ClickHouse Cross-Datacenter Replication: A Technical Deep Dive
ClickHouse supports cross-datacenter replication via its ReplicatedMergeTree engine and ClickHouse Keeper coordination service. The architecture replicates only new data parts across nodes, minimizing network traffic while ensuring high availability. This setup enables fault tolerance, read scalability, and zero-downtime maintenance for distributed analytical workloads.
