Cluster in this context is a typical data center deployment: HDFS + ZK + HBase master(s) + HBase regionservers. > Typically with MySQL one would have 1 master (for writes) > and N slave servers (for reads). Is this a similar use case for > HBase replication? I think you are thinking more along the lines of HBASE-2357: https://issues.apache.org/jira/browse/HBASE-2357 (Hmm... I forgot I took on this issue...) What I'm talking about is HBASE-1295, or http://hbase.apache.org/replication.html . What I personally would use 0.92 replication for is: - To deploy a service in multiple geographies and sync global state (eventually); but within the geography take advantage of HBase's consistency properties - To stream a subset of important data to a small reserve cluster for disaster recovery - Andy
