Deploying Cassandra across Multiple Data Centers
Cassandra is a distributed system designed for deployment across multiple data centers. Key features include Replication Factor, Replica Placement Strategy (NetworkTopologyStrategy), Snitch, and Consistency Level (LOCAL_QUORUM and EACH_QUORUM). These components can be configured to optimize geographical distribution, redundancy, failover, disaster recovery, or analytics. An example configuration for two data centers includes NetworkTopologyStrategy with a Replication Factor of 3 in each data center, RackInferringSnitch, and LOCAL_QUORUM as the consistency level for both reads and writes. This setup minimizes network latency while maintaining reasonable data consistency.
