Use DescribeTimeToLive with an Amazon SDK or CLI

To view Time to Live settings for a table

The following describe-time-to-live example displays Time to Live settings for the MusicCollection table.

aws dynamodb describe-time-to-live \
    --table-name MusicCollection

Output:

{
    "TimeToLiveDescription": {
        "TimeToLiveStatus": "ENABLED",
        "AttributeName": "ttl"
    }
}

For more information, see Time to Live in the Amazon DynamoDB Developer Guide.
