Can multiple Lambdas subscribe to SQS?

Only one of the functions will handle each message. If you want multiple functions to handle the messages, send them to SNS and then subscribe the different functions to the topic either directly, or using different queues. One queue per function.

Hi, Another possible pattern in your use case may be to trigger a Step Function from SQS and then have this Step Function orchestrate (parallel / sequential) the multiple lambdas if all of them need to run on each message.

See https://docs.aws.amazon.com/step-functions/latest/dg/sample-project-express-high-volume-sqs.html

The context of the Step Functions is a nice way to share the message across the various lambdas

Best,

Another way to have multiple Lambda functions (or other subscribers) receive the same message is to use Kinesis instead of SQS. Note that the cost will likely be higher and there are lower throughput limits but depending on what you want to do it might be suitable.
