sdong 9c332aa11a HashLinkList memtable switches a bucket to a skip list to reduce performance outliers ... Summary: In this patch, we enhance HashLinkList memtable to reduce performance outliers when a bucket contains too many entries. We switch to skip list for this case to enable binary search. Add threshold_use_skiplist parameter to determine when a bucket needs to switch to skip list. The new data structure is documented in comments in the codes. Test Plan: make all check set threshold_use_skiplist in several tests Reviewers: yhchiang, haobo, ljin Reviewed By: yhchiang, ljin Subscribers: nkg-, xjin, dhruba, yhchiang, leveldb Differential Revision: https://reviews.facebook.net/D19299		11 years ago
