Re: Supporting multiple JDKs

Apache Cassandra does not distribute JDK1.7 built releases.

The only way a user could repeat such a bug is if they have built C* themselves.

I don't think the project should be responsible for every possible build 
combination tom, dick and harry can do.
That's my 2cents anyway. 

And I would suggest to go further and crash the build with JDK1.7 so we can 
take away the possibility for users to shoot their foot off this way.

I referred to dtests, how would you do this on CircleCI?
Today dtests take 5-9 hours on builds.apache.org, not including re-runs for 
offheap, large, novnode.

Currently I'm unclear on how we would make a stable release using only JDK8, 
maybe their are plans on the table i don't know about?
 
The current build.xml requires both JDKs to run `ant artifacts`.
That is any release will have compiled in ant all but one class with 
`_build_multi_java` instead of `_build_java8_only`.

I'm not familiar with optional jobs or workflows in CircleCi, do you have an 
example of what you mean at hand?
I like the idea of having a collection of CircleCi workflows, even if I'd 
rather see less JDKs supported at compile-time.

Off-topic, but what are your thoughts on this? Can we add `ant artifacts`, and 
the building of the docs, as a separate jobs into the existing default CircleCI 
workflow? I think we should also be looking into getting 
https://cassandra.apache.org/doc/latest/ automatically updated after each 
successful trunk build, and have https://cassandra.apache.org/doc/X.Y versions 
on the docs in place (which are only updated after each patch release).

Another thing to  discuss will be how to improve testing further from the
learning of finding bugs in C* 4.0.

Re: NGCC 2018?

[Jason Brown]

+1 to Jon's sentiment. Further, perhaps we should use that time after
GA'ing 4.0 to poll our users what they need/want from the next major
release of the database.

Re: NGCC 2018?

[Jonathan Haddad]

I'm thinking a month or two after 4.0 would give us time to unwind after
the release and start to give real thought to big changes coming in the
next release.  Let's focus on one thing at a time.
