Abstract:
This paper presents a transaction model for grid and a grid timestamp concurrency control (GTCC) protocol supporting this model. The GTCC extends the transaction type and lessens the range of transaction conflict to avoid a large number of transaction restart and increase transaction concurrency degree. The correctness of GTCC protocol is proved, and experiment results in a prototype system show that the protocol is feasible and effective.

摘要: 定义了一个网格事务模型,提出了支持该网格事务模型的、基于时标的并发控制协议,证明了协议的正确性。该协议扩充了事务类型,减小了事务的冲突范围,从而避免了大量不必要的事务重启,提高了事务的并发度。性能实验分析表明,该协议是可行且有效的。
