Practical Tutorial for a Streaming Computation Framework Based on Golang | |
《基于Golang的流式计算框架实战教程》 |
KisFlow为业务上游计算层,上层接数仓/其他业务方ODS层、下游接本业务存储数据中心。
层级 | 层级说明 | 包括子模块 |
---|---|---|
流式计算层 | 为KisFlow上游计算层,直接对接业务存储及数仓ODS层,如上游可以为Mysql Binlog、日志、接口数据等,为被动消费模式,提供KisFlow实时计算能力。 | KisFlow:分布式批量消费者,一个KisFlow是由多个KisFunction组合。 KisConnectors:计算数据流流中间状态持久存储及连接器。 KisFunctions:支持算子表达式拼接,Connectors集成、策略配置、Stateful Function模式、Slink流式拼接等。 KisConfig: KisFunction的绑定的流处理策略,可以绑定ReSource让Function具有固定的独立流处理能力。 KisSource: 对接ODS的数据源 |
任务调度层 | 定时任务调度及执行器业务逻辑,包括任务调度平台、执行器管理、调度日志及用户管理等。提供KisFlow的定时任务、统计、聚合运算等调度计算能力。 | 任务调度平台可视化:包括任务的运行报表、调度报表、成功比例、任务管理、配置管理、GLUE IDE等可视化管理平台。 执行器管理KisJobs:Golang SDK及计算自定义业务逻辑、执行器的自动注册、任务触发、终止及摘除等。 执行器场景KisScenes: 根据业务划分的逻辑任务集合。 调度日志及用户管理:任务调度日志收集、调度详细、调度流程痕迹等。 |
KisFlow是一种流式概念形态,具体表现的特征如下:
1、一个KisFlow可以由任意KisFunction组成,且KisFlow可以动态的调整长度。
2、一个KisFunction可以随时动态的加入到某个KisFlow中,且KisFlow和KisFlow之间的关系可以通过KisFunction的Load和Save节点的加入,进行动态的并流和分流动作。
3、KisFlow在编程行为上,从面向流进行数据业务编程,变成了面向KisFunction的函数单计算逻辑的开发,接近FaaS(Function as a service)体系。
下面是简单的应用场景案例,具体应用单元用例请 参考
