shows that you are also charged if you remap them too often (more then 100
times a month), this I didn't realize:

I'm looking to get a better feel for how people use Cassandra in practice.
I thought others would benefit as well so may I ask you the following five
questions:
1. Do the same people where you work operate the cluster and write the
code to develop the application?
2. Do you have
1. Do the same people where you work operate the cluster and write

Different teams. Infra separate , Dev separate.
2. Do you have a metrics stack that allows you to see graphs of
various metrics with all the nodes displayed together?

yes
2. Do you have a metrics stack that allows you to see graphs of

no

Hi
I would like to know is there any guideline for selecting storage device
(disk type) for Cassandra backups.
As per my current observation, NearLine (NL) disk on SAN slows down
significantly while copying backup files (taking full backup) from all node
simultaneously. Will using SSD disk o
1. Do the same people where you work operate the cluster and write

No, we have a small infrastructure team, and many people developing
applications using Cassandra

1. Do the same people where you work operate the cluster and write

Mostly. Ops vs dev, although there's some overlap

Yes, Prom
1. PaaS model. We have a team responsible for the deployment and
self-service tooling, as well as SME for both development and Cassandra
operations. End users consume the service, and are responsible for app
development and operations. Larger apps have separate teams for this,
smaller apps have a s
I think it would also be interesting to hear how people are handling
automation (which to me is different than AI) and config management.
For us it is a combo of custom Java workflows and Saltstack.

Yes it can race; if you don't want to race, you'd want to use SERIAL or
LOCAL_SERIAL.

I'm reading the OP as doing this from a single server, if that's the
case QUORUM / LOCAL_QUORUM will work.
