DynamoDB time to live per Item

Question

I have a requirement to expire items at a different time to live configuration. There are cases where items in the table won't expire of certain cases as well. In Cassandra, we can set time-to-live while writing at the record level. In DynamoDB I could only see the TimeToLive configuration at table level but not at the item level.

1. Is there a way to set TTL at item level while doing putItem or
2. What are the best practices to delete records with minimal effect on the overall system?

If there is no possibility to set TTL at the item level, I would like to fall back to the second option.

Answer 1

DynamoDB can do this at the item level in the table. At this level, you input the name of the attribute that has the value of TTL. Then each time you input something in the table, include the attribute name that you referred to dynamo DB to look after. Then after this when each item comes DynamoDB will automatically delete it within 24hr.

I hope this helps you.
