Method Detail

update

void update(long duration,
            TimeUnit unit)

Adds a recorded duration. It's basically the same as using time() and then stop(). Hereby we can update the time duration by calling just one method. This is used to log the time span of each of the phase during query execution in Pinot.

Parameters:

duration - the length of the duration

unit - the scale unit of duration

getTimer

Object getTimer()

Returns the actual object of timer.
