MyISAM: This is the default type, which is based on the traditional ISAM type, ISAM is an abbreviation for indexed sequential access method (indexed sequential access methods), which is the standard way to store records and files. Compared to other storage engines, MyISAM has most of the tools for checking and repairing tables. MyISAM tables can be compressed, an

The difference between MySQL's storage engine MyISAM and InnoDB How do you usually choose these 2 types in a specific project? ------Solution-------------------- MyISAM: This is the default type, which is based on the traditional ISAM type, ISAM is an abbreviation for indexed sequential access method (indexed sequential access methods), which is the standard way

statements. These features increase multi-user deployment and performance. There is no need to expand locking in InnoDB, because row-level locking in InnoDB is suitable for very small space. InnoDB also supports foreign key forcing. In SQL queries, You can freely mix InnoDB

. If your data executes a large number of INSERT or UPDATE operations, InnoDB tables should be used for performance considerations. If you execute a large number of SELECT statements, MyISAM is a better choice. 2. I need to use transaction processing, but the original data table uses myisam and needs to be changed to

The main difference between the two types is that InnoDB supports transactional and foreign key and row-level locks. And MyISAM does not support.I use MySQL as a user point of view, InnoDB and MyISAM are more like, but from my current operation of the database platform to meet the requirements: 99.9% stability, conveni

-text indexing, MyISAM is usually a good choice because it is built in the system. However, we do not often test the 2 million rows of records. Therefore, even if it is slower, we can use Sphinx to obtain full-text indexes from InnoDB.The size of data is an important factor that affects your choice of storage engines.

Large-sized data sets tend to use InnoDB because they support transaction processing and fault recovery. Small DatabaseIt determines the duration of fault recovery. InnoDB can use

a few days to do these tasks. InnoDB only needs a few minutes. The habit of operating database tables may also be a factor that has a great impact on performance. For example, COUNT () can be very fast in the MyISAM table, but it may be very painful in the InnoDB table. Primary Key query will be quite fast in
