Pop open the network pane in the browser tools and try running this SQL query for a demo of how clever this is:

    select country_code, long_name from wdi_country
    order by rowid desc limit 100

It fetches just 54.2KB of new data (across 49 small HTTP requests) to return 100 results - from a statically hosted database file that's 668.8MB!

I have an animated GIF demo of this here: https://twitter.com/simonw/status/1388933800445452290
