--
-- The @UpdateTimeToLive@ method enables or disables Time to Live (TTL) for
-- the specified table. A successful @UpdateTimeToLive@ call returns the
-- current @TimeToLiveSpecification@. It can take up to one hour for the
-- change to fully process. Any additional @UpdateTimeToLive@ calls for the
-- same table during this one hour duration result in a
-- @ValidationException@.
--
-- TTL compares the current time in epoch time format to the time stored in
-- the TTL attribute of an item. If the epoch time value stored in the
-- attribute is less than the current time, the item is marked as expired
-- and subsequently deleted.
--
-- The epoch time format is the number of seconds elapsed since 12:00:00 AM
-- January 1, 1970 UTC.
--
-- DynamoDB deletes expired items on a best-effort basis to ensure
-- availability of throughput for other data operations.
--
-- DynamoDB typically deletes expired items within two days of expiration.
-- The exact duration within which an item gets deleted after expiration is
-- specific to the nature of the workload. Items that have expired and not
-- been deleted will still show up in reads, queries, and scans.
--
-- As items are deleted, they are removed from any local secondary index
-- and global secondary index immediately in the same eventually consistent
-- way as a standard delete operation.
--
-- For more information, see
-- <https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html Time To Live>
-- in the Amazon DynamoDB Developer Guide.
