Wed Jan 18 13:02:47 2017  jasobrown:are new features (minor optimizations) still going into 3.X, or is it only 4.0 from now?
Wed Jan 18 13:03:02 2017  jasobrown:i'm thinking 4.0 only ...

Wed Jan 18 14:32:08 2017  iamaleksey:trunk only
Wed Jan 18 14:43:12 2017  jasobrown:iamaleksey: sgtm, thx!
Wed Jan 18 14:51:21 2017  jasobrown:for bug fixes, are we skipping 3.X now, and just 3.0->3.11->trunk?
Wed Jan 18 14:54:56 2017  iksaif:jasobrown: do we have tests for compatibility between 3.9 and 3.x ? (both version running at the same time ?)
Wed Jan 18 14:55:35 2017  iksaif:(I know there is an upgrade test, but I'm not sure what it doesexactly)
Wed Jan 18 14:55:35 2017  jasobrown:iksaif: hmm, if we do, it would be in the dtests (upgrade tests)
Wed Jan 18 14:56:20 2017  jasobrown:i haven't been inside the upgrade_tests dtest myself, so i don't have a great answer unfortunately
Wed Jan 18 14:56:46 2017  iksaif:asking because last time I rebased on 3.X I ended up with corrupted sstables and a lot of weird messages in the logs .. but hopefully if it's a real issue it will be caught by the tests (unfortunately I don't have time this week to reproduce it)
Wed Jan 18 14:56:48 2017  jasobrown:although i'm supposed to dive into it at *some* point in the near future
Wed Jan 18 14:58:28 2017  jasobrown:yeah, that doesn't sound right. was that just happening locally, or did you actually deploy that?
Wed Jan 18 14:59:59 2017  iksaif:I actually deploy that in a test env
Wed Jan 18 15:00:16 2017  iksaif:then I rolled back, removed the corrupted files
Wed Jan 18 15:00:28 2017  iksaif:in a non-version-mixed env everything worked fine
Wed Jan 18 15:00:34 2017  iksaif:I'll try to reproduce it tomorrow
Wed Jan 18 15:01:01 2017  jasobrown:funky
Wed Jan 18 15:01:20 2017  jasobrown:yeah, ping the channel with any more update tmw when you can
Wed Jan 18 15:02:29 2017  jasobrown:iamaleksey: thanks for rounding up that 3.X email thread :)

Wed Jan 18 16:46:29 2017  iksaif:(in this case 3.9 is also reading sstables generated by 3.X)

Wed Jan 18 22:50:23 2017  thobbs:aweisberg: it's probably better just to stick with tuples
Wed Jan 18 23:03:44 2017  mstepura:Joined the channel
Wed Jan 18 23:12:31 2017  iamaleksey:it's doable now, in 3.0 and upwards
Wed Jan 18 23:12:47 2017  iamaleksey:but better stick with tuples
