With DynamoDB Streams and the data-transformation feature of Amazon Kinesis Firehose, you have a powerful and scalable way to replicate data from DynamoDB into data sources such as S3 and then analyse using Power BI
DynamoDB
Create lambda function to buffer items newly added to the DynamoDB table and then send a batch of these items (JSON-formatted source records) to Amazon Kinesis Firehose delivery stream
This lambda function takes all messages in the DynamoDB stream and forwards them to the Firehose delivery stream.
