Tungsten Fabric database¶
Tungsten Fabric (TF) uses Cassandra and ZooKeeper to store its data. Cassandra is a fault-tolerant and horizontally scalable database that provides persistent storage of configuration and analytics data. ZooKeeper is used by TF for allocation of unique object identifiers and transactions implementation.
To prevent data loss, Mirantis recommends that you simultaneously back up the ZooKeeper database dedicated to configuration services and the Cassandra database.
The backup of database must be consistent across all systems because the state of the Tungsten Fabric databases is associated with other system databases, such as OpenStack databases.
