ttl property
Input only.
The TTL (time to live) of the product. Note that this is only applicable to Type.PRIMARY and Type.COLLECTION, and ignored for Type.VARIANT. In general, we suggest the users to delete the stale products explicitly, instead of using this field to determine staleness. If it is set, it must be a non-negative value, and expire_time is set as current timestamp plus ttl. The derived expire_time is returned in the output and ttl is left blank when retrieving the Product. If it is set, the product is not available for SearchService.Search after current timestamp plus ttl. However, the product can still be retrieved by ProductService.GetProduct and ProductService.ListProducts.
Implementation
core.String? ttl;
