Invariant Safety for Distributed Applications

We study a proof methodology for verifying the safety of data invariants of highly-available distributed applications that replicate state. The proof is (1) modular: one can reason about each individual operation separately, and (2) sequential: one can reason about a distributed application as if it were sequential. We automate the methodology and illustrate the use of the tool with a representative example.Comment: Workshop on Principles and Practice of Consistency for Distributed Data (PaPoC), Mar 2019, Dresden, Germany. https://novasys.di.fct.unl.pt/conferences/papoc19
