>> The above query should do 10-20 GET requests, fetching a total of 130 - 270KiB, depending on if you ran the above demos as well. Note that it only has to do 20 requests and not 270 (as would be expected when fetching 270 KiB with 1 KiB at a time). That’s because I implemented a pre-fetching system that tries to detect access patterns through three separate virtual read heads and exponentially increases the request size for sequential reads. This means that index scans or table scans reading more than a few KiB of data will only cause a number of requests that is logarithmic in the total byte length of the scan. You can see the effect of this by looking at the “Access pattern” column in the page read log above.
>> Sqltorrent is a custom VFS for sqlite which allows applications to query an sqlite database contained within a torrent. Queries can be processed immediately after the database has been opened, even though the database file is still being downloaded. Pieces of the file which are required to complete a query are prioritized so that queries complete reasonably quickly even if only a small fraction of the whole database has been downloaded.
>> […] Creating torrents: Sqltorrent currently only supports torrents containing a single sqlite database file. For efficiency the piece size of the torrent should be kept fairly small, around 32KB. It is also recommended to set the page size equal to the piece size when creating the sqlite database
Would BitTorrent be faster over HTTP/3 (UDP) or is that already a thing for web seeding?

Hadn't seen wilsonzlin/edgesearch, thx:
