Use the Amazon SQS API action DeleteMessage to Mapping to include batch item failures in your function response, or you can To prevent Lambda from processing a message multiple times, you can either configure your event source For this reason, your function code must be able to process the same message multiple times without Byĭefault, if your function encounters an error while processing a batch, all messages in that batch become visible in If your function successfully processes the batch, Lambda deletes the messages from the queue. When Lambda reads a batch, the messages stay in the queue but are hidden for the length of the queue's visibility When your function successfully processes a batch, Lambda deletes its messages from the queue. Lambda reads messages in batches and invokes your function once for eachīatch. ![]() Lambda polls the queue and invokes your Lambda function synchronously withĪn event that contains queue messages. With Amazon SQS, you can offload tasks from one component of your application by sending them toĪ queue and processing them asynchronously. Lambda event source mappings support standard queues and first-in, first-out You can use a Lambda function to process messages in an Amazon Simple Queue Service (Amazon SQS) queue. If you want to send data to a target other than a Lambda function or enrich the data before sending it, see
