#ifndef MYSQL_SERVICE_THD_WAIT_INCLUDED
#define MYSQL_SERVICE_THD_WAIT_INCLUDED
/**
@file include/mysql/service_thd_wait.h
This service provides functions for plugins and storage engines to report
when they are going to sleep/stall.
SYNOPSIS
thd_wait_begin() - call just before a wait begins
thd Thread object
Use NULL if the thd is NOT known.
wait_type Type of wait
1 -- short wait (e.g. for mutex)
2 -- medium wait (e.g. for disk io)
3 -- large wait (e.g. for locked row/table)
NOTES
This is used by the threadpool to have better knowledge of which
threads that currently are actively running on CPUs. When a thread
reports that it's going to sleep/stall, the threadpool scheduler is
free to start another thread in the pool most likely. The expected wait
time is simply an indication of how long the wait is expected to
become, the real wait time could be very different.
thd_wait_end() called immediately after the wait is complete
thd_wait_end() MUST be called if thd_wait_begin() was called.
Using thd_wait_...() service is optional but recommended. Using it will
improve performance as the thread pool will be more active at managing the
thread workload.
