I have a huge data table (15GB) where there are the columns
(1) - “""deviceId""" , simple column that repeat N Times
(2) - """DistanciaTotal""" , that is part of array using the comand """REPLACE(JSON_EXTRACT(A.attributes, '$.totalDistance') ,'.',',') as DistanciaTotal"""

I need take the MAX and MIN values DistanciaTotal by DeviceId

Is there a command that is possible run without overflow the server?

Today I'm doing this by extracting and concatenating in excel, but it's very suffer work

Thanks in advance
