Agree with what Ian says below except I'd say with work it's possible to do
cross DC quorum writes in a layer on top of HBase that persists into
HBase, like
when Google built Megastore on BigTable. At this year's VLDB if I recall
correctly there was a megastore-like system with an interesting varia

Yes, I think so. A single HBase cluster can't (or, at least, really shouldn'
Thanks Ian. I DID miss the point. The person who started the chain is a

What failure condition are you trying to safeguard against? A full
data center failure? That's when you would lose your entire cluster
and need the DR to kick in. Otherwise, you could deploy such that an
entire rack failure or even a row failure won't take you down. Just

Juan,
No; that would mean every single write to HBase has to wait for an ACK from a
remote data center, which would decrease your cluster throughput dramatically.
If you need that, consider other database solutions.

I was reading up on HBase Replication and wanted to make sure I'm not
missing something.
Given that replication happens asynchronously the replication strategy has
an "eventually consistent" policy.
I was considering using this feature for Production / Disaster Recovery
setup.
Is there a way to
