Twitter created Snowflake many years ago to generate IDs. Unsure whether it’s still in use. https://blog.twitter.com/engineering/en_us/a/2010/announcing-snowfl

  That sounds nice and simple, and fits in 64 bits (vs 128): "we settled on a composition of: timestamp, worker number and sequence number. Sequence numbers are per-thread and worker numbers are chosen at startup via zookeeper"

  Twitter uses strings instead of ints to represent the 64 bit UID, because Javascript only supports 53bit ints instead of 64bit... https://developer.twitter.com/en/docs/twitter-ids https://developer.twitter.com/en/docs/twitter-ids
