vagetablechicken commented on issue #3204: usleep() is obsolete, and may be set the wrong interval by integer overflow URL: https://github.com/apache/incubator-doris/issues/3204#issuecomment-604334778 > The usual C++11 std::this_thread::sleep_for is not high resolution sleep. Many people say so. I haven't tested about it. But refer to KUDU, using SleepFor() in monotime.h is a good choice. https://github.com/apache/incubator-doris/blob/9ee1704859c1f890e3993d11ce606c166ac74ba0/be/src/util/monotime.h#L243-L253
