If you want to partition the employees table based on emp_no and you want to keep 100,000 employees in one partition, you can create it like this:
mysql> CREATE TABLE `employees` ( `emp_no` int(11) NOT NULL, `birth_date` date NOT NULL, `first_name` varchar(14) NOT NULL, `last_name` varchar(16) NOT NULL, `gender` enum('M','F') NOT NULL, `hire_date` date NOT NULL, `address` varchar(100) DEFAULT NULL, PRIMARY KEY (`emp_no`), KEY `name` (`first_name`,`last_name`)) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4PARTITION BY RANGE (emp_no)(PARTITION p0 VALUES LESS THAN (100000) ENGINE = InnoDB, PARTITION p1 VALUES LESS THAN (200000) ENGINE = InnoDB, PARTITION p2 VALUES LESS THAN (300000) ENGINE = InnoDB, PARTITION p3 VALUES LESS THAN (400000) ...
