hadoop that provides the ability to store data in massive tables (billions of rows / millions of columns) for fast and random access. Accumulo was created and contributed to the Apache Software Foundation by the National Security Agency (NSA). It has quickly gained adoption as a Hadoop-based key/value store for applications that have unique and stringent information security requirements.
