alt Hacker NewsThanks for offering. In the graph labeled "Prod customer throughput: (higher is better)" eyeballing it within a week you are seeing ~2k qps peak increase over the previous week.
Operationally, how do you handle landing that large of a perf improvement? If my data store changed that much in a week it could break something.
Generally the more throughput the system supports the better. In this case we were hitting limits (btw each operation is many queries of different sizes) and the customer observed higher latencies which is typical if the system can't sustain the throughput required.
After this change latencies are back to normal and throughput increased.
