How to Have Your Causality and Wall Clocks Too



Jon Moore talks about distributed monotonic clocks (DMC) whose timestamps can reflect causality but which have a component that stays close to wall clock time. This scheme builds on previous hybrid logical clock proposals by adding important operational hooks and by building in mechanisms to prevent a single runaway system clock from dragging a whole cluster's logical clocks into the future.


Jon Moore is a Senior Fellow at Comcast Cable, where he leads the Core Application Platforms group that focuses on building scalable, performant, robust software components for the company's varied software product development groups. His current interests include distributed systems, fault tolerance, Texas Hold'em, and building healthy and engaging engineering cultures.
