We upload a set of accumulating timers and counters to track service time for different types of operations, across several dimensions (e.g. did we hit the plan cache, was a remote involved, etc.) Also... Standardize on DiffTime as a standard duration type, and try to use it consistently. See discussion here: https://github.com/hasura/graphql-engine/pull/3584#pullrequestreview-340679369 It should be possible to overwrite that module so the new threadDelay sticks per the pattern in #3705 blocked on #3558 Rename the Control.Concurrent.Extended.threadDelay to `sleep` since a naive use with a literal argument would be very bad! We catch a bug in 'computeTimeDiff'. Add convenient 'Read' instances to the time unit utility types. Make 'Second' a newtype to support this.
