有没有人使用带有大量数据的对象数据库? [英] Has anyone used an object database with a large amount of data?

问题描述

诸如MongoDB和db4o之类的对象数据库最近得到了广泛的宣传.和他们一起玩的每个人似乎都喜欢它.我猜他们在示例应用程序中正在处理大约640K的数据.

Object databases like MongoDB and db4o are getting lots of publicity lately. Everyone that plays with them seems to love it. I'm guessing that they are dealing with about 640K of data in their sample apps.

是否有人试图使用包含大量数据(例如50GB或更多)的对象数据库?您是否仍然可以对它执行复杂的查询(例如在搜索屏幕上)?它与您通常选择的关系数据库相比如何?

Has anyone tried to use an object database with a large amount of data (say, 50GB or more)? Are you able to still execute complex queries against it (like from a search screen)? How does it compare to your usual relational database of choice?

我很好奇.我想让对象数据库陷入困境，但我需要知道它是否还能在示例应用程序之外的其他方面工作.

I'm just curious. I want to take the object database plunge, but I need to know if it'll work on something more than a sample app.

推荐答案

某人刚刚在MongoDB中使用12 TB的数据投入生产.我之前知道的最大容量是1 TB.很多人在Mongo中保存大量数据.

Someone just went into production with a 12 terabytes of data in MongoDB. The largest I knew of before that was 1 TB. Lots of people are keeping really large amounts of data in Mongo.

重要的是要记住，Mongo的工作原理非常类似于关系数据库:您需要正确的索引才能获得良好的性能.您可以在查询中使用explain()，并与用户列表联系以寻求帮助.

It's important to remember that Mongo works a lot like a relational database: you need the right indexes to get good performance. You can use explain() on queries and contact the user list for help with this.
