Said on Postgres FM

“I was surprised that there's a threshold. And once I saw the threshold, it makes sense to warn people. You test this in your own little environment, not thinking twice about growth. … Once UUID 4 is running for a while and the index size is growing, once it just consumes all the memory, it kicks the table out of memory.” — Kirk Wolak, Postgres FM

“I like Aurora because they charge you for IO, and your work on query performance optimization can be measured in dollars. … If it affects this particular index, UUID version 4 will cost you roughly 10 times more than UUID version 7 in terms of IO costs on Aurora. It's not a measurement, it's prediction.” — Nikolay Samokhvalov, Postgres FM
