Kenneth,
The only 4.x docs should go in trunk. If you would like to contribute docs to
the 2.x and/or 3.x releases, please make pull requests against branches for
those versions.
During normal development process, the docs should be updated in trunk. When a
release is cut from trunk, any further
I made sub directories “2_x” and “3_x” under docs and put a copy of the doc in
each. No links were changed yet. We can work on the files first and discuss
how we want to change the template and links. I did the pull request already.

If you're just trying to change an IP, you can just stop the node, change
the IP and restart the node and it'll be fine (change it everywhere).
Replacing a node is different: replacing is when a node dies, and you're
replacing it with a new node that doesnt have any data. The
-Dcassandra.replace_a
I found the issue. I was running the nodetool command from another user.
Sorry for the noise.
Thanks.

Hey,
I always thought that changing the IP address of a node requires to use the
same procedure as for a died node, which part of it consists in starting
Cassandra the -Dcassandra.replace_address option as indicated at

I am trying to upgrade Datastax Cassandra 4.8.14 to 5.0.12, which is

Yes, I agree, we should host versioned docs. I don't think anyone is
against it, it's a matter of someone having the time to do it.

We should still host versioned docs on the website however. Eit

The following won't address any server performance issues, but will allow
your application to continue to run even if there are client or server
timeouts:
Your python code should wrap all Cassandra statement execution calls in
a try/except block to catch any errors and handle them appropriate

Can you share your code snippet, how you are trying to save the entity

I agree with Jeff. I believe the _best_ part of Cassandra exists in its
networking , replication , and fault tolerance. The storage engine is as dumb
as disk or memory. If we can make it fast by replacing it , great. Maybe even
optimize it in JVM.
With new paradigms like blockchain entering int
I’ve used OpsCenter, New Relic, Splunk, and ELK and all of them have ways to
visualize what’s going on. Eventually I just forked a cfstats2csv python
program and started making formatted excel files which made it easy to spot
anomalies and filter keyspaces / tables across nodes. I have some basi
Then you need to make the cp yourself as I described.
