You have a database named db1 in an Azure Cosmos DB Core (SQL) API account.
You are designing an application that will use db1.
In db1, you are creating a new container named coll1 that will store online orders.
The following is a sample of a document that will be stored in coll1.



The application will have the following characteristics:
New orders will be created frequently by different customers.
Customers will often view their past order history.
You need to select the partition key value for coll1 to support the application. The solution must minimize costs.
To what should you set the partition key?

  1. orderId
  2. customerId
  3. orderDate
  4. id

Answer(s): B

Explanation:

If most of your workload's requests are queries and most of your queries have an equality lter on the same property, this property can be a good partition key choice. For example, if you frequently run a query that lters on UserID, then selecting UserID as the partition key would reduce the number of cross-partition queries.
