Causal-consistent rollback in a tuple-based language


Rollback is a fundamental technique for ensuring reliability of systems, allowing one, in case of troubles, to recover a past system state. However, the definition of rollback in a concurrent/distributed scenario is quite tricky. We propose an approach based on the notion of causal-consistent reversibility: any given past action can be undone, provided that all the actions caused by it are undone as well. Given that, we define a rollback as the minimal causal-consistent sequence of backward steps able to undo a given action. We define the semantics of such a rollback operator, and show that it satisfies the above specification. The approach that we present is quite general, but we instantiate it in the case of µKlaim, a formal coordination language based on distributed tuple spaces. We remark that this is the first definition of causal-consistent rollback in a shared-memory setting. We illustrate the use of rollback in µKlaim on a simple, but realistic, application scenario.
