Is a VM running Cassandra with only 16GB for a staging agent sufficient enough?

Usually for Cassandra these options should be set in jvm-server.options:
-Xms16G
-Xmx16G

…but with these settings the Cassandra service dies on a VM with 16G RAM total.
Now can this be lowerd for a staging agent or is it really a must to use 32GB RAM on the VM?

Hi Dominik,

This is of course always very specific to the situation, but generally speaking, you should have no issues in a staging environment if you lower the JVM memory settings.
