有没有人使用过包含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

像 MongoDB 和 db4o 这样的对象数据库最近得到了很多关注.每个和他们一起玩的人似乎都喜欢它.我猜他们在他们的示例应用程序中处理了大约 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.

有没有人尝试过使用包含大量数据(例如 50GB 或更多)的对象数据库?您是否仍然能够对它执行复杂的查询(例如从搜索屏幕)?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?

我只是好奇.我想尝试一下对象数据库，但我需要知道它是否适用于示例应用之外的其他东西.

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

有人刚刚投入生产，MongoDB 中有 12 TB 的数据.我之前知道的最大的是 1 TB.很多人在 Mongo 中保存了大量的数据.

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.

请务必记住，Mongo 的工作方式很像关系数据库: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() 并联系 用户列表 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.
