English

Fadia A. Elbagir, Ahmed Khalid, Khalid Khanfar
2016 International Journal of Computer Trends and Technology  
The commit processing in a Distributed Real Time Database (DRTDBS) can significantly increase execution time of a transaction.  ...  Therefore, designing a good commit protocol is important for the DRTDBS; the main challenge is the adaptation of standard commit protocol into the real time database system and so, decreasing the number  ...  They proposed modified protocol RL2PC adapted to the distributed real-time transaction commit.  ...

Adaptive Logging for Distributed In-memory Databases [article]

Chang Yao, Divyakant Agrawal, Gang Chen, Beng Chin Ooi, Sai Wu
2015 arXiv   pre-print
The results show that adaptive logging can achieve a 10x boost for recovery and a transaction throughput that is comparable to that of command logging.  ...  In this paper, we first extend the command logging technique to a distributed environment, where all the nodes can perform recovery in parallel.  ...  On the other hand, our proposed adaptive logging has been designed to adapt to the real time variability in workload characteristics.  ...

Adaptive Logging

Chang Yao, Divyakant Agrawal, Gang Chen, Beng Chin Ooi, Sai Wu
2016 Proceedings of the 2016 International Conference on Management of Data - SIGMOD '16  
The results show that adaptive logging can achieve a 10x boost for recovery and a transaction throughput that is comparable to that of command logging.  ...  We show that in a distributed system, the only bottleneck of recovery caused by command logging is the synchronization process that attempts to resolve the data dependency among the transactions.  ...  Acknowledgments We would like to thank Qian Lin for his suggestions that help improved the paper. We also thank the reviewers for their valuable comments.  ...
