Re: Partition on range date with/without primary key

Please use SHOW CREATE TABLE, not DESCRIBE, to show the table structure.

Do not drop the PRIMARY KEY, instead arrange for the date to be part of the PRIMARY KEY.

Is data_id AUTO_INCREMENT?

How about:
PRIMARY KEY(date_time, data_id),  -- PK must be unique
UNIQUE (data_id) -- presumably this constraint is true?

Do you have other significant SELECTs?
