Grafana HA with mysql database

I have 2 mysql DB which are in cluster for fail tolerance and i need to provide the mysql DB ip addresses in my grafana.ini to attain the HA .

i would like to configure mysql database cluster for my grafana HA setup.

Environment
grafana 8.1

the database config for the /etc/grafana/grafana.ini as follows:

[database]
ssl_mode = skip-verify
name = grafana
host = :3306
user = grafana
password = “”“been2long”""
type = mysql

should we provide the IP addresses of both the mysql DB in the same host field in the database section or are we allowed for single ip address for mysql .
