Which replication strategies are supported by Cassandra?

Cassandra supports several replication strategies, including:

1. SimpleStrategy: A simple replication strategy designed for use in a single data center environment.
2. NetworkTopologyStrategy replicates data based on the topology structure of data centers, allowing for flexible configuration of the number of replicas in different data centers.
3. OldNetworkTopologyStrategy is the outdated version of NetworkTopologyStrategy and is not recommended for use.
4. LocalStrategy: A replication strategy that is suitable for copying data only within a local data center.
5. SimpleStrategy and NetworkTopologyStrategy are the most commonly used replication strategies. SimpleStrategy is suitable for a single data center environment, whereas NetworkTopologyStrategy is suitable for a multi-data center environment. By selecting the appropriate replication strategy, data replication and replica settings can be tailored according to application needs.
