Re: Criteria for upgrading to 3.x releases in PROD

2016-04-24 Thread Jack Krupansky
The old "most stable" labeling was super-important in the old days since newer releases tended to have a fair amount of instability - hence the admonition to wait for a x.y.5 release before using the x.y release line. But that dramatic degree of release instability is no longer the case. Besides, w

Jack, The question was about publishing "most stable" release on Apache website as it done before 3.x. Regarding your comments, I still feel adventure cant happen in production systems. And you should certainly test every release before upgrading but you woulf not like to upgrade to latest relea

Is the question whether a new application can go into production with 3.x, or whether an existing application in production with 2.x.y should be upgraded to 3.x? For the latter, a "If it ain't broke, don't fix it" philosophy is best. And if there are critical bug fixes needed, simply upgrade the 2

Jonathan, I understand you point. In my perspective, people in production usually prefer stability over features and would always want at least emergency fix releases if not fully supported versions.I am glad that today we have such releases which are very stable and not yet EOL. Its just that u

Anuj, The problem is that this question defies a simplistic answer like "version X is the most stable" (are you willing to use unsupported releases? what about emergency-fix-only? what features can you not live without?) so we're intentionally resisting the urge to oversimplify the situation. O

Hi All, Let me reiterate, my question is not about selecting right Cassandra for me.  The intent is to get dev community response on below question.

This is best for the users list. Test the releases yourself and then decide when it's ready for your use case, ops team, and organization. This is a personal decision and not one for *thousands* of others on this mailing list to make for you. best, kjellman > On Apr 18, 2016, at 10:54 AM, Anuj

Hi All, For last several months, the "most stable version" question pops up on the user mailing list and then people get all sorts of responses/suggestions.. If you are conservative go for x if adventurous y.. If you have good risk appetite go for x else y.. If you want features go for x else y..

The answer will depend on how conservative you are. The most conservative choice overall would be to go with the 2.2.x line. 3.0.x if you want to the new nice and shiny 3.0 things, but can tolerate some risk (the branch has a lot of relatively new core code, and hasn’t yet been tried out by as

As an operator, I’d imagine it’s mostly the same as always - stability will vary by workload, so test with your workload until you’re confident. If x.y.Z where Z >= 6 was basically the guideline most people used before, then it’s probably worth considering 3.5 and 3.7 as worth testing in your sp

Hi, Tick-Tock release strategy in 3.x was a good intiative to ensure frequent & stable releases. While odd releases are supposed to get all the bug fixes and should be most stable, many people like me, who got used to the comforting "production ready/stable" tag on Apache website,  are still rel
