"Google has THE ENTIRE INTERNET IN MEMORY AT ONCE"
Do they? really? or is that a gross oversimplification which clouds the facts to the point of meaninglessness as I suspect it is.
I am not qualified to say whether that is actually possible but it seems doubtful.
- jwilliams 18y agoMy understanding is that the search index (at least) is all in memory - Even if you're talking about just the index hashes, that's a lot of memory. I doubt that the actual content is - given the Google model there would be no point.
- shimon 18y agoI think there is perhaps a point in the text highlighting, where it shows you an excerpt from the page containing your search terms. To do that they need either a very complex index (or to optimize for the most popular queries) or full page text in-memory. Google has a lot of computers.
- jwilliams 18y agoYou could do that at the point you render the result... and only after the page scored highly enough. That wouldn't necessarily need to be in memory to perform.
- quasimojo 18y agoall irrelevant. the google web index is not a transactional system. most uses of oracle are.
