What are the replication strategies available in Cassandra?

There are several replication strategies available in Cassandra.

SimpleStrategy: Under this strategy, data is replicated to a specified number of replicas. This strategy is suitable for single data center

deployments.

Network Topology Strategy: This approach allows for flexible specification of the number of replicas in each data center based on the topology structure. It is suitable for multi-data center deployments.

  1. Data center strategy (DatacenterShardAwareStrategy): This strategy dynamically adjusts the number of data replication copies based on the load of the data center to achieve load balancing.
  2. Customize strategy: Users can write their own custom replication strategies to achieve more flexible control over data replication.
