报表
我们测试本地数据库引擎性能
mysqlslap -a -e"myisam,innodb" --csv="c:/a.csv"
c:/a.csv文件
我们转换成图表形式
可以看出 myisam,innodb 混合测试时myisam性能更好些 读写时间更少
常用选项
Windows默认配置文件读取顺序:C:/WINDOWS/my.ini
C:/WINDOWS/my.cnf
C:/my.ini
C:/my.cnf
F:/mysql/5.6.16/my.ini
F:/mysql/5.6.16/my.cnf
-h 数据库host
-u 数据库用户名
-p 数据库密码
-P 数据库端口
--create-schema=name 测试的数据名
--create=name 测试的SQL语句或文件
--no-drop 测试后不删除schema
--only-print 仅显示将被运行的SQL语句
-c 客户端数量(并发量) 如:mysqlslap -c"10"或-c"10,100,1000"
-e 测试引擎 如:mysqlslap -e"myisam"或-e"myisam,innodb"
--number-of-queries=# SQL语句执行总次数 如:mysqlslap -a --number-of-queries="10"
-q 测试的SQL语句 如:mysqlslap -q"SELECT * FROM t1"
-i 迭代运行次数 如:mysqlslap -a -i"3"
-T 显示内存和CPU信息并退出 如:mysqlslap -a -T
-F SQL语句分隔符

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.
