DynamoDB TTL - when Items are removed

Question

Does dynanodb has a limitation taking upto 48 hours to delete expired rows ? http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/howitworks-ttl.html

Since I want to execute a Lambda when a row is deleted from dynamo db table, so that means my lambda trigger can take upto 48 hours ?

Commonly takes 24 - 48 hours to be deleted, but keep in mind those items with expired TTL could still appearing in queries and scans. To avoid "phantom reads" you can use a Filter Expression to check if the TTL value is greater than current date.
