Re: Which version is stable enough for production environment?

[Benjamin Roth]

These issues exist since the very first implementation of MVs in *ALL* CS
versions.
If you want to use MVs, you may want to wait until these issues are
officially resolved. For testing or pre-prod, you could checkout
https://github.com/Jaumo/cassandra/commits/CASSANDRA-12905. I have fixed
these issues inofficially and have this version currently running on our
own cluster - but no warranties.

If you don't need MVs, you can for example use the Instaclustr 3.7 LTS
version as announced earlier in this thread.

Re: Which version is stable enough for production environment?

[Hugo José Pinto]

All,

Many thanks for this enlightening thread.

We're about to go live with a client for a pre-production environment, and
must decide on which 3.x version to use. We will probably need to perform
regular repairs, so we are obviously worried about both CASSANDRA-12905 and
CASSANDRA-12888 that Benjamin referred to.

Hence, the two golden questions:

1) Are these issues already present in 3.0.x?

2) What would be the best 3.x version to put in production at this moment?

Many thanks for any help you can come up with,

Thanks. I left some comments.

LeveledCompaction: Have you checked if there where major changes in the
LeveledStrategy between 2.x and 3.x?

I am curios cause I use 3.10 (trunk) in production.

For anyone who is planning to use MVs:
They basically work. We use them in production since some months, BUT (it's a

Like I said,

test in a lower environment first with your data model to be sure.

Re: Which version is stable enough for production environment?

[Benjamin Roth]

I didn't mean to criticise you. It was meant as a notice for all of those
who are planning to use MVs.

I already made proposals to solve these issues on the dev list and plan to
test them on our own cluster during the next days. I am currently working
heavily on this as we have big trouble bootstrapping new nodes on our 3.10
cluster - due to these known issues.

JFYI.

Yes Benjamin, no one said it wouldn't. We're actively backporting things as
we get time, if you find something you'd like backported raise an issue and
let us know. We're well aware of the issues affecting MVs, but they haven't
really been solved anywhere yet.

Re: Which version is stable enough for production environment?

[Benjamin Roth]

Hi Brooke,

Just had a quick look on your code and I will promise that your LTS version
will have the same issues with MVs as any other version.
For details check CASSANDRA-12905 or CASSANDRA-12888.

Re: Which version is stable enough for production environment?

[Brooke Jensen]

2.1 will be end of life soon.

We have a number of customers running 3.7 in production and it's quite
stable. However you should always test in a lower environment first with
your data model to be sure.

If you're interested, we have made available a patched version of 3.7
<https://www.instaclustr.com/blog/2016/10/19/patched-cassandra-3-7/> which
backports some key patches from 3.9.

Re: Which version is stable enough for production environment?

[Benjamin Roth]

What are the compaction issues / hint corruprions you encountered? Are
there JIRA tickets for it?
I am curios cause I use 3.10 (trunk) in production.

For anyone who is planning to use MVs:
They basically work. We use them in production since some months, BUT (it's
a quite big one) maintainance is a pain. Bootstrapping and repairs may be -
depending on the model, config, amount of data - really, really painful.
I'm currently investigating intensively.

3.0 has "off the heap memtable" impl removed and if you have a requirement for 
this,its not available.If you don't have the requirement 3.0.9 can be tried 
out. 3.9 version we did some testing and find lot issues in compaction,hint
