Trello如何在MongoDB中存储数据？ （每板收藏？） [英] How does Trello store data in MongoDB? (Collection per board?)

问题描述

Trello如何在MongoDB中存储他们的数据（卡）？

How does Trello store their data (cards) in MongoDB?

我读了（Trello如何快速展示历史？）他们的动作集合是最大的。因此，我假设他们不将所有的卡存储在一个巨大的集合中。

I read ( How does Trello show history so quickly? ) that their Actions collection is the largest one. Thus I assume that they do not store all cards in one gigantic collection.

唯一的其他逻辑解决方案似乎是每个板或每个用户的集合。但是他们有很多用户，我读过（ http：//www.mongodb .org / display / DOCS / Using + a + Large + Number + of + Collections ）收藏数量有限制，有些人建议不要使用大量的收藏。

The only other logical solution seems a collection per board or per user. But they have a lot of users and I read ( http://www.mongodb.org/display/DOCS/Using+a+Large+Number+of+Collections ) that there is a limit on the number of collections and some people advise against using a lot of collections.

我希望来自Trello团队的人能够服从这一点，我希望从一般社区解决这个问题也有一些想法。

I hope someone from Trello team will answear this AND I hope to get some ideas on solving this kind of a problem also from the general community.

推荐答案

Trello将所有的卡存储在一个集合中。集合在卡的板ID上划分。

Trello stores all of the cards in one collection. The collection is sharded on the card's board id.
