A Cosmos DB-triggered function must not reprocess the entire container on first deployment. Which setting controls this?

  1. A StartFromBeginning / start-from-time on the trigger (correct answer)
  2. B maxItemsPerInvocation
  3. C The lease container name
  4. D The partition key

Shortcut: The Cosmos DB trigger reads the change feed. Configuring it to start from now rather than the beginning prevents an initial replay of all existing documents.
