Shaman: A Self-Healing Database System

A self-healing system is a grand-challenge vision where the system will detect, diagnose, and repair performance problems and hardware/software faults automatically. These systems take humans out of the failure-recovery loop, enabling recovery to happen at fast machine timescales rather than slower human timescales. Are self-healing database systems Utopia or just a hard puzzle to solve? We argue for the latter and propose to demonstrate a self-healing database system, called Shaman, that is being prototyped at Duke.
