Merchants are struggling to set up Grafana in high availability configurations, specifically when using multi-master MySQL/MariaDB clusters or shared NFS for SQLite. There is uncertainty regarding database schema compatibility and the ability to connect to multiple database hosts.

is it possible (or is it safe) if I have 2 Grafana instances simultaneously sharing the same data directory with grafana.db in it? Or do I actually need to switch to MySQL or Postgres?
Spent some time in connecting grafana to multi master mariadb galero cluster but no success. I saw it created multiople records instead of 1 in tables with no primary key.
when I try to add more than one host, it doesn’t work. Is this possible?
do we need to have any change in grafana schema to enable it to work with multi master mysql setup?
