通常情况下,建议将bulk_insert_buffer_size设置为插入操作单个数据行的平均大小的两倍。如果插入操作的数据行比较大,可以适当增加这个值。一般来说,建议将bulk_insert_buffer_size设置为16MB到64MB之间。 设置bulk_insert_buffer_size 要设置bulk_insert_buffer_size参数,可以通过在MySQL配置文件中添加以下内容来完成: [...
要修改bulk_insert_buffer_size值,可以使用以下SQL语句: SETGLOBALbulk_insert_buffer_size=<新值>; 1. 其中,<新值>是你想要设置的新的bulk_insert_buffer_size值。执行以上命令后,MySQL服务器会将新的值生效。 3.4 验证修改结果 为了验证修改结果,可以再次使用步骤3.2中的SQL语句来获取当前的bulk_insert_buffer_...
你可以通过以下 SQL 语句来修改 bulk_insert_buffer_size 的值: sql SET GLOBAL bulk_insert_buffer_size = new_value; 其中new_value 是你想要设置的新大小(以字节为单位)。例如,要将 bulk_insert_buffer_size 设置为 256MB,你可以执行以下命令: ...
