Distributed databases take advantage of replication to bring data close to the client, and to always be available. The primary challenge for such databases is to ensure consistency. The inherent trade-off between consistency, performance, and availability represents a fundamental issue in design of the replicated database serving applications with integrity rules. Recent research provide hybrid consistency models that allow the database supports asynchronous updates by default, but synchronisation is available upon request. To help programmers exploit the hybrid consistency model, we propose a set of useful patterns, proof rules, and tool for proving integrity invariants of applications. The main goal of this talk is to co-design the application and the associated consistency in order to ensure application invariants with minimal consistency requirements.
