Description: The system keyspace in Cassandra is a fundamental component that stores metadata about the cluster. This keyspace, known as ‘system’, contains critical information that allows Cassandra to manage and operate efficiently. It includes data about the cluster’s configuration, such as the structure of tables, indexes, functions, and data types. Additionally, the system keyspace is responsible for maintaining information about the nodes in the cluster, their status, and performance, which is essential for data replication and distribution. Cassandra’s architecture, designed to be highly scalable and fault-tolerant, relies on this keyspace to ensure that read and write operations are performed effectively. Cassandra’s ability to handle large volumes of data in distributed environments is facilitated by the organization and access to the information contained in the system keyspace. In summary, this keyspace is not only a repository of metadata but also plays a crucial role in the daily operations and overall health of the Cassandra cluster.
