Yes, you're right and I was aware of that (not realising that your question
was more around what I would consider multi-region comms). My disconnect
now is around the
Hello,
I would like to understand how the writes happen when there is a node in
the cluster that is being decommissioned.
During the decommission process, the node will send the streams to the rest
of the nodes that it owns. what happened to the read and write of the data
that is owned by the
So a few things are true:
- Cassandra uses IP addresses for internal data structures (in released
versions), so duplicating IP nominally means stomping on the wrong host
- Cassandra also differentiates broadcast IP from listen IP (local IP)
- The broadcast IP is what the other DC is going to
Team,
Do we have option in open source to do encryption at rest in cassandra ?
Generally speaking, don't run mixed versions longer than you have to, and
don't upgrade that way.
Why?
* We don't support it.
* We don't even test it.
* If you run into trouble and ask for help, the first thing people will
tell you is to get all nodes on the same version.
Anyone that's doing so
That seems like a lot of unnecessary streaming operations to me. I think
someone said that streaming works between these 2 versions. But I would not use
this approach. Why not an in-place upgrade?

Thank you all for the suggestions.
I am not trying to scale up the cluster for capacity but for the upgrade
process instead of in place upgrade I am planning to add nodes with 3.11.6
and then decommission the nodes with 3.11.3.

Streaming operations (repair/bootstrap) with different file versions is usually
a problem. Running a mixed version cluster is fine – for the time you are doing
the upgrade. I would not stay on mixed versions for any longer than that. It
takes more time, but I separate out the admin tasks so
The nodes within one datacenter will talk on private IPs and for
communication across data center public ips are used. Does that answer
your question? or you are asking in terms of network layer.
As per this link
Let's consider a table with two columns of counter type:
cqlsh:ks> CREATE TABLE t(p int PRIMARY KEY, c1 COUNTER, c2 COUNTER);
cqlsh:ks> UPDATE t SET c1 = c1 + 1 WHERE p = 1;
We have one row now:
p | c1 | c2---++--
1 | 1 | null
My question is: should we treat the null counter (`c2`
Putting Cassandra aside, I'm curious to know how you envision that would
work from a network perspective. How would the connectivity between servers
work?

This isn't a direct answer to your questions but you might be interested in
the Kubernetes operator for Apache Cassandra [1] from DataStax. You can use
the cass-operator to deploy a C* 3.11.6 image to your Kubernetes cluster.
The docs are available here [2].
FWIW there are several other published

Technically you can. You'll be able to add 3.11.6 nodes to a 3.11.3
cluster. In fact, the reverse works too in my tests but I personally
wouldn't want to do it in production.

Rightly said by Surbhi, it is not good to scale with mixed versions as
debugging issues will be very difficult.
Better to upgrade first and then scale.

Are there any implication if I have similar set of private IPs in two data
centers. For example if I have A,B and C as private IPs in one data center
and I define A,B and C as my private IPs in other data center, does it
impact the cluster?

Hi
I want to run Cassandra container in GCP and want to orchestrate the containers
using Kubernetes.
I have a Cassandra image in my Docker Registry. Following the steps from the
following tutorial, I have created a cluster and have Cassandra running on it.
