Cassandra extension classes

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

The CMDB CI Class Models app adds class models that extend the CMDB class hierarchy, including 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 CMDB CI Class Models release notes.

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
