PubSub is not a product I work on, so apologize for lack of detail:
- PubSub is used by Google internally to power everything from Android notifications to Hangouts messages. So it's certainly proven.
- A lot of your questions are answered in docs:
https://cloud.google.com/pubsub/ https://cloud.google.com/pubsub/
https://cloud.google.com/pubsub/docs https://cloud.google.com/pubsub/docs
You can always reach out to me, and I can get you in touch with a PubSub SME.
- Pyxl101 11y agoI didn't see anything in the docs that touches on those subjects in detail (I did skim the docs looking for sections and pages that might contain answers to my questions before I posted), but please point me to the page that does if you know of one and I'd be interested to read it! I trust that your perceptions and information are accurate, but cite-able and reference-able information is also valuable.
- drewhk 11y agoI see this: https://cloud.google.com/pubsub/subscriber https://cloud.google.com/pubsub/subscriber In the "Delivery contract" section: "For the most part Pub/Sub delivers each message once, and in the order in which it was published. However, once-only and in-order delivery are not guaranteed: it may happen that a message is delivered more than once, and out of order." So it is at-least-once delivery as far as I see.
