Speaker: Goetz Graefe, Google, Inc.

Abstract: 

False conflicts have given locking and serializability a reputation for poor concurrency, poor scalability, and poor system performance. Causes include unnecessarily coarse lock scopes, excessive lock durations, and simplistic lock modes. This talk surveys three published techniques that aim to address these false conflicts.
