Operational Database clusters
The Operational Database (OpDB) template is removed from the Cloudera Data Hub. You can access the Cloudera Operational Database instead as a superior product.
The Cloudera Operational Database is a NoSQL database powered by Apache HBase designed to support custom OLTP applications that want to leverage the power of BigData. Apache HBase is a NoSQL, scale-out database that can easily scale to petabytes and stores tables with millions of columns and billions of rows.
Cloudera Operational Database also contains Apache Phoenix which provides a way to use HBase through an SQL interface.
Cloudera recommends you to use the Cloudera Operational Database to create Operational Database clusters.
