The Cassandra database was introduced in 6.1 to replace the Global xDB database. Apache Cassandra is a highly scalable, high-performance, distributed database. It is designed to handle large amounts of structured data across many nodes. It provides HA with no single point of failure. Cassandra is highly scalable, as it allows us to add more vRealize Operations nodes in the future to the existing cluster.
Currently, the database stores the following:
- User preferences and configuration
- Alerts definition
- Customizations
- Dashboards, policies, views
- Reports, licensing
- Shard maps
- Activities
Cassandra stores all the info that we see in the CONTENT folder; basically any settings that are applied globally.
