mysql database optimized for ultra-sub-table

CREATE TABLE IF NOT EXISTS `table1` (  
`id` int(11) NOT NULL AUTO_INCREMENT,  
`name` varchar(50) DEFAULT NULL,  
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
  
CREATE TABLE IF NOT EXISTS `table2` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(50) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
  
INSERT INTO `table1` (`name`) VALUES('name1');
  
INSERT INTO `table2` (`name`) VALUES('name2');
 
CREATE TABLE IF NOT EXISTS `uTable` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(50) DEFAULT NULL,
INDEX(id)
) ENGINE=MRG_MyISAM DEFAULT CHARSET=utf8 UNION=(table1,table2) INSERT_METHOD=LAST AUTO_INCREMENT=1;
select id,name from uTable;
 INSERT INTO `uTable` (`name`) VALUES('name4');

Usage:
1. First build a part table: table1, and then build the operating table: uTable
2. table1 table data until certain conditions are met (or lot number of the larger space), rebuild a table Table2, reconstruction uTable table.
3. and so on.
Note: sub-table is only used to store data, do not directly operate, usually read only by inserting operation uTable query table can.
