The irony of OP championing for “taste” in the age of mass produced slop, only to then post something that was likely produced by repeatedly reprompting with “no, again”
One reason is that there is no "good" search engine in China. The most popular one, Baidu, is like garbage compared to Google search. The most useful training data in Chinese would likely be from the social media and video sharing platforms, which I guess is much more difficult to crawl and clean up.
Peanuts compared to the discourse available on the internet.
The literature that survived thousands of years are cream of the crop; you won't find lots of random unimportant dialog between people thousands of years ago, but you find that on Reddit.
Given premodern population sizes and literacy rates, historical texts probably don't exist in anything like the quantity that internet posts do. Even if they did, the information may not be relevant to the modern world.
There's only ONE* Chinese speaking country, at least if you only count those that have a Chinese speaking majority population, or uses Chinese as the official language.
Singapore has a pretty good relationship with China (with all Chinas, actually). And we have plenty of Chinese speakers, too. I'm not sure how prevalent Baidu is, however.
Honest question, what kind of requests are you thinking of? In my projects I’m always fetching or changing data in a database on each request and if I’m not then I’m probably moving that logic to the frontend.
A basic example is some compute service, say image transformation. You just run computations where all the input is in the request, and all the output goes to the response.
I feel like you still need to the DB for that, for auth at a minimum (which might not need to hit your main DB I guess) if not for logging (spend credit/record usage/just analytics). I guess all of that could be skipped with something like a JWT and log ETL process.
I'm intrigued by edge computing but the DB always seems like the bottleneck so thank you for the example.
