Simple lambda to replay a sqs dead letter queue's messages into its original queue.
Create a new lambda with sqs-deadletterqueue-replayer-lambda.py.
Your lambda's timeout must be at least 30 seconds to work properly.
The lambda must be called with an event like this one :
{
"target_queue_name": "test-queue",
"source_queue_name": "test-queue-deadletter"
}The lambda will attempt to send as many documents as possible from test-queue-deadletter to test-queue. Succesfully sent messages will be deleted from the source queue.
