sdong 7842920be5 Slow down writes by bytes written ... Summary: We slow down data into the database to the rate of options.delayed_write_rate (a new option) with this patch. The thread synchronization approach I take is to still synchronize write controller by DB mutex and GetDelay() is inside DB mutex. Try to minimize the frequency of getting time in GetDelay(). I verified it through db_bench and it seems to work hard_rate_limit is deprecated. options.delayed_write_rate is still not dynamically changeable. Need to work on it as a follow-up. Test Plan: Add new unit tests in db_test Reviewers: yhchiang, rven, kradhakrishnan, anthony, MarkCallaghan, igor Reviewed By: igor Subscribers: ikabiljo, leveldb, dhruba Differential Revision: https://reviews.facebook.net/D36351		10 years ago
