We are about to install more memory in our DR instance, we will have about 350GB of physical memory, we would like a recommendation from BC/Vertica on how much memory "should" we expose to the OS for Vertica? Possibly there is some downside to "too much" memory?
There is no limit on memory per Vertica host
Release : 21.2
Component : IM Data Storage
Vertica automatically uses upto 95% of the max memory on the box, after reboot.
general resource pool is set to 95% maxmemorysize OOTB. Nothing to do when adding more memory to DR boxes.
