The toString() function converts all values in the _value column to strings.

Supported data types: Boolean | Bytes | Duration | Float | Integer | Time | Uinteger
To convert values in a column other than _value, define a custom function
patterned after the function definition,
but replace _value with your desired column.

r._measurement == "mem" and
r._field == "used"
)
