Improving performance in a DBaaS environment through the use of resource reservation

摘要: Resource reservation provides a user with the requested resource (usually, CPU, memory, space in disk and bandwidth) at time, allowing to have expected performance defined time interval. In context of databases systems, applications long running queries represent big challenge when there is requirement know approximately how query will take execute. This prediction that might be relevant for several reasons. For instance, by knowing longer than expect execute, can performed, which means reserving more resources order execute this shorter future execution. paper presents an approach conceives advance mechanism DBaaS environment using machine learning techniques. general way, proposal use based on give recommendation regarding cost. paper, we present proposed model, configuration, as well some experiments indicate benefits efficiency from our proposal.
