Delaying Asynchronous Message Processing
June 14, 2017
At Indeed, we always consider what’s best for the job seeker. When a job seeker applies for a job, we want them to have every opportunity to be hired. It is unacceptable for a job seeker to miss an employment opportunity because their application was waiting to be processed while the employer makes a hire. The team responsible for handling applies to jobs posted on Indeed maintains service level objectives (SLOs) for application processing time. We constantly consider better solutions for processing applications and scaling this system.
Component Scanning Library Code
April 18, 2017
Component scanning packages can be both your best friend and worst nightmare. In this post, I will cover several bad practices when it comes to component scanning. In detailing a few of these anti-patterns, I will also offer a few better patterns that are much cleaner to use.
Spring Bean Method Invocation
April 01, 2017
In my day to day development, I spend a fair bit of time working with Spring since it offers a lot of scaffolding to get a project off the ground. At Indeed, I spent a fair bit of time upgrading us from Spring 3 to Spring 4 and came across many good uses of Spring and many bad ones too. In this Bad Practices series, I will talk about some of these bad practices, why they should be avoided, and what you can do instead.
Gracefully Degrading Functionality Using Status
January 19, 2017
In a previous blog post, we described how to use our Status library to create a robust health check for your applications. In this follow-up, we show how you can check and degrade your application during an outage by:
- short-circuiting code paths of your application
- removing a single application instance from a data center load balancer
- removing an entire data center from rotation at the DNS level
Docker Machine DNS Resolution using Consul
May 08, 2016
Developers at Indeed have recently switched over to using docker for local development. Being one of the earlier adopters, I fell in love with the type of workflow that it enabled. It allowed me to create seamless environments between both my desktop and portable workstation. The tooling did this by allowing you to resolve container names as hosts in your web browser. For example, if I had a web application named indigo running on port 4000, I could go to http://indigo:4000 to access that application. After a few weeks of enjoying the simplicity of this development workflow, I craved a similar type of environment for some of the larger scale projects that I do at home. In this blog post, I will cover some of the basics that allowed me to enable this type of development.
