DynamoDB TTL on item collections

Question

hello, I would like to know how TTL column works in case we are working with item collections. For example, if wanted to add a TTL column to this schema, I'm not sure about how to share the same value across all the records related to the same PK.

Thanks.

Answer

A TTL is associated with a single item, never an item collection. You'll need to add a TTL attribute on each item.
