I would appreciate if you guys share your thoughts on the concerns I expressed 
regarding Cassandra End of Life policy. I think these concerns are quite 
genuine and should be openly discussed so that EOL is more predictable and 
generates less overhead for the users.
I would like to understand how various users are dealing with the situation. 
Are you upgrading Cassandra every 3-6 mths? How do you cut short your 
planning,test and release cycles for Cassandra upgrades in your 
application/products?



ThanksAnuj

Hi,
As per my understanding, a Cassandra version n is implicitly declared EOL when 
two major versions are released after the version n i.e. when version n + 2 is 
released.
I think the EOL policy must be revisted in interest of the expanding Cassandra 
user base. 
Concerns with current EOL Policy:
In March 2015, Apache web site mentioned that 2.0.14 is the most stable version 
of the Cassandra recommended for Production. So, one would push its clients to 
upgrade to 2.0.14 in Mar 2015. It takes months to roll out a Cassandra upgrade 
to all your clients and by the time all your clients get the upgrade, the 
version is declared EOL with the release of 2.2 in Aug 2015 (within 6 mths of 
being declared production ready). I completely understand that supporting 
multiple versions is tougher but at the same time it is very painful and 
somewhat unrealistic for users to push Cassandra upgrades to all thier clients 
after every few months.
One proposed solution could be to declare a version n as EOL one year after n+1 
was declared Production Ready. E.g. if 2.1.7 is the first production ready 
release of 2.1 which is released in Jun 2015, I would declare 2.0 EOL in Jun 
2016. This gives reasonable time for users to plan upgrades.
Moreover, I think the EOL policy and declarations must be documented explicitly 
on Apache web site.
Please share your feedback on revisting the EOL policy.
ThanksAnuj
