Summary

CockroachDB v23.2 introduces physical cluster replication (PCR), a feature designed to enhance disaster prevention by replicating data asynchronously at the byte level across two clusters, thus ensuring business continuity without the latency issues associated with cross-region writes. This update addresses limitations faced by enterprises with legacy failover strategies limited to two regions, unlocking the full resilience features of CockroachDB. PCR provides an automated and flexible solution allowing for multiple standby clusters and cloud configurations, offering a more efficient alternative to traditional backup and restore models by maintaining constantly updated replicas, thereby lowering recovery point objectives (RPO) and recovery time objectives (RTO). The feature, currently in preview and requiring an enterprise license, is part of a broader shift towards disaster prevention over recovery, aiming to maintain application availability even amid regional outages.
