The Code is as follows: Create table 'Article _ view '( 'Article _ id' int (11) not null, 'View' int (11) not null, Primary key ('Article _ id ') ) ENGINE = InnoDB; In this way, although the pressure on the article table is shared, every time a process requests an update, a global mutex lock is generated, which can only be serialized and cannot be parallel. There will b

Dynamic planning.To a fish pond must pass through the former fish pond, and can not be returned after passing.
