Started by core members of the original MySQL team, MariaDB actively works with outside developers to deliver the most featureful, stable, and sanely licensed open SQL server in the industry. An additional important advantage of using a UUID primary key instead of an Integer Autoincrement Primary Key is that you can worry less about exposing business information. The AUTO_INCREMENT value for an InnoDB table can be set for a table by executing the ALTER TABLE statement and specifying the AUTO_INCREMENT table option. 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. CREATE TABLE t1 (c1 INT PRIMARY KEY AUTO_INCREMENT, c2 INT) ENGINE=InnoDB; INSERT INTO t1 (c2) VALUES (FLOOR(1000*RAND())); INSERT INTO t1 (c2) SELECT FLOOR(1000*RAND()) FROM t1; -- repeat last insert until there are at least 1024 rows in t1 SELECT COUNT(*) FROM t1 AS a JOIN t1 AS b WHERE b.c1>a.c1 AND b.c2
