Thanks Jonathan and Julien for the advice. I will go with 3.0.

Cheers

Re: Cassandra stable version for production

[Julien Anguenot]

Yes, we have been running 3.0.x for a while and we consider it mostly stable 
now.  Though, we did not have to bootstrap new nodes / new DCs since running 
3.0.x so I cannot speak about that part.

In addition, DSE 5 is now running off 3.0.x which will definitely bring a lot 
of bug fixes from Datastax production customers.

The only real issue we, and others, experienced while migrating to 3.0.x, is 
that one: 
   
   https://issues.apache.org/jira/browse/CASSANDRA-11887 


Tyler seems to think this issue might be related to that one that got fixed in 
upcoming 3.0.9:

   https://issues.apache.org/jira/browse/CASSANDRA-12144 


I agree with Jon about not putting Tick Tock release in production as it would 
definitely require some major involvements to test and report issues every 
month. I know I would not do it unless working on some non production projects 
that would require bleeding edge features.

Although, the tick tock release has advantages regarding new feature 
availability and new feature short term stability I still believe a long term 
stable branch like 3.0.x is necessary for most users. 

IMHO, considering the amount of questions asking what Cassandra version is 
ready for production, that long term stable release should be the one listed as 
stable on http://cassandra.apache.org/  to avoid 
confusion.

Personally hoping both release models (tick tock and long term stable release) 
will still co-exist after September.

Re: Cassandra stable version for production

[Jonathan Haddad]

If I were starting a new project today, I'd go with 3.0.  It's gotten over
half a year of bug fixes.

I personally would have a hard time putting a tick tock release into
production, as you're either getting new features or putting a version in
which won't receive any further bug fixes, so unless you're ready to dive
into code or backport patches (or upgrade every month thereafter to get
bugfixes in addition to new features) 3.0 is probably your best bet.
