Subject [jira] [Commented] (HBASE-12476) HydraBase Consensus Protocol

stack commented on HBASE-12476:
-------------------------------

Thanks for putting the code into a module (thanks also for posting)

What direction do you think we should take this contrib?  Toward the layout described in the
hydrabase doc or are you thinking we'd recast it as an in-cluster quorum-of-regions?  If the
latter, would it be on all the time -- a different sort of hbase -- or would it be something
you could enable?  HBase 2.0 or HBase 1.0?

Sorry for the big questions.  No need of an answer now.... but we need to all chat.

What should we do about swift out here in apache hbase?  We'd redo it as pb and rpc calls?

airlift is not for REST services, right? You are just using it for stats?  You like it? Better
than the histograms we have going on out herein apache hbase?  You have a Counter, Duration,
TimeDistribution, and ExpotentialDecay.. Need airlift for this or could redo doing our current
metrics dependencies?

Should apache hbase make use of jmxutils too? How you folks using it (Not reviewed the patch
yet).

Let me get you more feedback. Above are first impression.  Thanks.
