Hi,

When I create a query and configure the minimum time interval to be the whole duration of the time filter I’m still seeing two rows where I expect to see only one. I’ve faced this same issue with influxdb but upon reading at influxdb github issues I understood that it was a design characteristic of that database however seeing the exact same issue using mysql made me believe I’m the one doing something wrong here.
