Kong Vitals | What Role DB Playing here

Hello All,

We are planning to use Kong Vitals offering come long with enterprise, as per the documentation it’s require any one of the database to work , but from documentation it is not clear how much data Kong store and where. Do any one knows the retention period of this data and how much storage its require to store this data .

Also if I go with Prometheus option to configure Vitals do I still need Database ?

Any pointer here will be highly appreciated.

Thanks & Regards
Prakash
