I am using serverless framework. My Lambda function connects to DynamoDB table for updating item in table. Read & Write capacity units of table are 5 & auto_scaling is disabled. AWS Lambda function has 128MB memory allocated.
I have used Jmeter for performance testing.I have sent 1000 requests concurrently and some response giving me perfect output while other giving internal server error(502 Bad Gateway). i have also analyzed cloudwatch for logs and only get Task Timeout error. can anyone suggest me why i am getting this error and how to solve it?
