Azure Cosmos DB是否不支持MongoDB/Mongoose唯一索引? [英] Does Azure Cosmos DB not support MongoDB/Mongoose unique index?

问题描述

在Mongoose中使用唯一约束，例如:

Using a unique constraint in Mongoose like:

email: { type:String, unique:true }

似乎不起作用.我可以用同一封电子邮件保存多个用户.

doesn't seem to work. I can save several users with the same email.

创建唯一索引是否需要做些什么?

Is there something I need to do to create a unique index?

推荐答案

当今，Cosmos DB的MongoDB API中不支持唯一索引.创建索引时不能指定unique:true.

Unique indexes are not supported today, in the MongoDB API for Cosmos DB. You cannot specify unique:true when creating an index.

您需要在应用层中实现此功能.

You'd need to implement this in your app tier.

编辑-如前所述，该代码于2017年11月通过MongoDB API正式发布.

EDIT - As pointed out, this was officially released as of November 2017, with the MongoDB API.
