Good questions, Enis. If my bandwidth permits, I am planning to collect performance statistics using ycsb against cluster with and without MOB feature enabled. Cheers On Thu, Mar 3, 2016 at 3:49 PM, Enis Söztutar wrote: > Regardless of the backport, did we do the same regression analysis for t

Regardless of the backport, did we do the same regression analysis for the master branch merge at the time of the merge? Like make sure that the latencies and stability of non-mob is affected or not. Sorry, I was not following the merge vote closely. The reason I am asking is that although we can

Just to be clear, I did not actually oppose a backport of MOB. Although - I have to say am sympathetic to Elliott's position that there's a project management reason not to. My insistence here is "merely" for this change in particular a backport to the branch we are making production releases from

In the middle of writing response to this thread, I saw subsequent comments from Andrew, Jon and Elliott. In light of opposition from the community w.r.t. backporting MOB feature, I think it suffices to say that this wouldn't be done now. Thanks everyone for chiming in. On Thu, Mar 3, 2016 at 2:

I just don't see a why we would back port. We're going to release a 2.0 when things are ready. It will be a major feature release. MOB is a major feature. Without compelling reason backporting to branch-1 seems like an end run around what sem ver is supposed to mean (not the api guarantees, the act

In addition to Stack's points those of us running HBase in production will need assurance in the form of data collected from a plausible test environment that the MOB backport does not affect function, stability, or performance for anyone who doesn't want it. Furthermore some affirmative demonst
