As a present search Googler, it's more of a testament to how easy it is to run a service that doesn't need to accept transactional writes from users, contains little or no private data, and where >1% taint is acceptable.
- double-a 6y agoGlad to see at least some folks in Search understand this :)
- technoplato 6y agoSorry, what is taint in this context?
- make3 6y agoProbably, missed elements
- asdfasgasdgasdg 6y agoYep, that's it.
- person_of_color 6y agoNo private data? Isn’t search personalized?
- asdfasgasdgasdg 6y agoI can't really comment on that, except to say that the way it works is a much easier problem than how gmail works.
- ma2rten 6y agoSearch ads require transactional writes. But actually, as far as I remember big outages at Google in the past have been things like "someone pushed the wrong router config" and not "our database got overloaded". Maybe search is just more conservative?
- asdfasgasdgasdg 6y agoSearch ads is a completely different system than search. They don't share tech stacks or reporting chains.
- btown 6y agoDo ads truly require transactional writes though, rather than eventually consistent log-append writes?
- pradn 6y agoI have the same question. I suppose ads billing might have transactional requirements, but that's separate from search itself.
- arcticfox 6y agoI worked at Bing/Yahoo. There are two mechanisms helping keep search up when considering ads: -> Search engine pages can be served w/ no ads, or even no personalization if components are down or lagging -> Ad logs can be lost if necessary, since we'd under-bill in that case, which would be our own problem. That happened a small handful of times while I was there. The billing system is indeed transactional, but has less need for 100% up-time and 0 latency in comparison to search. Not nearly as big of a deal if there's an hour delay on billing ads as compared to search being down for an hour.
