The policy applied to the SQS queue is similar to this:
{ "Version" : "2008-10-17", "Statement" : [{ "Sid" : "topic-subscription-arn:aws:sns:us-west-2:599109622955:myTopic", "Effect" : "Allow", "Principal" : { "AWS":["*"] }, "Action" : ["sqs:SendMessage"], "Resource":["arn:aws:sqs:us-west-2:599109622955:myQueue"], "Condition" : { "ArnLike":{ "aws:SourceArn":["arn:aws:sns:us-west-2:599109622955:myTopic"] } } }] }
There might be a small time period immediately after subscribing the SQS queue to the SNS topic and updating the SQS queue's policy, where messages are not able to be delivered to the queue. After a moment, the new queue policy will propagate and the queue will be able to receive messages. This delay only occurs immediately after initially subscribing the queue.
