Cassandra 2.2.5 / 3.9 Installation/Configuration Guide

Apache Cassandra is an open source, eventually consistent, distributed database system used by Orchestration Server to store customer session information. It is designed to be highly scalable and decentralized (such that there is no single point of failure).

• This guide describes working with a Cassandra 2.2.5 installation (supported as of ORS Release 8.1.400.40 on 03/31/16), and a Cassandra 3.9 installation (supported as of ORS Release 8.1.400.51 on 01/12/17).
• For information on working with Cassandra versions prior to 2.2.5, see the Cassandra 1.1.x Installation/Configuration Guide on the Orchestration Server documentation website.

Important

Cassandra connectivity is recommended for Orchestration Server deployments. Orchestration Server will execute without Cassandra, but session recovery and session http redirects will not be available without connectivity to at least one configured Cassandra node.
