All the major linux vendors are supporting JDK8 LTS (like 2024+ or something) if I'm not mistaken, so I don't think there's a burning *need* to push for JDK11 support specifically in 4.0. To Mick's point, no reason why project folks that want JDK11 officially supported can't get started working on validating it now and we give it our blessing in whatever C* patch rel we've validated it on right?
If most folks are testing with 11 at this point, How do we get this data? I think most of the DS folks are testing on JDK8 since that's the one we as a project have been signalling as officially supported for 4.0. Anyone else have another PoV and been doing testing on JDK11 instead? Are there features JDK11 brings to the table (improvements in GC, etc) that are compelling that increase the urgency of pushing for this? Isn't our official CI all JDK8? https://builds.apache.org/view/A-D/view/Cassandra/ On Mon, Jul 13, 2020 at 3:26 PM Elliott Sims <elli...@backblaze.com> wrote: > Personally, I'd planned to upgrade to 4.0 on JDK8 but only wait a few weeks > before starting to update to JDK11 afterwards.
