InfluxDB does not store null values in any way. There is no performance or storage penalty from having a field that appears on only one or some points in a measurement.
Note that if you explicitly write field=0, or field="0" or field="null" the system will store that as a number, string, and string, respectively. A point with field= will be invalid and fail to write. A point that does not mention a field at all will store nothing for that field.
