问题描述: 普通台式机,采集数据,表中已经有1000万数据量。 采集回来的数据插入表中的时候很慢,每条约100毫秒。 解决方法:
1、加大mysql配置中的bulk_insert_buffer_size,这个参数默认为8M bulk_insert_buffer_size=100M
2、改写所有insert语句为insert
问题描述:

采集回来的数据插入表中的时候很慢,每条约100毫秒。
解决方法:
1、加大mysql配置中的bulk_insert_buffer_size,这个参数默认为8M
bulk_insert_buffer_size=100M
2、改写所有insert语句为insert delayed
这个insert delayed不同之处在于:立即返回结果,后台进行处理插入。
还有一个技巧是在一跳insert中插入多条数据,类似insert into tablename
values('xxx','xxx'),('yyy','yyy'),('zzz','zzz')...;但是在我采集程序中改sql比较麻烦,故未采用
