Grafana-Zabbix integration : Which database is good

We have integrate with zabbix-grafana. As, we are collecting huge data in zabbix so we want to monitor mostly from grafana. so it requires lots of data from grafana as well.
So, is default sqlite3 DB is ok for grafana?
or we will use mysql/postgresql for this purpose?

Hi, I’m using without problem zabbix (vers. 4.0.1) for monitoring (~ 100.000 item) integrated with a graphical view through Grafana (vers 5.4.3).
Database is MySQL.
Sometimes my Grafana Panel has an high refresh time (< 5 sec. ) and I have not detected slowdowns or problems.
