// 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 Time To Live (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/TTL.html)
// in the Amazon DynamoDB Developer Guide.
