Greetings,
We are running Cassandra 3.11.2 in Kubernetes and use a run.sh to set some
environment variables and a few other things.
This script includes:
CASSANDRA_MIGRATION_WAIT="${CASSANDRA_MIGRATION_WAIT:-1}"

this but ca

Hi (yet again) Sergio,
Finally, note that we use this sidecar
<https://github.com/Stackdriver/stackdriver-prometheus-sidecar> for
shipping metrics to Stackdriver. It runs as a second container within our
Prometheus stateful set.

Greetings,
We are planning a Cassandra upgrade from 3.7 to 3.11.5 and considering a
change to the GC config.
What is the minimum amount of memory that needs to be allocated to heap

Thanks Ghiyasi.
