Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

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.
