实时计算 Flink版流处理迭代的相关内容

Flink流处理之迭代案例

当前Flink将迭代的重心集中在批处理上，之前我们谈及了批量迭代和增量迭代主要是针对批处理（DataSet）API而言的，并且Flink为批处理中的迭代提供了针对性的优化。但是对于流处理（DataStream），Flink同样提供了对迭代的支持，这一节我们主要来分析流处理中的迭代，我们将会看到流处理...

Flink流处理迭代之化解反馈环

我们都知道Flink在可迭代的流处理中引入了反馈边来将本次迭代的结果反馈给迭代头以进行下一次迭代，这在执行拓扑中引入了环（反馈环）。Flink主要应对的执行拓扑还是有向无环图（DAG），最终它选择了将反馈环进行化解使其能够适配有向无环图的结构，而如何对反馈环进行化解是我们这一篇主要探讨的话题。任何...

Flink流处理之迭代API分析

IterativeStream Flink在DataStream中也是通过一个特定的可迭代的流（IterativeStream）来构建相关的迭代处理逻辑，这一点跟DataSet提供的可迭代的数据集（IterativeDataSet）的是类似的。 IterativeStream继承自DataStrea...

Flink流处理之迭代任务

前面我们分析过Flink对迭代在流图中的特殊处理，使得迭代中的反馈环得以转化为普通的DAG模型。这一篇我们将剖析运行时的流处理迭代任务的执行机制。这里涉及到两个任务类： StreamIterationHead：迭代头任务，它借助于反馈阻塞队列从迭代尾部接收参与下一次迭代的反馈数据。 StreamIt...
