Thanks Alain for the help. I will give these options a try.

Ø I keep hearing that the minimum number of Cassandra nodes required to
achieve Quorum consensus is 4 I wonder why not 3? In fact, many container
deployments by default seem to deploy 4 nodes. Can anyone shine some light on
this?
I think it may be due to the following (note : I am assuming, he
And I’m not aware of any case where it’s a good idea to use SimpleStrategy
in Prod (be interested to hear if anyone else knows of one).
NetworkTopologyStrategy behaves the same as SimpleStrategy in the basic
case of one DC and Rack but gives you a good path to migrate to more
sophisticated topologi
For sensitive data, I'd recommend to use at least RF=3. Especially if you
plan to use CL QUORUM, for example if you want to ensure consistency.
If you use QUORUM and RF=2 then a single failing node will make your data
unavailable.

Thank you so much for answer.
So, in case of a high failure rate in my cluster, i have to increase the
replication factor or i have to use NetworkToplogy Strategy ?
That's it ?
Kindly.

If you are reading and none of the replicas is online you will get an
exception on the read (tried x replicas but 0 responded) and your read will
fail. Writes on the other hand are going to go through only if your write
consistency is ANY. If your write consistency is ONE or anything upwards,

Hi,
Please, if we choose a replication factor =2 (simple strategy), so, we have
two replicas of data on the ring.
What happen in the case of all nodes containing replicas are down ?
Thank you so much for help.
Kind regards.

I believe you could try using a fixed TTL (defined at the table le
Never mind, I used our internal ccm and then it works. I did brew install
ccm at the beginning, looks like there is some bug in that brew install
version.

Hi, I tried to use ccm to create a local cluster,
What I did is:
ccm create test
ccm populate -d -n 3
ccm start.
So by default, it should have 2100 to remote debugger at 127.0.0.1
