InnoDB and MyISAM are the two most commonly used table types used by many people when using MySQL, each with its own pros and cons, depending on the specific application. The basic difference is that the MyISAM type does not support advanced processing, such as transaction processing, but InnoDB type support. Tables of

is an important factor in what kind of storage engine you choose, and large datasets tend to choose the INNODB approach because they support transactional processing and failback. The small database determines the length of time to recover, and InnoDB can use the transaction log for data recovery, which is faster. While MyISAM may take hours or even days to do t
