问题
I'm using .net core Cosmos Db Client nuget Microsoft.Azure.Cosmos v3.4.4
I need to query across partition 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
Can you help me?
Thanksss!
回答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.

If you are using CosmosDB SDK v3 Cross Partition Queries are enabled by default.
There is no longer "FeedOptions", instead EnableCrossPartitionQuery is set automatically based on the query
