 ## Set time to live on an item
 
 In addition to setting a default time to live on a container, you can set a time to live for an item. Setting time to live at the item level will override the default TTL of the item in that container.

 ## Reset time to live
 
 You can reset the time to live on an item by performing a write or update operation on the item. The write or update operation will set the `_ts` to the current time, and the TTL for the item to expire  will begin again. If you wish to change the TTL of an item, you can update the field just as you update any other field.

 ## Turn off time to live
 
 If time to live has been set on an item and you no longer want that item to expire, then you can get the item, remove the TTL field, and replace the item on the server. When the TTL field is removed from the item, the default TTL value assigned to the container is applied to the item. Set the TTL value to -1 to prevent an item from expiring and to not inherit the TTL value from the container.

 ## Disable time to live
 
 To disable time to live on a container and stop the background process from checking for expired items, the `DefaultTimeToLive` property on the container should be deleted. Deleting this property is different from setting it to -1. When you set it to -1, new items added to the container will live forever, however you can override this value on specific items in the container. When you remove the TTL property from the container the items will never expire, even if there are they have explicitly overridden the previous default TTL value.
