Question on VPA - Benefits of Using 'prometheus' for VPA Recommender --storage Option

[dongheeJeong]

Hello everyone,

I’m currently exploring the Vertical Pod Autoscaler (VPA) and considering the --storage option for the recommender component, which can be set to either checkpoint (default) or prometheus.

I understand that configuring prometheus might require additional setup and integration steps. Could someone please clarify the benefits of using prometheus over the default checkpoint method?

Specifically, I’m interested in understanding:

• What advantages does prometheus provide compared to the default checkpoint method?

If there are any documents or resources that cover this comparison, please point me to them.

Thank you so much for your time and assistance!
