Question

A developer configures a Cosmos DB container with the DefaultTimeToLive property set to -1. Several items in the container have no individual 'ttl' attribute set, while a few items explicitly set their 'ttl' attribute to 3600. What is the resulting expiration behavior for the items in this container?

Accepted Answer

TTL is enabled on the container; items without a 'ttl' attribute never expire, while items with 'ttl' set to 3600 expire 3600 seconds after last modification.

Answer

TTL is disabled entirely because -1 turns the feature off, so no items ever expire regardless of their individual 'ttl' attribute.

Answer

All items expire immediately because a DefaultTimeToLive of -1 is treated as zero seconds.

Answer

Items without a 'ttl' attribute expire after the system default of 86400 seconds, while items with 'ttl' set to 3600 override that with 3600 seconds.
