What should you use?

You have an Azure Cosmos DB Core (SQL) API account that uses a custom conflict resolution policy. The account has a registered merge procedure that throws a runtime exception.

The runtime exception prevents conflicts from being resolved.

You need to use an Azure function to resolve the conflicts.

What should you use?
A . a function that pulls items from the conflicts feed and is triggered by a timer trigger
B. a function that receives items pushed from the change feed and is triggered by an Azure Cosmos DB trigger
C. a function that pulls items from the change feed and is triggered by a timer trigger
D. a function that receives items pushed from the conflicts feed and is triggered by an Azure Cosmos DB trigger

Answer: D

Explanation:

The Azure Cosmos DB Trigger uses the Azure Cosmos DB Change Feed to listen for inserts and updates across partitions. The change feed publishes inserts and updates, not deletions.
