Enable query across partitions on Microsoft.Azure.Cosmos.Client

Question

I'm using the .NET Core Cosmos DB Client NuGet package Microsoft.Azure.Cosmos v3.4.4

I need to query across partitions, but I haven't found how to do this like FeedOptions.EnableCrossPartitionQuery as described in the following article https://docs.microsoft.com/en-us/azure/cosmos-db/how-to-query-container

How do I enable cross partition queries?

Answer 1

Cross partition queries are enabled by default in V3.

If you do specify a PartitionKey in the QueryRequestOptions, it becomes a single partition query.

The v3 SDK sets the EnableCrossPartitionQuery automatically based on the query and QueryRequestOptions.PartitionKey value. There is no need to set it in v3.
