Ulepszony dwufazowy protokół do zarządzania transakcjami w czasie rzeczywistym

Abstrakty
Based on the existing two-phase commit protocol (2PC), this paper proposes a protocol adapted to the distributed real-time transaction commit, which can avoid the blocking problem when dealing with transactions by coordinator redundancy; additionally, by the "health loan" of the locked data, the concurrency of transaction implementation is expanded to save the waiting time. Experimental analysis shows that: when the average arrival interval time of transaction is small, the success rate of the improved commit protocol is significantly higher than that of 2PC.
artykule zaproponowano protokół bazujący na dwufazowym protokole typu 2PC. Nowy protokół pozwala na oszczędność czasu oczekiwania – jeśli średni czas odstępu między transakcjami jest mały przepływność danych jest wyższa niż w klasycznym protokole 2PC.
