Elliott Clark created HBASE-12259:
-------------------------------------
Summary: Bring quorum based write ahead log into HBase
Key: HBASE-12259
URL: https://issues.apache.org/jira/browse/HBASE-12259
Project: HBase
Issue Type: Bug
Affects Versions: 2.0.0
Reporter: Elliott Clark
HydraBase (
https://code.facebook.com/posts/321111638043166/hydrabase-the-evolution-of-hbase-facebook/
) Facebook's implementation of HBase with Raft for consensus will be going
open source shortly. We should pull in the parts of that fb-0.89 based
implementation, and offer it as a feature in whatever next major release is
next up. Right now the Hydrabase code base isn't ready to be released into the
wild; it should be ready soon ( for some definition of soon).
Since Hydrabase is based upon 0.89 most of the code is not directly applicable.
So lots of work will probably need to be done in a feature branch before a
merge vote.
Is there anything clean up that needs to be done before the log implementation
is able to be replaced like this?
What's our story with upgrading to this? Are we ok with requiring down time ?
