sets in graph transactions.  ...  In addition, we propose a new MV-OCC implementation with two optimizations to address the issue of large read/write sets in graph transactions.  ...  Our MV-OCC follows a general procedure of OCC but combines with our multi-version-based commit/abort rules.  ...

2010 International Journal of Adaptive, Resilient and Autonomic Systems  
Distributed systems with a centralized architecture present the well known problems of single point of failure and single point of congestion. Therefore, they do not scale.  ...  We present a decentralized system built with a structured overlay network which is self-organized and self-healing, providing a transactional replicated storage for small or large scale systems.  ...  As there is no read-phase, it is important that the decision is transmitted to the TPs and rTMs together with the new state of the item, and not only a commit/abort message.  ...

MDCC

Tim Kraska, Gene Pang, Michael J. Franklin, Samuel Madden, Alan Fekete
2013 Proceedings of the 8th ACM European Conference on Computer Systems - EuroSys '13  
Replicating data across multiple data centers allows using data closer to the client, reducing latency for applications, and increases the availability in the event of a data center failure.  ...  Our experiments show that MDCC outperforms existing synchronous transactional replication protocols, such as Megastore, by requiring only a single message round-trip in the normal operational case independent  ...  Acknowledgments We would like to thank the anonymous reviewers and our shepherd, Robbert van Renesse, for all the helpful comments and suggestions.  ...

ParTAC: A Partition-Tolerant Atomic Commit Protocol for MANETs

Brahim Ayari, Abdelmajid Khelil, Neeraj Suri
2010 2010 Eleventh International Conference on Mobile Data Management  
ParTAC is evaluated using simulations to demonstrate the performance of the protocol in terms of commit rate, message efficiency and Commit/Abort decision time.  ...  The support of distributed atomic transactions in mobile ad-hoc networks (MANET) is a key requirement for many mobile application scenarios.  ...  Our analysis shows that ParTAC reduces the Commit/Abort decision time of initiated transactions and helps in trading-off the desired level of the availability, latency and efficiency of the transactional  ...

Towards scalable real-time analytics

Anil K. Goel, Wolfgang Lehner, Jeffrey Pound, Nathan Auch, Peter Bumbulis, Scott MacLean, Franz Färber, Francis Gropengiesser, Christian Mathis, Thomas Bodner
2015 Proceedings of the VLDB Endowment  
We present an overview of our work on the SAP HANA Scale-out Extension, a novel distributed database architecture designed to support large scale analytics over realtime data.  ...  We advocate the decoupling of core database components such as query processing, concurrency control, and persistence, a design choice made possible by advances in highthroughput low-latency networks and  ...  Acknowledgements We would like to thank the HANA Research and Development team for their incredible ongoing efforts.  ...

Hyder - A Transactional Record Manager for Shared Flash

Philip A. Bernstein, Colin W. Reid, Sudipto Das
2011 Conference on Innovative Data Systems Research  
Each transaction executes on a snapshot, logs its updates in one record, and broadcasts the log record to all servers.  ...  Each server rolls forward the log against its locally-cached partial-copy of the last committed state, using optimistic concurrency control to determine whether each transaction commits.  ...  We also thank our collaborators on the meld implementation, Ming Wu and Xinhao Yuan, and on the log implementation, Mahesh Balakrishnan, Dahlia Malkhi, and Vijayan Prabhakaran.  ...

Transactional Failure Recovery for a Distributed Key-Value Store [chapter]

Muhammad Yousuf Ahmad, Bettina Kemme, Ivan Brondino, Marta Patiño-Martínez, Ricardo Jiménez-Peris
2013 Lecture Notes in Computer Science  
In particular, if the transaction manager provides durability (e.g., through logging), then we can relax durability constraints in the key-value store.  ...  With the advent of cloud computing, many applications have embraced the ensuing paradigm shift towards modern distributed keyvalue data stores, like HBase, in order to benefit from the elastic scal ability  ...  This research has been partially funded by the Minist`ere de l'Enseignement sup´erieur, de la Recherche, de la Science et de la  ...

Beyond 1-Safety and 2-Safety for Replicated Databases: Group-Safety [chapter]

Matthias Wiesmann, André Schiper
2004 Lecture Notes in Computer Science  
In this paper, we study the safety guarantees of group communication-based database replication techniques.  ...  Experimental results show the gain of efficiency of group-safety over lazy replication, which ensures only 1-safety.  ...  The main difference with Figure 2 is the response to the client, which is sent back as soon as the transactions is delivered by the atomic broadcast and the decision to commit/abort the transaction is  ...

The case for determinism in database systems

Alexander Thomson, Daniel J. Abadi
2010 Proceedings of the VLDB Endowment  
Further, our system eliminates the requirement for two-phase commit for any kind of distributed transaction, even across multiple nodes within the same replica.  ...  Due to the nondeterminism inherent in traditional concurrency control schemes, however, special care must be taken to ensure that replicas don't diverge.  ...  In order to satisfy ACID's guarantees, distributed transactions generally use a distributed commit protocol, typically two-phase commit, in order to gather the commit/abort decisions of all participating  ...
