How to shrink my history data storaged in grafana

my zabbix have been running for years, the main datasource is zabbix, and then elasticsearch and etc.
Now there’s more than 274G datas in “/usr/local/mysql/data/zabbix” ,which is too big for my grafana host storage:
101G history_uint.ibd
147G history.ibd

how should I shrink it? is there a housekeeper or something like that in grafana?

I too am concerned about my storage capacity and the rate the data is growing.
