I would not be surprised if the current @Reddit outage was caused by the blackout protest from some of the larger subreddits. I could see the balancing/indexing of those subreddits being fairly bespoke, and now that they’re private it’s wrecking havoc on feed generation/caching
@nateberkopec Way back in the day at Shopify @harrybrundage printed out and taped pages and pages of request logs to the wall. We would go through them to find queries to cache with identity cache. It works!
@geejmasterflex IIRC you could cache=false it but there was still another caching layer in front of the database, specifically for endpoints like products.json
Shopify makes this all look easy but it’s not. The reason the flash platform is so good today because of years of great engineering work by some very smart people, working under a ton of pressure to make commerce better for everyone ™

I had to take time off when another merchant’s sale was botted so heavily that it took an entire Shopify region down and we had to figure out (within a few hours) how to allow them to have their sale without causing another massive disruption.
