PARTITION "pruning" is not possible with a range. You could switch to range partitioning. You would probably have to add a column with the month because partitioning is picky about what it will do ranges over. Or you could use TO_DAYS() in the partition expression.

> `ID` int(64) NOT NULL AUTO_INCREMENT,
That does not give you a 64-bit INT. It gives you a signed 32-bit INT. See BIGINT. Consider UNSIGNED.

> `DDL_LAT` double NOT NULL DEFAULT '0',
> `DDL_LNG` double NOT NULL DEFAULT '0',
Probably overkill.
FLOAT gives you precision better than 6 ft. / 2 meters. DOUBLE gives precision of a few nanometers.

What does your other SELECTs look like?
