Yes, but please know this format is not in any way guaranteed. In other

of statistics, I urge you to look into our protobuf export which has many of
these same metrics.

3 means it was handled by operating system thread 3 within the recursor. The
numbers in square brackets have changed a bit I think, I remember the first
number being our internal query id, which increases all the time.

Wall clock time spent waiting on network responses.

Wall clock time totally spent on this query. totms - netwms is a measure of
how much CPU time was spent internally.
