Database administrators spend a considerable part of their lives adjusting and experimenting to improve DBMS performance. When it comes to diagnosing application lags and performance issues, a poorly performing database (and database query) is often the most common culprit. It can be seen that the following content does not completely determine the performance of MySQL. We just want to review the key points of the previous chapters and provide a starting point for discussion and analysis of performance optimization. Here are 17 key points for specific MySQL performance optimization: 1. First, MySQL (like all DBMS) has specific hardware recommendations. When learning and researching MySQL, using any old computer as a server will work. But for servers used in production, you should stick to these hardware recommendations. 2. Generally speaking, critical production DBMS should run on its own dedicated server. 3.MySQL is pre-configured with a series of default settings, and it is usually good to start with these settings. But after a while you may need to adjust memory allocation, buffer size, etc. (To view the current settings, use SHOW VARIABLES; and SHOW STATUS;.) 4.M

Introduction: Performance optimization index index points to a location in the database where specific data is located. Colleagues create an index on the column to arrange the information on the column. When the server needs to access this information for a query, it will know where to look because the index points to the relevant location. If a column is involved in querying, grouping, and sorting, the index will improve performance. Indexes with many duplicate values will not produce good results. You can use tables to join multiple non-unique indexes to improve performance. The more indexes, the better the performance is not necessarily. Adding an index does not necessarily improve performance.

5. Start using the Informix TimeSeries solution immediately
Introduction : IBM Informix provides native support for processing time series data. The TimeSeries data type available in IBM Informix helps reduce storage costs and improve performance when you select and load large amounts of time series data. In this article, you'll learn how to get started creating and loading time series data.

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
