问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . What is the benefit of using Windows Workflow foundation (WF) versus rolling your own workflow framework? From what I can tell, WF only provides a pretty bare-bones runtime engine, a bunch of classes, and a schema (XAML-based) for defining workflows. All the hard stuff such

问题 Problem Is there any way in Airflow to create a workflow such that the number of tasks B.* is unknown until completion of Task A? I have looked at subdags but it looks like it can only work with a static set of tasks that have to be determined at Dag creation. Would dag triggers work? And if so could you please provide an example. I have an issue where it is impossible to know the number of task B's that will be needed to calculate Task C until Task A has been completed. Each Task B.* will

WorkFlow 工作流

阅读更多关于 WorkFlow 工作流

工作流工作流（Workflow），指“业务过程的部分或整体在计算机应用环境下的自动化”。是对工作流程及其各操作步骤之间业务规则的抽象、概括描述。工作流解决的主要问题是：为了实现某个业务目标，利用计算机软件在多个参与者之间按某种预定规则自动传递文档、信息或者任务。一个完整的数据分析系统通常都是由多个前后依赖的模块组合构成的：数据采集、数据预处理、数据分析、数据展示等。各个模块单元之间存在时间先后依赖关系，且存在着周期性重复。为了很好地组织起这样的复杂执行计划，需要一个工作流调度系统来调度执行。工作流调度实现方式简单的任务调度：直接使用linux的crontab来定义,但是缺点也是比较明显，无法设置依赖。复杂的任务调度：自主开发调度平台，使用开源调度系统，比如azkaban、Apache Oozie、Cascading、Hamake等。其中知名度比较高的是Apache Oozie，但是其配置工作流的过程是编写大量的XML配置，而且代码复杂度比较高，不易于二次开发。工作流调度工具之间对比下面的表格对四种hadoop工作流调度器的关键特性进行了比较，尽管这些工作流调度器能够解决的需求场景基本一致，但在设计理念，目标用户，应用场景等方面还是存在显著的区别，在做技术选型的时候，可以提供参考。特性 Hamake Oozie Azkaban Cascading

问题 I've an API endpoint, /api/create/ . This creates a new entry in the DB depending upon the payload received from the client.

问题 Bob, Ben and Mike are working on an awesome project. Bob has created a local branch named foo. Bob will share branch foo with Ben, so Ben can pull and push to it. Bob don't want show this branch to Mike. Bob don't want push this branch to origin. What is the simplest setup for such scenario ? 回答1: The easiest way to manage authorization access remains adding an extra layer like Gitolite on your own repo, in order to manage branch access rights. 回答2: If these repositories are on the developers

问题 Can we have any alternative way to make run-able the custom Workflow activity in Workflow steps. All the time what I do is register the dll using Plugin registration tool and then restart the server. Then only we can use the custom workflow activity on Workflow. I have tried after restarting the IIS and hoping so it'll be done but no luck. All the time restarting server should not be any solution. Is there any alternative way for it please suggest. All you are suggestion would be greatly

Schedule workflows via external tool

问题 I've been doing some research into scheduling workflows to run at certain times/dates but I haven't really found anything that does what I need to. I read somewhere that workflows can be created in CRM and then run by a console tool or something by a Windows schedule service. By what I've read it sounds like this would be what I need but I can't find anywhere that tells me how to create one of these or set it up, so I was wondering if anyone would be able to help me with it. Thanks 回答1: A

问题 I have a Windows Service wrapping a WCF Service, which contains a WorkflowApplication, which runs Activities. I have also configured SQL Server 2008 Express (I know, it's approaching EOL, but the documentation explicitly states that only SQL Server 2005 or SQL Server 2008 are supported) to host the database and the connection works . To be even clearer: The entire process of the Activity completes and receives the return (I'm calling it via the WCF client wrapped in PowerShell). The issue
