Summary: In internal stats, remember read latency histogram, if statistics is enabled. It can be retrieved from DB::GetProperty() with "rocksdb.dbstats" property, if it is enabled. Test Plan: Manually run db_bench and prints out "rocksdb.dbstats" by hand and make sure it prints out as expected Reviewers: igor, IslamAbdelRahman, rven, kradhakrishnan, anthony, yhchiang Reviewed By: yhchiang Subscribers: MarkCallaghan, leveldb, dhruba Differential Revision: https://reviews.facebook.net/D44193
