Article Introduction：innodb is one of the database engines of mysql. It is now the default storage engine of mysql and one of the standards for binary release by mysql AB. The innodb storage engine is fully integrated with the MySQL server. The innodb storage engine maintains its own buffer pool for caching data and indexes in main memory.

Article Introduction：InnoDB is one of the database engines of MySQL. It is now the default storage engine of MySQL and one of the standards for binary releases by MySQL AB. InnoDB adopts a dual-track authorization system, one is GPL authorization and the other is proprietary software authorization. InnoDB is the preferred engine for transactional databases and supports transaction security tables (ACID); InnoDB supports row-level locks, which can support concurrency to the greatest extent. Row-level locks are implemented by the storage engine layer.

Article Introduction：InnoDB is a general-purpose storage engine that balances high reliability and performance. Starting with MySQL 5.6, InnoDB is the default storage engine for MySQL. InnoDB can be used for multiple purposes. Here are some of them - It can be used for transactional purposes i.e. all ACID properties. InnoDB can be used for row-level locking, which means it provides higher performance compared to MyISAM. InnoDB can be used for large buffer pools of data and indexes. InnoDB can be used when we need better performance than MyISAM. MyISAM is the default storage engine of the MySQL relational database management system before version 5.5. MyISAM can also be used for various types of purposes. MyISAMeasy

Article Introduction：Differences: 1. MyISAM does not support transactions, but InnoDB does. 2. InnoDB supports data row locking, while MyISAM does not support row locking and only supports locking the entire table. 3. InnoDB supports foreign keys, but MyISAM does not. 4. The primary key range of InnoDB is larger, up to 2 times that of MyISAM.

Article Introduction：In earlier InnoDB versions, since there was only one file format, there was no need to name this file format. As the InnoDB engine evolves, new file formats that are incompatible with earlier versions are developed to support new features. Today we will introduce the InnoDB row storage format.

Article Introduction：Two modification methods: 1. Use the SET statement to temporarily modify the default storage engine. The syntax is "SET default_storage_engine=innodb;". When the client is restarted, it will be restored to the original engine type. 2. Use the ALTER TABLE statement to modify the syntax "ALTER TABLE table name ENGINE=innodb;" to modify the engine type of the specified table to innodb.

Article Introduction：Comparing InnoDB and MyISAM1, storage structure MyISAM: Each MyISAM is stored as three files on the disk. They are: table definition files, data files, and index files. The name of the first file begins with the name of the table, and the extension indicates the file type. .frm files store table definitions. The extension of the data file is .MYD (MYData). The extension of the index file is .MYI (MYIndex). InnoDB: All tables are stored in the same data file (or multiple files, or independent table space files). The size of the InnoDB table is only limited by the size of the operating system file, which is generally 2GB. 2. Storage space MyISAM: MyISAM supports

Article Introduction：InnoDB is a storage engine that stores data in tables on disk, so our data will still exist even after shutdown and restart. The actual process of processing data occurs in memory, so the data in the disk needs to be loaded into the memory. If it is processing a write or modification request, the contents in the memory also need to be refreshed to the disk. And we know that the speed of reading and writing to disk is very slow, which is several orders of magnitude different from reading and writing in memory. So when we want to get certain records from the table, does the InnoDB storage engine need to read the records from the disk one by one? The method adopted by InnoDB is to divide the data into several pages, and use pages as the basic unit of interaction between disk and memory. The size of a page in InnoDB is generally 16
