Lambda Invocation Models
Three distinct paths with different contracts: synchronous (RequestResponse — caller waits, caller handles errors, e.g. API Gateway/function URLs), asynchronous (Event — Lambda queues internally, returns 202, retries twice), and poll-based via an event source mapping that reads batches from streams and queues on your behalf.
