Sorry, I misread your earlier email. Yes, there are drivers that do mixed protocol versions. Not sure if the 4.0 java driver does, but at least one previous version did. > On Sep 24, 2019, at 7:19 PM, Blake Eggleston > wrote: > > Yes, but if a client is connected to 2 different n

Re: fixing paging state for 4.0

Changing paging state format is kind of a pain since the driver treats it as an opaque blob. I'd prefer we went with Sylvain's suggestion to just interpret Integer.MAX_VALUE as "no limit", which would be a lot simpler to implement. > On Sep 24, 2019, at 10:44 AM, Jon Haddad wrote: > > I'm work

Time for a new 3.0/3.11 release?

Hi dev@, Any objections to doing a new 3.0 and 3.11 release? Both branches have accumulated a decent number of changes since their last release, the highlights being improved merkle tree footprint, a gossip race, and a handful of 2.1 -> 3.x upgrade bugs. Thanks, Blake --

Re: Stabilising Internode Messaging in 4.0

It seems like one of the main points of contention isn’t so much the the content of the patch, but more about the amount of review this patch has/will receive relative to its perceived risk. If it’s the latter, then I think it would be more effective to explain why that’s the case, and what leve

Re: Both Java 8 and Java 11 required for producing a tarball

You may want to wait until CASSANDRA-14607 is finished before starting on 14712. I think it will end up unwinding most of the stuff requiring building with dual jdks (either as part of that ticket or an immediate follow on). I'm still working on making sure I haven't broken anything, but I'm cur
