Which property should you change in the Function.json file of function1?

You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.

Upserts of items in container1 occur every three seconds.

You have an Azure Functions app named function1 that is supposed to run whenever items are inserted or replaced in container1.

You discover that function1 runs, but not on every upsert.

You need to ensure that function1 processes each upsert within one second of the upsert.

Which property should you change in the Function.json file of function1?
A . checkpointInterval
B. leaseCollectionsThroughput
C. maxItemsPerInvocation
D. feedPollDelay

Answer: D

Explanation:

With an upsert operation we can either insert or update an existing record at the same time.

FeedPollDelay: The time (in milliseconds) for the delay between polling a partition for new changes on the feed, after all current changes are drained. Default is 5,000 milliseconds, or 5 seconds.
