What is the minimum value for DEBUG_VOLUME_SIZE?

CrateDB Installation
1

Hi all,
I’m trying to setup CrateDB in a home-lab with storage constraints.

I’m using the crate-operator helm chart and, in the examples, the DEBUG_VOLUME_SIZE is set to 128Gb.

What is the minimum value that I can use?

Afaik this is used mostly for heap dumps, so the size should be at least the size of your configured heap for the biggest node. This should be the minimum, as the volume might also be used for other things, but not 100% sure

Thanks a lot.

BTW where can I find the heap configuration of a node?

In the crd it is defined as heapRatio e.g. heapRatio: 0.5 => 50% of the memory limits
