如果应用程序的插入操作主要是逐行进行的,而不是BULK插入方式,那么增加bulk_insert_buffer_size的值可能不会产生明显的性能改善。 此外,bulk_insert_buffer_size只适用于MyISAM和MEMORY存储引擎,对于InnoDB存储引擎无效。 总结起来,通过修改MySQL的bulk_insert_buffer_size参数,可以优化BULK插入操作的性能。在调整该参数时...
bulk_insert_buffer_size默认是8M,我们要把它调成100M或百兆以上,也不要太大。下面看调整个好的,如下图: 第三步:完成设置后,批量插入数据时使用多条模式。 INSERT INTO table (field1,field2,field3) VALUES ('a',"b","c"), ('a',"b","c"),('a',"b","c"); --- 方式2 ---...
