How to use DynamoDB Stream to trigger events nearly real-time data when DynamoDB table items are changed

Using Amazon DynamoDB and Amazon DynamoDB Stream can be a very nice way to track all events happing in a single DynamoDB table if you need to do something on it, can be a way around inner joins, dump backup of all entries into a version database, S3 bucket or what else you can think about here, it's only your free mind there stop you to use it, but think about what you can use it to before you just enable, it have a cost-price to write and read from the DynamoDB Stream it's not high but no reason to pay if you did not need it.
