Performance Modeling and Analysis of a Database Server with Write-Heavy Workload
Publikation/Tidskrift/Serie: [Host publication title missing]
Resource-optimization of the infrastructure for service oriented applications require accurate performance models. In this paper we investigate the performance dynamics of a MySQL/InnoDB database server with write-heavy workload. The main objective of our investigation was to understand the system dynamics due to the buffering of disk operations that occurs in database servers with write-heavy workload. In the paper, we characterize the traffic and its periodic anomalies caused by flushing of the buffer. Further, we present a performance model for the response time of the requests and show how this model can be configured to fit with actual database measurements. Also, we show that window-based admission control outperforms rate-based admission control for these types of systems.
