Hi SalientListener,
Good day!
As I mentioned in your other post ( https://portal.tutorialsdojo.com/forums/discussion/review-mode-set-2-question-5-question/ ), API Gateway alone cannot Group the individual calls from the smart meters. Therefore, it needs the Amazon Kinesis data stream to aggregate multiple records and process them in batches. Then, Lambda functions can be triggered by Kinesis streams, instead of directly invoking Lambda functions for each data point using API Gateway.
I hope this clarifies your question. If you have more queries, pls let us know.Regards,
Neil @ Tutorials Dojo
