How does Cassandra handle failures and node failures?

Cassandra uses a partition tolerance architecture to handle faults and node failures. When a node fails or experiences a fault, Cassandra automatically redistributes the data from the failed node to other nodes to ensure data availability and consistency. If a node completely fails, Cassandra uses replication strategies to ensure data redundancy backup, thus preventing data loss.

Furthermore, Cassandra also features automatic fault detection and self-healing capabilities, which can promptly identify node failures and take actions to rectify the issue. Administrators can also manually perform node repair and fault transfer operations to address malfunctions and node failures.

In general, Cassandra has strong fault-tolerance capabilities, effectively handling failures and node losses, ensuring data availability and consistency.
