Efficient Distributed Transaction Processing in Heterogeneous Networks

Proceedings of the VLDB Endowment, 2023
Countrywide and worldwide business, like gaming and social networks, drives the popularity of inter-data-center transactions. To support inter-data-center transaction processing and data center fault tolerance simultaneously, existing protocols suffer ...

FLUID: Towards Efficient Continuous Transaction Processing in DAG-Based Blockchains

IEEE Transactions on Knowledge and Data Engineering, 2023
In most blockchain-based application scenarios, a complete application logic consists of multiple continuous transactions, in which the initiation of one transaction depends on the confirmation result of the previous one.

Nezha: Exploiting Concurrency for Transaction Processing in DAG-based Blockchains

IEEE International Conference on Distributed Computing Systems, 2022
A Directed Acyclic Graph (DAG)-based blockchain with its inherent parallel structure can potentially significantly improve the throughput performance over conventional blockchains. Such a performance improvement can be further enhanced through concurrent

A Reputation-Based Mechanism for Transaction Processing in Blockchain Systems

IEEE transactions on computers, 2022
Blockchain protocols require nodes to verify all received transactions before forwarding them. However, massive spam transactions cause the participants in blockchain systems to consume many resources in verifying and propagating transactions. This paper

Graph Transactions as Processes [PDF]

, 2006
Transactional graph transformation systems (t-gtss) have been recently proposed as a mild extension of the standard dpo approach to graph transformation, equipping it with a suitable notion of atomic execution for computations. A typing mechanism induces a distinction between stable and unstable items, and a transaction is defined as a shift ...

Carousel: Low-Latency Transaction Processing for Globally-Distributed Data

SIGMOD Conference, 2018
The trend towards global applications and services has created an increasing demand for transaction processing on globally-distributed data. Many database systems, such as Spanner and CockroachDB, support distributed transactions but require a large ...

Fast in-memory transaction processing using RDMA and HTM

Symposium on Operating Systems Principles, 2015
We present DrTM, a fast in-memory transaction processing system that exploits advanced hardware features (i.e., RDMA and HTM) to improve latency and throughput by over one order of magnitude compared to state-of-the-art distributed transaction systems ...

Communicating transaction processes

Third International Conference on Application of Concurrency to System Design, 2003. Proceedings., 2004
Message sequence charts (MSC) have been traditionally used to depict execution scenarios in the early stages of design cycle. MSCs portray inter-process (inter-object) interactions. Synthesizing intra-process (intra-object) executable specifications from an MSC-based description is a nontrivial task.

Balanced task allocation in the on‐demand computing‐based transaction processing system using social spider optimization

Concurrency and Computation, 2017
Balanced task allocation is one of the methods that can be used to maximize the performance and reliability in the on‐demand computing‐based transaction processing system. On‐demand computing is an increasingly popular enterprise model.
