alter table app_log_Test drop PRIMARY KEY, add primary key (`id`, `dateCreated`);

Next, I can re-run my alter table to add the partitions I care about.

ALTER TABLE app_log_Test
PARTITION BY RANGE (TO_DAYS(dateCreated))
    (PARTITION p_invalid_date VALUES LESS THAN (0) ENGINE = TokuDB,
    PARTITION p_201809 VALUES LESS THAN (TO_DAYS('2018-09-01 00:00:00')),
    PARTITION p_201810 VALUES LESS THAN (TO_DAYS('2018-10-01 00:00:00')),
    PARTITION p_max_future_dates VALUES LESS THAN MAXVALUE);

If I need to add more partitions after that. I don't have to specify the partition scheme again I can just add the partition and its constraints.

ALTER TABLE app_log_Test
    REORGANIZE PARTITION p_max_future_dates INTO (
        PARTITION p_201811 VALUES LESS THAN (TO_DAYS('2018-11-01 00:00:00')),
        PARTITION p_201812 VALUES LESS THAN (TO_DAYS('2018-12-01 00:00:00')),
        PARTITION p_max_future_dates  VALUES LESS THAN MAXVALUE);

My table now looks like this.

show create table app_log_Test;
Create Table: CREATE TABLE `app_log_Test` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
