Adaptable Replicated Objects in Distributed Environments
Résumé
This paper presents an architecture and a run-time support environment for adaptable replicated objects. The architecture separates the type-specific logic of a replicated object, e.g.\ concurrency control, from the generic logic, e.g. consistency management. A replicated object is structured into components with generic interfaces. A programmer can adapt a replicated object to the application specifics by replacing components that implement generic logic. Our architecture, while making the replicated object flexible, does not preclude optimizations based on object semantics or on application specifics. A tool-box of ready-to-use objects reduces development cost for new replicated object types.
