A container stores chat history that should be removed automatically after 30 days. What is the correct configuration?
- A A scheduled Azure Function issuing bulk deletes
- B Container-level TTL set to 2592000 seconds (correct answer)
- C A retention policy on the account
- D Analytical store TTL
Shortcut: Setting DefaultTimeToLive on the container expires documents automatically using leftover RUs. Per-document ttl can override it. This is far cheaper than issuing explicit deletes.
