Revision df5eeb85caf76a2f038d4029f95de36b91ee0054 authored by Yi Wu on 13 November 2016, 21:00:52 UTC, committed by Facebook Github Bot on 13 November 2016, 21:09:16 UTC
Summary: Implement a insert hint into skip-list to hint insert position. This is to optimize for the write workload where there are multiple stream of sequential writes. For example, there is a stream of keys of a1, a2, a3... but also b1, b2, b2... Each stream are not neccessary strictly sequential, but can get reorder a little bit. User can specify a prefix extractor and the `SkipListRep` can thus maintan a hint for each of the stream for fast insert into memtable. This is the internal implementation part. See #1419 for the interface part. See inline comments for details.
