It is configured with a  spoke count and  resolution¤. Timers may be scheduled arbitrarily far in the future. A timeout thread is spawned to step through the timer wheel and fire expired timers at regular intervals.The  spoke count) determines the size of the timer vector.A larger spoke count will result in less insert contention" at each spoke and will require  more memory to store the timer wheel.A smaller spoke count will result in more insert contention" at each spoke and will require  less memory to store the timer wheel.The  resolution– determines both the duration of time that each spoke corresponds to, and how often the timeout thread wakes. For example, with a resolution of 1s, a timer that expires at 2.5s4 will not fire until the timeout thread wakes at 3s.A larger resolution will result in more insert contention at each spoke,  less accurate timers, and will require  fewer wakeups by the timeout thread.A smaller resolution will result in less insert contention at each spoke,  more accurate timers, and will require  more wakeups by the timeout thread.1The timeout thread has some important properties:fThere is only one, and it fires expired timers synchronously. If your timer actions execute quicky,  N them directly. Otherwise, consider registering an action that enqueues the real) action to be performed on a job queue.*Synchronous exceptions thrown by enqueued IOW actions will bring the thread down, which will cause it to asynchronously throw a  exception to the thread that  …d it. If you want to catch exceptions and log them, for example, you will have to bake this into the registered actions yourself.+Below is a depiction of a timer wheel with 6 timers inserted across 8 spokes, and a resolution of 0.1s.
