Flink Backward - The Apache Flink Retrospective

前面几篇文章带大家了解了 Flink 是什么、能做什么,本篇将带大家了解 Flink 究竟是如何完成这些的,Flink 本身架构是什么样的,让大家先对 Flink 有整体认知,便于后期理解。一、Flink 组件栈Flink是一个分层架构的系统,每一层所包含的组件都提供了特定的抽象,用来服务于上层组件。Flink分层的组件栈如下图所示:Deployment 层该层主要涉及了Flink的部署模式,Flink支持多种部署模式:本地、集群(Standalone/YARN)云(GCE/EC2)Standalone部署模式与Spark类似。我们看一下Flink on YARN的部署模式,如下图所示:通过上图可以看到,YARN AM 与 Flink JobManager 在同一个 Container 中,这样 AM 可以知道 Flink JobManager 的地址,从而 AM 可以申请 Container 去启动 Flink TaskManager。待 Flink 成功运行在 YARN 集群上,Flink YARN Client 就可以提交 Flink Job 到 Flink JobManager,并进行后续的映射、调度和计算处理。Runtime层Runtime 层提供了支持 Flink 计算的全部核心实现,比如:支持分布式 Stream 处理JobGraph 到 ExecutionGraph 的映射、调度等等,为上层API层提供基础服务。API层API 层主要实现了面向无界 Stream 的流处理和面向 Batch 的批处理 API。其中面向流处理对应 DataStream API,面向批处理对应 DataSet API。Libraries 层该层也可以称为 Flink 应用框架层,根据 API 层的划分,在 API 层之上构建的满足特定应用的实现计算框架,也分别对应于面向流处理和面向批处理两类。面向流处理支持:CEP(复杂事件处理)、基于 SQL-like 的操作(基于 Table 的关系操作);面向批处理支持:FlinkML(机器学习库)、Gelly(图处理)。二、Flink 集群架构主要为 Runtime 层细分。Flink 的通用系统架构如下图所示。用户在客户端提交作业(Job)到服务端。服务端为分布式的主从架构。Dispatcher 服务负责提供 REST 接口来接收 Client 提交的 Job,运行 Web UI,并负责启动和派发 Job 给 JobManager。Resource Manager 负责计算资源(TaskManager)的管理,其调度单位是 slots。JobManager 负责整个集群的任务管理、资源管理、协调应用程序的分布执行,将任务调度到 TaskManager 执行、检查点(checkpoint)的创建等工作。TaskManager(worker)负责 SubTask 的实际执行,提供一定数量的 Slots,Slots 数就是 TM 可以并发执行的task数。当服务端的 JobManager 接收到一个 Job 后,会按照各个算子的并发度将 Job 拆分成多个 SubTask,并分配到 TaskManager 的 Slot 上执行。任务的提交流程如下所示:三、编程模型(API层次结构)主要为 API & Library 层细分。Flink提供了不同层次的接口,方便开发者灵活的开发流处理、批处理应用,根据接口使用的便捷性、表达能力的强弱分为四层:最底层提供了有状态流:可以自定义状态信息和处理逻辑,但是也需要你自己管理状态的生命周期,容错,一致性等问题。核心开发层:包括 DataStream API 和 DataSet API,它们提供了常见的数据转换,分组,聚合,窗口,状态等操作。这个层级的 api 适合大多数的流式和批式处理的场景。声明式 DSL 层:是以表为中心的声明式 DSL,其中表可能会动态变化(在表达流数据时)。Table API 提供了例如 select、project、join、group-by、aggregate 等操作结构化层:SQL API,它是最高层的 api,可以直接使用 SQL 语句进行数据处理,无需编写 Java 或 Scala 代码。这个层级的 api 适合需要快速响应业务需求,缩短上线周期,和自动调优的场景,但也最不灵活和最不具有表现力。四、Flink 数据流图前一篇《WordCount 实现》文章中,我们写了一个入门程序,那么代码中的输入、输出、计算等算子是如何与上面的概念对应起来的呢?程序由多个 DataStream API 组成,这些 API,又被称为算子 (Operator),共同组成了逻辑视角。在实际执行过程中,逻辑视角会被计算引擎翻译成可并行的物理视角。在实际执行过程中,这些 API 或者说这些算子是并行地执行的。分区:在大数据领域,当数据量大到超过单台机器处理能力时,就将一份数据切分到多个分区(pattition)上,每个分区分布在一个虚拟机或物理机。并行:从物理视角上看,每个算子是并行的,一个算子有一个或多个算子子任务(Subtask),每个算子子任务只处理一小部分数据,所有算子子任务共同组成了一个算子。根据算子所做的任务不同,算子子任务的个数可能也不同。独立:算子子任务是相互独立的,一个算子子任务有自己的线程,不同算子子任务可能分布在不同的物理机或虚拟机上。数据交换:直传:source -> map,数据完全传递重分配:map -> keyBy,数据按照一定方式重新分配到多个算子中聚合:keyBy -> sink,多个算子的输出数据合并到一个算子中五、小结本篇文章从 Flink 组件栈开始,介绍 Flink 的分层架构,然后对每一层(Deploment、Runtime、API)进行了细致的讲解,说明每一层的作用和架构。最后对 Flink 数据流图进行了讲解,说明 Flink 代码是如何对应到具体执行的 task 的。通过本篇讲解带大家了解了 Flink 整体架构,对 Flink 工作结构有了一个基础的认知,后面将会对每个 Flink 核心概念和组件进行细致的讲解。参考文章:Flink CookBook—Apach Flink核心知识介绍Flink架构及工作原理介绍 - Workspace of LionHeartFlink 架构 - 官方文档God-Of-BigData/大数据框架学习/Flink核心概念综述.md at master · wangzhiwubigdata/God-Of-BigData
