- 8Your comment is the only one clearly explaining how SNS and SQS can be combined. Thanks!Andriy– Andriy2020-10-19 11:06:18 +00:00Commented Oct 19, 2020 at 11:06
- I am a newbie to AWS, but has 3. changed since the answer was written? [docs.aws.amazon.com/sns/latest/dg/… Delivery Retries) Amazon SNS defines a delivery policy for each delivery protocol. The delivery policy defines how Amazon SNS retries the delivery of messages when server-side errors occur (when the system that hosts the subscribed endpoint becomes unavailable). When the delivery policy is exhausted, Amazon SNS stops retrying the delivery and discards the message—unless a dead-letter queue is attached to the subscription.buzztr– buzztr2021-03-22 09:05:57 +00:00Commented Mar 22, 2021 at 9:05
- @buzztr 3. hasn't changed; it refers to the consumer of the SQS becoming unavailable. That documentation you cite describes a new feature of SNS in which failure to deliver a message to the consumer(s) (in this case, the SQS) after exhausting your retries results in SNS putting that message put onto a dedicated SQS queue for to handle transmission error. This means instead of the message being lost entirely, you have it saved and can re-attempt transmission through the SNS topic at a later date.Hans Hermans– Hans Hermans2021-05-24 01:37:56 +00:00Commented May 24, 2021 at 1:37

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
