Performance and resource modeling in highly-concurrent OLTP workloads
Barzan Mozafari, Carlo Curino, Alekh Jindal, Samuel R. Madden · 2013
Database administrators of Online Transaction Processing (OLTP) systems constantly face difficult questions. For example, "What is the maximum throughput I can sustain with my current hardware?", "How much disk I/O will my system perform if the requests per second double?", or "What will happen if the ratio of transactions in my system changes?". Resource prediction and performance analysis are both vital and difficult in this setting. Here the challenge is due to high degrees of concurrency, competition for resources, and complex interactions between transactions, all of which non-linearly impact performance.
