Towards Taming the Adaptivity Problem

Systems following the Polyglot Persistence paradigm are on the rise and with them come new problems and challenges. A major challenge is the ability to automatically self-adapt to changing requirements and workloads. The most difficult and as yet rarely discussed form of adaptivity relates to cahanges to the underlying data composition and topology. The search for a topology suited best for a given set of requirements can be modelled as a complex optimization problem.
