Implementations Based Evaluation of No-Wait Approach for Resolving Conflicts in Databases

Abstract

In this paper, we describe No-Wait concurrency control mechanisms to address conflict resolution and then comprehensively evaluate their performance under Read-Committed and Serializability isolation levels using an in-memory database system in various configurations and contention scenarios. Key performance metrics are percentage of transaction aborts and average latency for those who do not abort. Our evaluations affirm that the No-Wait approach indeed offers a cost-effective, practical alternative to traditional conflict resolution mechanisms.
