Cassandra extension classes

The CMDB CI Class Models app adds or updates classes for Cassandra databases.

CMDB CI Class Models is a ServiceNow Store app that adds class models that extend the CMDB class hierarchy. The new or updated classes include class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

See the release notes for all CMDB CI class models.

Cassandra

Cassandra is a distributed database that is treated as one database and that runs on a cluster of Linux nodes. A Cassandra cluster CI represents a logical entity that doesn’t refer to a Linux node.

Classes

This section lists the classes that the CMDB CI Class Models app adds or updates. For the list of classes in the base system, including classes that this app might extend, see CMDB tables descriptions.
