Commonly used MySQL storage engines [Summary]
This article mainly introduces to you what are the most commonly used MySQL storage engines? You can also refer to MySQL Video Tutorial or MySQL Manual to learn more.
The following storage engines are the most commonly used:
MyISAM: The default MySQL plug-in storage engine, which is one of the most commonly used storage engines in Web, data warehousing and other application environments. one. Note that the default storage engine of the MySQL server can be easily changed by changing the STORAGE_ENGINE configuration variable.
InnoDB: For transaction processing applications, has many features, including ACID transaction support. (Provides row-level locks)
BDB: A transaction engine that can replace InnoDB and supports COMMIT, ROLLBACK and other transaction features.
Memory: Saves all data in RAM, providing extremely fast access in environments where references and other similar data need to be quickly found.
Merge: Allows the MySQL DBA or developer to logically combine a series of equivalent MyISAM tables and reference them as 1 object. It is very suitable for VLDB environments such as data warehousing.
Archive: Provides the perfect solution for the storage and retrieval of large amounts of rarely referenced historical, archival, or security audit information.
Federated: Able to link multiple separate MySQL servers to create a logical database from multiple physical servers. Very suitable for distributed environments or data mart environments.
Cluster/NDB: MySQL’s clustered database engine is particularly suitable for applications with high-performance search requirements that also require the highest uptime and availability.
Other: Other storage engines include CSV (comma-separated references to files used as database tables), Blackhole (used to temporarily disable application input to the database), and the Example engine (for rapid creation of A custom plug-in storage engine helps).
So this article is an introduction to the commonly used MySQL storage engine. I hope to be helpful!

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.
