Understanding AWS Lambda Event Source Mapping

Attending AWS re:Invent is always a highlight for me, and this year’s session, SVS407-R: Understanding AWS Lambda Event Source Mapping, turned out to be a goldmine of insights. As someone who builds and maintains event-driven architectures, I walked away with a deeper understanding of the complexities and best practices around Event Source Mapping (ESM), particularly in handling event streams from services like Amazon Kinesis, DynamoDB Streams, and Amazon SQS.
