Does AWS SQS trigger concurrent lambda functions?

I have an AWS Lambda that is triggered by SQS. Couple dozen lambdas will push message to that SQS. So I was wondering when SQS is flooded with messages does it automatically trigger lambda to create multiple instance of it and handle the messages? Or do I have to configure something else? Thanks

I am confused about "create multiple instance" part, do you mean multiple instances of "messages" or multiple instances of "queue" ? – Ersoy
Good info here: AWS Lambda function scaling – John Rotenstein
@Ersoy I meant multiple instances of Lambda function so that it could handle tons of messages from the queue – jarge
@jarge thank for the reply, then my answer explains it. – Ersoy

Yes it is possible. AWS documentation states that

A Lambda function can process items from multiple queues (one Lambda event source for each queue). You can use the same queue with multiple Lambda functions.
