Designing persistence for real-time distributed object systems [chapter]

Igor Nekrestyanov, Boris Novikov, Ekaterina Pavlova
1998 Lecture Notes in Computer Science  
An implementation of persistent object store for real-time systems with strict processing time constraints is a challenging task, because many traditional database techniques, e.g. transaction management  ...  The major contributions are: use of distributed dynamic hashing to achieve load balancing and tight coupling of transaction and virtual memory management, which allows local scheduling of read-only transactions  ...  The Performance Model Proposed concurrency control algorithm has little overhead, but may potentially result in high rate of transaction aborts (typical for all optimistic algorithms).  ...

TxCache: Transactional cache using byte-addressable non-volatile memories in SSDs

Youyou Lu, Jiwu Shu, Peng Zhu
2014 2014 IEEE Non-Volatile Memory Systems and Applications Symposium (NVMSA)  
Transaction is a common technique to ensure system consistency but incurs high overhead. Recent flash memory techniques enable efficient embedded transaction support inside solid state drives (SSDs).  ...  In this paper, we propose a new embedded transaction mechanism, TxCache, for SSDs with non-volatile disk cache.  ...  First, disk cache size is not as large as main memory, and it might not be able to hold large transactions. Second, cache algorithms in disk cache are different from CPU cache algorithms.  ...

Caetano Sauer, Goetz Graefe, Theo Härder
2018 Proceedings of the VLDB Endowment  
This approach not only provides more efficient recovery with less overhead, but also decouples the management of persistent data from in-memory access paths.  ...  This paper proposes a novel approach for transactional storage and recovery called FineLine.  ...  Acknowledgements We are grateful to Viktor Leis for his valuable feedback and insightful suggestions and to Lucas Lersch for being available to bounce off ideas in many informal discussions.  ...

Avoiding disruptive failovers in transaction processing systems with multiple active nodes

Gong Su, Arun Iyengar
2013 Journal of Parallel and Distributed Computing  
The efficient implementation of our algorithm for ordering transactions is a critically important factor in achieving good performance.  ...  Nodes agree on a total ordering for processing requests with a novel low overhead wait-free algorithm that utilizes a small amount of shared memory accessible to the nodes and a simple compare-and-swap  ...  Average latencies for handling transactions are well below 10 ms. The efficient total ordering algorithm is a critically important factor in achieving this performance.  ...

Efficient logging in non-volatile memory by exploiting coherency protocols

Nachshon Cohen, Michal Friedman, James R. Larus
2017 Proceedings of the ACM on Programming Languages  
We show how to extend the logging protocol to building a persistent set (hash map) that also requires only a single round trip to non-volatile memory for insertion, updating, or deletion.  ...  Writes to NVM, however, pass through a processor's memory system, which can delay and reorder them and can impair the correctness and cost of logging algorithms.  ...  ACKNOWLEDGMENT The authors would like to thank the anonymous reviewers of OOPSLA for their help on improving the paper and particularly Section 2 and Section 4.  ...
