Long time coming, but going to properly shut down discove.xyz Jan 1st; any remaining users, export your data/feed algo code that you want to keep. It costs too much to run & maintain, given nr of custom feeds it caches and given its hosted on vercel. Might relaunch at some point/could open source if enough interest

discove: - custom feeds can take up to 2 mins to run on SQL, can't let first user going to that feed in that time period get an uncached version, or they wait for 2 mins for the page to load. That's what just cloudflare edge cache would do - cache is stale (expires) in less than 5 mins (as chrono/algo social feeds are)

=> discove caches to redis the first 3 pages of results for all custom feeds every 5 mins, hundreds of user created custom SQL feeds, some queries take 30s to 2 mins to run. Just a Cloudflare edge cache would result in a significant percentage of users having to wait the entire duration of the SQL exec to render page

almost looks like you're subsidizing inefficient sql written by no-coders to the tune of 2k a month. that's 👀 about how easy it is to write expensive queries
