When API requests are made one-after-the-other they'll quickly hit rate limits and when that happens:

If you provide an API client that doesn't include rate limiting, you don't really have an API client. You've got an exception generator with a remote timer.

That tweet spawned a discussion that generated a quest to add rate throttling logic to the platform-api gem that Heroku maintains for talking to its API in Ruby.

If the term "rate throttling" is new to you, read Rate limiting, rate throttling, and how they work together

The Heroku API uses Genetic Cell Rate Algorithm (GCRA) as described by...

It is never easy to know how to react, communicate, or at times, even feel, during something as heartbreaking and real as the struggles that our fellow humans face through no fault of their own. As Herokai, we stand in solidarity with the Black Lives Matter movement and want to share some of our thoughts on the struggle, as well as some actions and resources that we find helpful.

We will be keeping this post updated and would love to include your voice. Please send us any thoughts that you’d like to share at: feedback@heroku.com.

“Many, if not all, of us are watching the civil rights movement taking place around the world. We are hurting, we are angry, and many of us are asking, “How...

Over the last few years, GraphQL has emerged as a very popular API specification that focuses on making data fetching easier for clients, whether the clients are a front-end or a third-party.

In a traditional REST-based API approach, the client makes a request, and the server dictates the response:

$ curl https://api.heroku.space/users/1 { "id": 1, "name": "Luke", "email": "luke@heroku.space", "addresses": [ { "street": "1234 Rodeo Drive", "city": "Los Angeles", "country": "USA" } ] }

Some say that the only constant in life is change. That may be true, but often what’s more important than the change itself is how we react. We all go through life trying to manage change (albeit with varying degrees of success), so we can better cope with it, learn from it, and adapt. Like individuals, organizations can learn the same “life skill,” so that change is not only less disruptive, but it also becomes a measure of organizational health that can lead to success.

Sometimes, it takes a pandemic

Times of sudden change, like during the COVID-19 crisis, are especially tough on everyone. Most companies are scrambling to figure out their “new normal;” employees and teams are...

This blog post is based on From Project to Productionized, a talk given at PyCon 2020 at the height of the COVID-19 pandemic. You can use this post today to learn how to deploy a Python application on Heroku. More specifically, we’ll show you how to deploy Django apps, including setting up your Django configuration, building continuous delivery pipelines, adding middleware, and everything else that goes into deploying Django on Heroku.
