Apache Flink闻名已久,一直没有亲自尝试一把,这两天看了文档,发现在real-time streaming方面,Flink提供了更多高阶的实用函数. 用Apache Flink实现WordCount 下载Apache Flink 0.10.1 启动local模式 bin/start-local.sh 运行scala-shell bin/start-scala-shell.sh remote localhost 6123 Flink中JobManager的默认监听端口是6123 word…

Where did we come from? With the 0.9.0-milestone1 release, Apache Flink added an API to process relational data with SQL-like expressions called the Table API. The central concept of this API is a Table, a structured data set or stream on which relat…

Flink 剖析 1.概述 在如今数据爆炸的时代,企业的数据量与日俱增,大数据产品层出不穷.今天给大家分享一款产品—— Apache Flink,目前,已是 Apache 顶级项目之一.那么,接下来,笔者为大家介绍Flink 的相关内容. 2.内容 2.1 What's Flink Apache Flink 是一个面向分布式数据流处理和批量数据处理的开源计算平台,它能够基于同一个Flink运行时(Flink Runtime),提供支持流处理和批处理两种类型应用的功能.现有的开源计算方案,会把流处…

Apache Flink:十分可靠,一分不差 Apache Flink 的提出背景 我们先从较高的抽象层次上总结当前数据处理方面主要遇到的数据集类型(types of datasets)以及在处理数据时可供选择的处理模型(execution models),这两者经常被混淆,但实际上是不同的概念 数据集的类型 当前数据处理主要遇到的数据集类型可分为两大类,①Unbounded,无限的数据集,体现为快速持续到达的流式数据 ②Bounded,有限的数据集,通常不可改变,即不会发生更新的数据集 传统数…

Apache Flink 的数据流编程模型 抽象层次 Flink 为开发流式应用和批式应用设计了不同的抽象层次 状态化的流 抽象层次的最底层是状态化的流,它通过 ProcessFunction 嵌入到 DataStream API 中,允许用户自由地处理来自一个或多个流的事件(event)以及使用一致的容错状态 此外,用户可以注册事件时间并处理时间回调(callback),这使得程序可以处理更复杂的计算 核心 API 大多数情况下用户不直接在上面描述的这种低的抽象层面上编程,取而代之的是使用所谓…
