How count-min sketches work – frequencies, but without the actual data

Nice setup with the Wodehouse. There are lesser-used sketches beyond the basic Bloom, HyperLogLog, and count-min. Maybe for another article.
stopachka•3mo ago
Thank you! Are there are particular data structures that you think I should look into?
esafak•3mo ago
Cuckoo, XOR, ribbon, and counting Bloom filters.
stopachka•3mo ago
Thank you, I'll dive deeper.
pshirshov•3mo ago
Hyperminhash!

Cool! How did you do the reactive demos on the site? I assume it was with instantDB? How hard was it to integrate into a blog post?
stopachka•3mo ago
Thank you!

Since all the reactive demos are local, I didn't add Instant in this case.

One little trick I did for data was here:

https://github.com/instantdb/instant/blob/main/client/www/co...

Mainly: I wanted to get all counts for Wodehouse, but didn't want to block the page load for that. So what I did was take a small subset of the data that's needed to render the page, and have that written into the file. Then after load I fetch all the other counts.

In the tutorial I also used Bun.xxHash3, but to make sketches run on the client, I had to replace that with a library.

The actual sketch implementation that backs the demos is here:
