AWS Lambda Function Timeout While Processing SQS Messages Even with Increased Timeout Settings
Could someone explain I'm following best practices but Hey everyone, I'm running into an issue that's driving me crazy... I'm working with an scenario with my AWS Lambda function that processes messages from an SQS queue. Despite increasing the timeout setting of the Lambda function to 30 seconds, I still receive a timeout behavior (“Task timed out after 6.00 seconds”) during execution. Here’s the relevant portion of my Lambda function code: ```python import json import boto3 import time def lambda_handler(event, context): print("Received event: " + json.dumps(event)) sqs = boto3.client('sqs') for record in event['Records']: # Simulate processing time time.sleep(10) # Simulating a 10-second process # Assume we have a process_message function that could take time process_message(record) return { 'statusCode': 200, 'body': json.dumps('Processing complete!') } ``` I’ve set the Lambda timeout to 30 seconds in the AWS console, but the function continues to timeout at 6 seconds. I also checked the SQS message visibility timeout, which is set to 30 seconds, so that shouldn’t be the scenario. I also tried to create a dead-letter queue (DLQ) to capture failed Lambda invocations, but I haven't received any messages in the DLQ, indicating the messages aren't being processed at all before the timeout. Is there something I’m missing in terms of configuration? Could there be an scenario with the Lambda execution environment or my message processing logic? I would appreciate any help or insights on this. For context: I'm using Python on Windows. Is there a better approach? I'm using Python latest in this project. My development environment is Ubuntu 22.04.
