S3: A Scalable In-memory Skip-List Index for Key-Value Store
Summary: S3 is a RocksDB-compatible, scalable in-memory skip list designed for variable-sized data and efficient disk flushing. Its cache-sensitive guard layer, semi-ordered concurrent skip list, and workload-aware neural guard selection deliver fast lookup/range queries at scale. (summarized by gpt-5.6-luna on Jul 24 2026)
