一文搞懂 Flink 處理 Barrier 全過(guò)程

上次我們講到了 Flink Checkpoint Barrier 全流程 還有 Flink 消費消息的全流程

Flink 處理 Barrier 分兩種：

關(guān)鍵就是 getNextNonBlocked 方法

當沒(méi)有發(fā)生 barrier 對齊完成 這個(gè)動(dòng)作時(shí)，currentBuffered == null，currentBuffered 就是當前要處理的 buffer，當 buffer 是數據的時(shí)候它就正常消費數據走 Flink 消費消息的全流程 ，當遇到 barrier 時(shí)，開(kāi)始處理 barrier

numBarriersReceived 的默認值是0，所以第一個(gè) barrier 進(jìn)來(lái)后，會(huì )進(jìn)入 beginNewAlignment 方法

當再有其他相同的 barrier 進(jìn)入時(shí)，barrierId == currentCheckpointId 為 true，直到 numBarriersReceived + numClosedChannels == totalNumberOfInputChannels 時(shí)，觸發(fā) notifyCheckpoint，并報告 alignment buffer 以及 alignment time。(彩蛋： 稍后會(huì )更新 checkpoint 全流程歡迎關(guān)注 )。

如果其他的 channel 中的 barrier 延遲了，即 numBarriersReceived + numClosedChannels != totalNumberOfInputChannels，已經(jīng) receive barrier 對應的 channel 數據會(huì )進(jìn)入 bufferBlocker。

bufferBlocker 是通過(guò) ArrayDeque currentBuffers 來(lái)存儲數據的，也就是說(shuō)默認情況下 bufferBlocker.currentBuffers 會(huì )無(wú)限增大。

當 numBarriersReceived + numClosedChannels == totalNumberOfInputChannels 時(shí)，會(huì )先進(jìn)行 releaseBlocksAndResetBarriers() 在進(jìn)行 notifyCheckpoint。

releaseBlocksAndResetBarriers 主要的目的是要先消費已加入緩存中的數據。

當執行完 releaseBlocksAndResetBarriers 方法時(shí)，currentBuffered!=null 了，會(huì )進(jìn)入

然后直接消費數據

一直消費緩存中的數據( 此過(guò)程會(huì )阻塞不會(huì )繼續消費 inputGate 中的數據)，直至消耗完成

完成了之后，就跟程序第一次運行至此一樣，循環(huán)往復。
