That wasn't horrible at all. After testing, provided all goes well I can
submit this back to the main TWCS repo if you think it's worth it.
Either way do you mind just reviewing briefly for obvious mistakes?

I hope I can do as you suggest and leapfrog to 3.11 rather than two
stepping it from 3.7->3.11
Just having TWCS has saved me lots of hassle so it’s all good, thanks for
all you do for our community.

I'm sincerely sorry for the hassle, but for various reasons beyond, it's
unlikely I'll update my repo (at least me, personally). One fix is likely
to grab the actual java classes from the apache repo, pull them in and fix
the package names, and compile (essentially making your own 3.11 branch).

you are right, it won't even compile:

[ERROR] COMPILATION ERROR :

There’s a chance it will fail to work - possible method signatures changed
between 3.0 and 3.11. Try it in a test cluster before prod

Nevermind, I spoke to quickly. I can change the cass version in the
pom.xml and re compile, thanks!

Easiest approach is to build the 3.11 jar from my repo, upgrade, then ALTER
table to use the official TWCS (org.apache.cassandra) jar
Sorry for the headache. I hope I have a 3.11 branch for you.

Hi all, we're planning an upgrade from 2.1.5->3.11.3 and currently we have
several column families configured with twcs class
'com.jeffjirsa.cassandra.db.compaction.TimeWindowCompactionStrategy' and
with 3.11.3 we need to set it to 'TimeWindowCompactionStrategy'
Is that a safe operation? Will cas
Taking a step back and in case you are hosted on a cloud - We are entirely

According to the doc:

Is more information needed, for example from logs or verbose running? Is
anyone else seeing this behaviour?
Thanks.

unlogged batch meaningfully outperforms parallel execution of individual
statements, especially at scale, and creates lower memory pressure on both the
clients and cluster. They do outperform parallel individuals, but in cost of
higher pressure on coordinators which leads to more blocked Native
I think that is not possible. If currently both DC's are in use, you should
remove one of them (gently, by changing replication config), then change
num_tokens in removed dc, add it again with changing replication config, and
finally do the same for the other dc. P.S A while ago, there was a thr
Onmstester,
Thanks for the reply, but for both the DC’s I need to change my num_token
value from 8 to 256. So that is the challenge I am facing. Any comments.

IMHO, the best option with two datacenters is to config replication strategy to
stream data from dc with wrong num_token to correct one, and then a repair on
each node would move your data to the other dc Sent using Zoho Mail
