Question

You are building an audit-and-replication pipeline on a Cosmos DB for NoSQL container. The downstream system must observe every intermediate change to each item — including updates that happened between reads — and must also be notified when items are deleted (so it can remove them from a search index). You will consume the change feed using the .NET SDK with the change feed processor. Which change feed configuration meets these requirements?

Accepted Answer

Use the change feed in all-versions-and-deletes mode, which surfaces intermediate updates and delete operations within the configured retention window.

Answer

Use the change feed in latest-version (default) mode, which delivers only the most recent version of each changed item and includes deletes.

Answer

Enable Time to Live (TTL) on the container so that deletes are emitted, then read the latest-version change feed for updates.

Answer

Query the container with SELECT * ORDER BY _ts on a timer, since the change feed cannot report deletes under any mode.
