sdong f1b9f804e9 Add a mode to always pick the oldest file to compact for each level ... Summary: Add options.compaction_pri, which specifies the policy about which file to compact first. kCompactionPriByLargestSeq will compact oldest files first. Verified the behavior in db_bench but did not write unit tests yet. Also need to make it settable through option string and dynamically changeable. Test Plan: Will write unit tests Reviewers: igor, rven, anthony, kradhakrishnan, IslamAbdelRahman, yhchiang, MarkCallaghan Reviewed By: yhchiang Subscribers: leveldb, dhruba Differential Revision: https://reviews.facebook.net/D45951		2015-09-21 17:21:59 -07:00
