Abstract:

A global state of a distributed transaction system is consistent if no transactions are in progress. A global checkpoint is a transaction which must view a globally consistent system state for correct operation. We present an algorithm for adding global checkpoint transactions to an arbitrary distributed transaction system. The algorithm is non-intrusive in the sense that checkpoint transactions do not interfere with ordinary transactions in progress however, the checkpoint transactions still produce meaningful results.
