Doradus OLAP is an open source storage and query service that leverages the Cassandra NoSQL database for persistence. Borrowing techniques from online analytical processing, columnar storage, and sharding, Doradus OLAP yields extremely compact databases and can search millions of records per second without indexes. Many analytics applications can host all data on a single node, but the Cassandra underpinning allows linear scalability, replication, and fault tolerance when needed.

This webcast will introduce Doradus OLAP and cover these topics:

  • How Doradus OLAP extends Cassandra from the "outside"
  • Techniques used for achieving extreme compression
  • The Doradus data model including its support for bi-directional relationships
  • Examples of the REST API and Lucene-based Doradus Query Language (DQL) for simple queries, searching relationship graphs, and complex analytic queries
  • An example time-series application that stores one billion objects in less than 2GB
