开源分布式Job系统,调度与业务分离-如何创建周期性的HttpJob任务

由 久未见 提交于 2021-02-20 08:27:51
项目介绍： Hangfire：是一个开源的job调度系统,支持分布式JOB！！ Hangfire.HttpJob 是我针对Hangfire开发的一个组件,该组件和Hangfire本身是独立的。可以独立更新Hangfire版本不影响！ 该组件已被Hangfire官方采纳，在Hangfire官网可以查到： 开源地址： https://github.com/yuzd/Hangfire.HttpJob 该项目目的是： 剥离Job调度和业务 Hangfire.HttpJob究竟是干嘛的 传统使用Hangfire都是把JOb的处理逻辑代码写在和Hangfire的同一个工程！ 缺点： 这样就耦合在了一起，如果业务线增大，会导致每个业务线的Job处理逻辑都得和Hangfire耦合在一起！发布的时候所有业务线Job都得暂停调度 而使用了Hangfire.HttpJob的话 就是把Hangfire的服务拓展成可以把Job的处理逻辑代码写在别的工程里面(以webapi的形式暴露给Hangfire去调度) 优点：这样就解耦了Hangfire和业务处理逻辑，业务job开发者可以忽略Hangfire的存在！不同的业务线分开不同的JobAgent可以分别部署，发布互不影响 Hangfire.HttpJob 是对Hangfire的一个扩展插件，利用Hangfire

Django: Running a process each day at specified user local time

由 感情迁移 提交于 2021-02-19 09:23:17
问题 I'm porting my site to python/django, and one of the main exercises involves a set of data where users can schedule an event in their local time, and have it happen every day. Currently i have a cron job (on another server) that hits up a method every e.g 5 minutes and see's if anything needs to be schedule over the next (let's say ) 10 minutes. I store a Time value, and the user's local timezone for each job What is the best way to do this? Right now I am working on a function that: Converts

How to run queue worker on shared hosting

由 早过忘川 提交于 2021-02-19 02:38:05
问题 My Laravel application has a queued event listener and I have also set up the cronjob to run schedule:run every minute. But I don't know how I can run the php artisan queue:worker command persistently in the background. I found this thread where it was the most voted approach: $schedule->command('queue:work --daemon')->everyMinute()->withoutOverlapping(); However, on a different thread some people complained that the above-mentioned command creates multiple queue worker. How can I safely run

紧接着上一篇，本文我们对go-admin下载后的源码进行分析。 首先对项目所使用的第三方库进行分析，了解作者使用的库是否是通用的官方库可以有助于我们更快地阅读程序。接着对项目的main()方法进行分析，因为程序使用cli的方式启动，对cli不同的命令进行分析。基于此俩点开始工作。 go-admin中使用的第三方库 cobra 强大的cli封装，支持命令嵌套 cast 简单安全的类型转换 casbin 轻量级开源访问控制框架，采用了元模型的设计思想，支持多种经典的访问控制方案，如基于角色的访问控制 RBAC、基于属性的访问控制 ABAC 等 gorm 一个神奇的，对开发人员友好的 Golang ORM 库 sentinel-golang 随着微服务的流行，服务和服务之间的稳定性变得越来越重要。Sentinel 是面向分布式服务架构的流量控制组件，主要以流量为切入点，从流量控制、熔断降级、系统自适应保护等多个维度来帮助您保障微服务的稳定性。 opentracing-go 分布式追踪库 cron 定时任务库，支持cron表达式 启动分析 main.go作为程序第一个入口文件，main()方法作为程序入口 使用corboa命令行的方式进行启动，有多个不同的命令，如下所示 查看系统版本 go-admin version 查看系统配置 go-admin config 服务启动 go-admin

cron-like recurring task scheduler design

由 泄露秘密 提交于 2021-02-17 22:12:24
问题 Say you want to schedule recurring tasks, such as: Send email every wednesday at 10am Create summary on the first day of every month And you want to do this for a reasonable number of users in a web app - ie. 100k users each user can decide what they want scheduled when. And you want to ensure that the scheduled items run, even if they were missed originally - eg. for some reason the email didn't get sent on wednesday at 10am, it should get sent out at the next checking interval, say

问题 I followed some other posts in stackoverflow and successfully setup cron with RVM using rvm cron setup and injected some ENV to the crontab file. When I was troubleshooting why the dotenv gem is not working, I realised the following: I placed my test.rb in file path /home/myuser/ruby/test.rb and had my crontab file as shown below: * * * * * ruby /home/myuser/ruby/test.rb >> /home/myuser/ruby/output.log and when I puts the output of the test.rb with Dir.pwd .
