[jira] Created: (HBASE-1160) Multi-site replication support
Multi-site replication support
------------------------------
Key: HBASE-1160
URL: https://issues.apache.org/jira/browse/HBASE-1160
Project: Hadoop HBase
Issue Type: New Feature
Reporter: Jean-Daniel Cryans
HBase should support multi-site replication in order to provide higher availability. A first version with eventual consistency could be easy to implement.

bq. I don't think we need a statistical 'eventual consistency' multi-write (Eg: paxos), but instead a straight forward replication stream (a la redo log replication from Oracle, mysql, etc) would be pretty good. Tools to monitor that replication stream (replicas are X seconds behind kind of thing) would also be necessary.
Thanks for your input. I was also thinking that something like MySQL replication would be good enough for a majority of people at this point.

------------------------------------
We'd probably want to avoid spanning a cluster across datacenter boundaries... it's too easy to get into irreconcilable network splits.
Replication as a site-to-site backup is a great approach. Multi-master replication would allow concurrent read/write when the link between the sites is down, but the internet connection is still available (very common scenario surprisingly).

Sorry, I opened HBASE-1295 because I had forgotten about this issue. Close this issue in favor of 1295? Or vice versa?
