I HAVE formulated an opinion on this. Further to what pauldix said, a push infrastructure seems more the way to go from my own experiences both as a consumer and would-be implementer of metric pipelines. It's far easier to put a pull-to-push system in front of a push infrastructure than to bolt on a push gateway in front of a pull infrastructure.. It's actually very bizarre IMHO when comparing to how people utilize Kafka and other pipeline supporting services.. To me, the pull has been the Achilles heel of prometheus. I haven't looked at it recently but shortly after it came out the push gateway, which you would have thought was where you were to push stuff, was not suitable as an actual push gateway and rolling your own was recommended.
