2DC Support with Cross-Cluster Replication

CockroachDB, a distributed SQL database designed for resilience and scalability, has introduced two cross-cluster replication tools - physical cluster replication (PCR) and logical data replication (LDR). These tools address the challenges faced by users with limited access to multiple data centers or high latency requirements. PCR enables an active-passive architecture for disaster recovery, while LDR supports an active-active architecture for high availability. Both tools maintain CockroachDB's resiliency, scalability, and strong consistency within their respective clusters.
