A programming error in a script resulted in us preparing and uploading a Line Protocol file which included some invalid field key/value pairs; the file specified some fields with value 0 but the fields should not have been included at all.
The result is that a
SHOW FIELD KEYS on the database shows many more fields than are appropriate for the measurement, and
SELECT on a measurement series produces many more columns of output than we want. (Of course, we can specify the columns to display but * is much quicker to type!)
Is there some way to delete the incorrect fields from the measurement? (The fields in question need to be removed from all series in the measurement.)
