------------------------------------
(Warning: Need citation)
I'm newbie to Storm Project, but I can find usage from "setup-ticks!" in
executor.clj.
{code}
(defn setup-ticks! [worker executor-data]
(let [storm-conf (:storm-conf executor-data)
tick-time-secs (storm-conf TOPOLOGY-TICK-TUPLE-FREQ-SECS)
receive-queue (:receive-queue executor-data)
context (:worker-context executor-data)]
(when tick-time-secs
(if (or (system-id? (:component-id executor-data))
(and (not (storm-conf TOPOLOGY-ENABLE-MESSAGE-TIMEOUTS))
(= :spout (:type executor-data))))
(log-message "Timeouts disabled for executor " (:component-id
executor-data) ":" (:executor-id executor-data))
(schedule-recurring
(:user-timer worker)
tick-time-secs
tick-time-secs
(fn []
(disruptor/publish
receive-queue
[[nil (TupleImpl. context [tick-time-secs]
Constants/SYSTEM_TASK_ID Constants/SYSTEM_TICK_STREAM_ID)]]
)))))))
{code}
If worker is Spout and TOPOLOGY-ENABLE-MESSAGE-TIMEOUTS is disabled, it doesn't
send tick tuple which means it's time to check tuples timeout.
tl;dr. It seems that it's working properly, though I've not tested yet.
