Common replication topologies

You must learn about the common replication topologies before you configure and deploy HBase replication.

Some common replication topologies are:
  • A central source cluster might propagate changes to multiple destination clusters, for failover or due to geographic distribution.
  • A source cluster might push changes to a destination cluster, which might also push its own changes back to the original cluster.
  • Many different low-latency clusters might push changes to one centralized cluster for backup or resource-intensive data-analytics jobs. The processed data might then be replicated back to the low-latency clusters.
  • Multiple levels of replication can be chained together to suit your needs. The following diagram shows a hypothetical scenario. Use the arrows to follow the data paths.
