固定速率的ScheduledExecutorService計劃沒有像預期的那樣準確

2022-03-14 08:09:41 資料庫

我有一個 Java 專案(Java 8),應該每 10 毫秒執行一次任務。我使用javaScheduledExecutorService來運行任務:

ScheduledExecutorService executorService = Executors.newSingleThreadScheduledExecutor();
executorService.scheduleAtFixedRate(new QueueTask(), 0, 10, TimeUnit.MILLISECONDS);

從佇列中QueueTask擴展Runnable和輪詢 - 不超過 10 毫秒。每次運行QueueTask我都會記錄“已啟動的 QueueTask”。

根據日志,出于某種原因,任務以相同的毫秒運行,我不明白為什么。例如:

2022-03-09 15:24:32.362 INFO 12536 --- [pool-1-thread-1] com.example.consumer.QueueTask      : started QueueTask, uuid: 40bf7e61-66f3-4869-b5f8-43b9cac8e203, nanoTime: 311179321467600
2022-03-09 15:24:32.362 INFO 12536 --- [pool-1-thread-1] com.example.consumer.QueueTask      : started QueueTask, uuid: a63b814f-2016-4b1a-b17b-d870e4b38c64, nanoTime: 311179322025300
2022-03-09 15:24:32.362 INFO 12536 --- [pool-1-thread-1] com.example.consumer.QueueTask      : started QueueTask, uuid: 17879b1f-96ed-4236-9902-ff98fc772b5a, nanoTime: 311179322376100

我不明白這是怎么回事。我有一個執行緒計劃每 10 毫秒運行一次,有時它以相同的毫秒運行。順便說一句,它并不是每 10 毫秒運行一次,據我了解,調度程式不可能 100% 準確,但它不應該以這種方式運行。我還嘗試在執行緒池中使用多個執行緒,但沒有幫助。

您可以看到列印的納秒System.nanoTime()在日志之間是不同的,但是第一個和第二個日志之間的區別是:350800納秒,即0.3508毫秒。所以這意味著任務沒有間隔 10 毫秒運行。

請注意,executorService.scheduleAtFixedRate()正如 Java 檔案中所提到的,會將任務提交給執行緒,這并不意味著執行緒會在給定的時間內準確地執行任務。

另外你不能保證任務的執行時間,第一個任務可能超過 10 毫秒,然后小于 10 毫秒。

所以你每10毫秒就會有一個新任務提交給你的單執行緒,這些任務的執行時間是不固定的,可能大于或小于10毫秒,所以任務池中的任務數量會更多比執行的任務和您的執行緒將嘗試列印所有這些任務,這就是為什么您看到它在那里同時列印的原因。不能保證輸出,你不能指望它,它也取決于你的機器和你的執行緒調度程式。

固定速率的 ScheduledExecutorService 計劃沒有像預期的那樣準確

該方法的Java檔案scheduleAtFixedRate

提交在給定初始延遲后首先啟用的周期性操作,隨后在給定周期內啟用;也就是說,執行將在 initialDelay 之后開始,然后是 initialDelay period,然后是 initialDelay 2 * period,依此類推。

短跑彌補長跑

我構建了一些代碼來試驗調度。

我所看到的是一些運行時間太短(低于 10 毫秒)以彌補一些運行時間過長(超過 10 毫秒)的運行。

對于我運行的每 100 次迭代,我得到大約一半不到 10 毫秒,大約一半超過 10 毫秒,總平均值非常接近 10 毫秒。例如,如果 100 次迭代中有 47 次運行時間較長,那么 53 次運行時間較短。如果 46 長,則 54 短,依此類推。仔細閱讀結果資料時,似乎長短期運行是交錯的。

鑒于ScheduledExecutorService#scheduleAtFixedRate . 如果您要求增量為 10 毫秒,則服務會努力滿足自開始以來每 10 毫秒的目標,而不是自上次迭代完成后的 10 毫秒。這種努力涉及通過縮短其他時間來補償長期運行。

但也許我錯了。我的代碼可能有問題,或者我的推理有問題。請根據需要糾正我。
