AWS Lambda Function Timeout when Triggered via API Gateway with Large Payloads
I'm currently working with an scenario where my AWS Lambda function times out when it's triggered via API Gateway, especially when handling larger payloads. The function is set to 10 seconds timeout, and I’m seeing the following behavior in the logs: ``` Task timed out after 10.00 seconds ``` The Lambda function is supposed to process JSON data received from an API call. Here’s a simplified version of my function: ```python import json def lambda_handler(event, context): # Simulate processing print('Received event:', json.dumps(event)) # Long processing to mimic the handling of large payloads payload = event.get('body') process_payload(payload) return { 'statusCode': 200, 'body': json.dumps('Success') } def process_payload(payload): # Simulate some processing delay import time time.sleep(12) # Simulating a long processing time ``` I have already tried increasing the timeout setting to 30 seconds in the AWS Lambda console, but the scenario continues. I also checked the API Gateway settings, and the payload size is about 5 MB, which is within the limits, but it seems to take longer than expected to process it. I have read that using AWS Step Functions could help manage longer processes, but that seems like overkill for this use case. Are there any best practices or optimization tips regarding Lambda functions that can help improve performance when handling larger payloads? Any guidance on this would be greatly appreciated.
