2. The computer-implemented method of claim 1 , wherein the identifying one or more spikes comprises: determining an instantaneous velocity of each query request from the query stream for a particular parameter, calculated as an inverse of a difference in time between an instant query request and a most recent query request for the particular parameter; calculating an updated weighted average velocity from a combination of a previous weighted average velocity and a weighted instantaneous velocity for the particular parameter; calculating an instantaneous acceleration of each query request for the particular parameter as a difference between the updated weighted average velocity and the previous weighted average velocity, per the difference in time between an instant query request and a most recent query request; and determining an updated weighted average acceleration from a combination of a previous weighted average acceleration and a weighted instantaneous acceleration for the particular parameter.
