I have an AWS Lambda function to read from an SQS queue. The lambda logic is basically to read off one message from SQS and then it processes and deletes the message. Code to read the message being something like.
ReceiveMessageRequest messageRequest =
new ReceiveMessageRequest(queueUrl).withWaitTimeSeconds(5).withMaxNumberOfMessages(1);
Now my question is what is the best way to trigger this lambda and how does this lambda scale for instance, if there are let's say 1000 messages in the queue so will there be a 1000 lambdas running together, since in my case one lambda can read only one message off the queue.
Any pointers on best practices around this kind of design.
