TransEdge：支持跨不可信边缘节点的高效读操作
TransEdge: Supporting Efficient Read Queries Across Untrusted Edge Nodes
摘要：
我们提出了一种用于边缘计算系统等不可信环境的分布式事务处理系统TransEdge。TransEdge的与众不同之处在于它专注于对只读事务的有效支持。TransEdge允许在大多数情况下使用一轮一致地从不同分区读取，在最坏的情况下不超过两轮。TransEdge的设计围绕着这种依赖性跟踪方案，包括共识和事务处理协议。我们的性能评估表明，与当前拜占庭系统相比，TransEdge的快照只读事务实现了9- 24倍的加速。
英文摘要：
We propose Transactional Edge (TransEdge), a distributed transaction processing system for untrusted environments such as edge computing systems. What distinguishes TransEdge is its focus on efficient support for read-only transactions. TransEdge allows reading from different partitions consistently using one round in most cases and no more than two rounds in the worst case. TransEdge design is centered around this dependency tracking scheme including the consensus and transaction processing protocols. Our performance evaluation shows that TransEdge's snapshot read-only transactions achieve an 9-24x speedup compared to current byzantine systems.
