Transform and batch data to a DynamoDB table
In this project, a Step Functions state machine invokes a Lambda function to get data to be written to a DynamoDB Table. The Lambda function generates an array of JSON objects containing random sample data.
A Map state converts the JSON array to a BatchWriteItem compatible DynamoDB JSON Array. This data is then passed to a Distributed Map State which performs batching of 25 items. This batching is necessary to comply with the validation requirements of the BatchWriteItem API in DynamoDB.
