海量日志入库
日志目录下有10个日志文件,每个文件压缩后大约60M左右,文件后缀是.gz,如a.gz、b.gz等,文件中行的内容是id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,
id=2112112,[email protected],等等其它,

现在是想把这个目录下的每个文件的所有内容insert到数据库中,数据库中的表,是通过email分表的,大约是log_1,log_2,一直到log_1000的分表的,请问下详细的解决方案,比如说怎么样能保证到每个文件在很快的时间内入库,使得脚本执行更有效率
先贴一段代码

上面的代码执行起来,很慢,不可忍受,请大牛帮忙
------解决方案--------------------
表类型修改为:InnoDB,然后用事务实施,
还不行的话,换load file
------解决方案--------------------
对于innodb,开事物应该不会更慢,因为就算不开,每一条语句也都是一个事物,所以如果是只开启一个事物,最后commit一次,应该会比每条语句都begin一下,commit一下要快的(但我记得开了事物也不会快多少);但myisam在只有一个插入线程执行,并且表内总数据量比较小的场合下,肯定比innodb要快的,尤其是只有60M数据的环境下

load data infile 绝对会快很多,但你文件得先转换成另一个"xxx \t xxx"的形式,然后再load data infile,应该比一条条插入能快几倍
------解决方案--------------------
load data吧,load进去以后比对一下条数,别搞什么事务。出错几率很低的,即使出错了,删除以后重新导入也快。PS,这数据不叫海量数据。
------解决方案--------------------
不知道为什么要放在数据库中
按你的描述,数据文件展开后,每个在 60*20M左右,甚至更高
你一条一条的插入,不慢才怪呢
------解决方案--------------------
历史数据入库,只是一次性工作。无所谓“效率”
你可以直接将文件导入 text 字段后,再由 update 指令拆分

如果不打算修改日志处理方式,那么将日志增量追加入库也只是一个定期工作(周期至少大于等于1天)
同样也没效率的概念
