Re: CASSANDRA-9472 Reintroduce off heap memtables - patch to 3.0

2017-07-31 Thread Jon Haddad 
+1.  IMO there’s very little reason to use 3.0 at this point.  If someone wants 
to back port and make a 3.0 patch publicly available, cool, but merging it into 
3.0 after 2 years doesn’t make much sense to me.

+1.  The feature is there in 3.11.x if you are running one of the use cases 
where this helps, and for most existing things 3.0 and 3.11 are about the same 
stability, so you can go to 3.11.x if you want to keep using the off heap stuff.

Personally / individually, I'd much rather see 3.0 stabilize.
