3.0.15 or 3.11.1
Hi All,
I want to upgrade from 2.x to 3.x.
I can definitely use the features in 3.11.1 but it's not a must.
So my question is, is 3.11.1 stable and suitable for Production compared to
3.0.15?
Thanks!

Some that come to mind…
Cassandra Storage Engine: CASSANDRA-12269, CASSANDRA-12731
Streaming and Compaction: CASSANDRA-11206, CASSANDRA-9766, CASSANDRA-11623,
Reintroduce off heap memtables – CASSANDRA-9472

For the security conscious, CASSANDRA-11695 allows you to use Cassandra's
authentication and authorization to lock down JMX/nodetool access instead
of relying on per-node configuration.

Hi,
Can you please provide dome JIRAs for superior fixes and performance
improvements which are present in 3.11.1 but are missing in 3.0.15.
In addition,could you also provide the probable implications of the open
memory leak issue in Cassandra 3.11.
CASSANDRA-13929: BTree$Builder / io.netty.util.Recycler$Stack leaking memory
<https://issues.apache.org/jira/browse/CASSANDRA-13929>
Is it still recommended to go for 3.11.
Thanks

There’s a tweak to TWCS in 3.11.1 that lets data expire faster, but I wouldn’t call it unstable in any version I’ve ever used it with. I’ve deployed it on 2.0, 2.1, 2.2 [1], and used it in every version of C* that we’ve shipped it, and have never had an issue.
I would put 3.11.1 in prod over 3.0, there’s a number of performance improvements and a few nice features that make it worth it. Off the top of my head, off heap memtables, a nice LIMIT optimization, and more flexible allow filtering options are all nice.

Thanks Guys!
Sorry for the late reply.
I'm interested in TWCS where I understand is more stable in 3.11.1 than in
3.0.15, tombstone compaction and slow logs.
I don't plan to use MVs and SASI in the near future, as I understand are
not Production ready.
Is it okay to use the above features?

Use 3.11.1 and don't use any 3.0.x or 3.x features.
3.11.1 is effectively three sequential patch releases, and the tick-tock
releases offered a number of superior fixes and performance improvements
over what was done in 3.0.x.
Introduce the use of new features later on, one at a time, after thorough
testing and staging.

It might help if you let us know about which 3.11 features you are interested. As I hear it, some of the features may not be PR ready (like materialized views). In my opinion, it seems that 3.0.15 is the more stable way to go. However, I have not been testing 3.11, so my thoughts are more based on what others have experienced, not my own experience.
