Extending Causal Consistency to any Object Defined by a Sequential Specification

Achour Mostéfaoui, Matthieu Perrin, Michel Raynal, The Distributed Computing Column by Stefan Schmid


This paper presents a generalization of causal consistency suited to the
family of objects defined by a sequential specification. As causality is captured
by a partial order on the set of operations issued by the processes on
shared objects (concurrent operations are not ordered), it follows that causal
consistency allows different processes to have different views of each object
