在“Schema Inspector”窗口中,选择“Size”选项卡即可查看数据库的占用大小。 代码示例 下面是一个使用Python脚本查询MySQL数据库占用大小的示例代码: importpymysqldefget_database_size(host,port,user,password,database):connection=pymysql.connect(host=host,port=port,user=user,password=password,database=databa...

创建一个存储过程,用于查询表的大小: DELIMITER //CREATE PROCEDURE get_table_size(IN database_name VARCHAR(255), IN table_name VARCHAR(255))BEGINSELECT table_name, table_rows, data_length, index_lengthFROM information_schema.tablesWHERE table_schema = database_name AND table_name = table_name;...

对于Azure Database for MySQL - 灵活服务器,可以将innodb_log_size配置为 256 兆字节 (MB)、512 MB、1 GB 或 2 GB。 参数是静态的,需要重启。 备注 如果更改了innodb_log_file_size参数的默认值,请检查值show global status like 'innodb_buffer_pool_pages_dirty'的值是否保持030 秒,以避免重启延迟。
