Sun Nov 20 01:14:33 2016  arijit91:Hello all, I understand that using "nodetool removenode" can violate quorum consistency because we stream replicas from a node at random for each key. Is my understanding correct that we can still maintain quorum consistency by streaming the replica with the most recent timestamp during removenode, and that this will dispense with the need to run a repair after a removenode operation?

Sun Nov 20 03:53:07 2016  jeffj:arijit91: how do you propose streaming the replica with the most recent timestamp?
Sun Nov 20 03:53:25 2016  jeffj:doing so sounds a lot like a repair
Sun Nov 20 04:02:05 2016  arijit91:jeffj: Yes, basically a repair during removenode and not after. Since this is a rare scenario, the extra cost is not as important as the consistency guarantee?
Sun Nov 20 04:06:38 2016  jeffj:counterpoint: i'd rather get a third replica alive as soon as possible. if you just want to do one operation, assassinate+repair
Sun Nov 20 04:07:06 2016  jeffj:i'm just one person, feel free to jira it up and propose it (or discuss it on dev@ , probably more likely to get eyeballs there than irc @ 8pm on a saturday night)
Sun Nov 20 04:07:19 2016  jeffj:just seems like a lot of work with little upside to me
Sun Nov 20 04:08:22 2016  arijit91:I see, thanks for the perspective. I imagined the change would just be a few lines, but apparently not - haven't read the source in too much detail
