对于Cosmos Db，每个数据库，每个帐户或每个订阅是否有任何限制（多少）集合？

Question

我想知道可以在cosmos数据库中添加的最大集合数。

Answer 1

Fortunately there are no limits in number of collections that can be added to a cosmos DB.

But be aware: Each collection is purchased! 5 collections are costs 5 times more than one collection. (if they all have the same RU/s).

A good pattern is to put all data into one single collection and add a .type property for each document. With that .type your query the data you want to get.

SELECT * FROM c WHERE c.type = <myDataType>
