Cloudera Operational Database is powered by Apache HBase and Apache Phoenix. Apache HBase is a column-oriented NoSQL database management system that runs on top of the Hadoop Distributed File System (HDFS), a main component of Apache Hadoop. It enables random, strictly consistent, and real-time access to petabytes of data. Apache Phoenix enables OLTP and operational analytics in Hadoop for low latency applications by combining the best of both worlds:
- The power of standard SQL and JDBC APIs with full ACID transaction capabilities.
- The flexibility of late-bound, schema-on-read capabilities from the NoSQL world by leveraging HBase as its backing store.
Apache Phoenix provides a SQL interface for managing data in Apache HBase. Operational Database powered by Apache Accumulo is the Cloudera package of Apache Accumulo.
