Does MySQL automatically handle deleted row cleanup, or is it necessary to periodically do this manually for tables with a lot of deletions? If it's manual, what are the SQL commands to do this?
Also, what happens when changes are made to a field definition? From, say, int to smallint, or tinyint to int, or varchar(255) to varchar(10)? Do temporary tables get created and the data copied over, or does unused space end up in the data files, to be collected later?
