10 recommended articles about library configuration
MySQL New Version Selection The company mainly used the mysql5.5 version in the early days. This year we built the database configuration center and mainly promoted the mysql5.6 version. The performance and functions have been improved to a certain extent. Mysql5. 6 can also support gtid, but it cannot switch between gtid mode and normal mode online. At the same time, the synchronization performance of 5.6 is still unsatisfactory. It can only start parallel replication in the case of multiple DBs, which is difficult to do in business. Guaranteed, so once the write operation is intensive, slow synchronization will be a serious problem; therefore, I have been considering upgrading MySQL recently. One of the first problems faced when upgrading MySQL is to choose a suitable version. First, we consider using mysql5 .7 and 5.7 have been released in multiple official versions this year. They are currently used in a wide range of applications and can be considered for use in the official environment. So we conducted an online comparison test and found that there was a big gap in performance between mysql5.7 and our online version of mysql5.6 (perhaps it was because some parameters were not adjusted well, 5.7 is indeed much more complicated). At the same time, the company has frequently experienced some log storage issues recently

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.

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.

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 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 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.
