Today we are announcing a beta release of our new streaming data connector between Heroku Postgres and Apache Kafka on Heroku. Heroku runs millions of Postgres services and tens of thousands of Apache Kafka services, and we increasingly see developers choosing to start with Apache Kafka as the foundation of their data architecture. But for those who are Postgres-first, it is challenging to adopt without a full app rewrite. Developers want a seamless integration between the two services, and we are delivering it today, at no additional charge, for Heroku Private Spaces and Shield Spaces customers.

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

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.

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" } ] } 

But, in GraphQL, the client determines precisely the data it wants from the server....


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.
