not adapt naturally to workload characteristics and patterns in query execution plans.  ...  In this paper, we argue that deep learning can be applied to the query performance prediction problem, and we introduce a novel neural network architecture for the task: a plan-structured neural network  ...  For example, the neural network architecture presented here could be adapted to handle a dynamic number of concurrent queries. Doing so would require modeling the resource contention among queries.  ...
