POST /v1/keys no longer slows down or returns 502 keys_unavailable in accounts with many keys
In an account holding tens of thousands of keys, creating a key could take 15 seconds or more and return 502 keys_unavailable, and other requests in the account waited while it ran. Creating a key now reads only the chain of keys that made the calling key and the keys under a maker with a daily limit, and completes in under 100 ms in an account with 50,000 keys.
Same day.
