Re: Stable Cassandra 3.x version for production

[Jeff Jirsa]

3.0.15 is likely fine for production, but like any database, you should
test it with your data in a test environment prior to deploying to prod.

I haven't personally used 3.11.1, though the important parts are likely
very similar to 3.0.15.

I regularly work with teams that have 3.11.{0.1} in prod, and would recommend 
it for new clusters.  

Avoid materialized views and SASI until you really understand how they work and 
their limitations.  MVs solve about one use case correctly, SASI is good if 
you’re querying a single partition *but* it’s missing a pretty important 
optimization of addressing rows directly, so if you’ve got huge partitions you 
pay a massive price for using them.  Check out 
https://issues.apache.org/jira/browse/CASSANDRA-11990 
 for details.

Hi

Which version of Cassandra 3.x is stable and production-ready?

Regards

RE: Stable Cassandra 3.x version for production

[Steinmaurer, Thomas]

Latest DSE is based on 3.11 (possibly due to CASSANDRA-12269, but just a guess).

For us (only), none of 3.0+/3.11+ qualifies for production to be honest, when 
you are familiar with having 2.1 in production.


· 3.0 needs more hardware resources to handle the same load => 
https://issues.apache.org/jira/browse/CASSANDRA-12269. Improved (close/back to 
2.1 level) in 3.11

· With 3.11.0 we are seeing the following memory leak (at least here, 
but possibly nobody else out there, cause the ticket gets close to zero 
attention *g*): https://issues.apache.org/jira/browse/CASSANDRA-13929

· From an operational perspective, the repair area got much more 
troublesome compared to 2.1 when introducing incremental repairs being the 
default in 2.2+

We stay on 2.1 for now.

Just my opinion.

Thomas

I know that people usually prefers to use the 3.0.x branch because that's the 
one that is underneath DSE.

I've never heard of anyone using Cassandra > 3.0.x on production.

Re: Stable Cassandra 3.x version for production

[Carlos Rolo]

DSE is already pushing 3.11 in 5.1

If you're going into 3.x either 3.11.1 or 3.0.15. I would recommend 3.11.1
to take advantage of a couple of features (ex: Slow query log) that you
don't have on 3.0.

If you're stable on 2.x and you don't need any new feature, you can leave
it there safely (although the latest releases are probably the last ones
you will see).
