B. Use the TTL attribute in your table schema
C. Write a Lambda function to manage TTL
D. Apply a TTL policy in the IAM console

Answer 1

To set up Time To Live (TTL) in Amazon DynamoDB, you can use the TTL attribute in your table schema. DynamoDB automatically deletes expired items based on the TTL value.

Step-by-step explanation:

To set up Time To Live (TTL) in Amazon DynamoDB, you can use the TTL attribute in your table schema. When you enable TTL for a specific attribute, you specify a timestamp or a date and time for each item in the table. DynamoDB automatically deletes the expired items based on the TTL value. You can easily configure TTL by defining an attribute as the TTL attribute using the DynamoDB UpdateTable API or the AWS Management Console.

For example, if you have an attribute called 'expiration_time' in your table and you want to set a TTL of 7 days for each item, you can specify this attribute as the TTL attribute and DynamoDB will automatically delete items that are older than 7 days.
