public class ThrottleSpecManager
extends BaseTable

This class manages the "throttlespec" table, which contains the throttle specifications for each connection. These are basically tuples consisting of a regexp and a fetch rate. There's a description of each tuple, so that a person can attach a description of what they are attempting to do with each limit.
