Apache Kafka on Heroku is Now Generally Available

Many of the compelling and engaging application experiences we enjoy every day are powered by event-based systems; requesting a ride and watching its progress, communicating with a friend or large group in real time, or connecting our increasingly intelligent devices to our phones and each other. Behind the scenes, similar architectures let developers connect separate services into single systems, or process huge data streams to generate real-time insights. Together, these event-driven architectures and systems are quickly becoming a powerful complement to the relational database and app server models that have been at the core of Internet applications for…

SSL Is Now Included on All Paid Dynos

Encrypted communication is now the norm for applications on the Internet. At Heroku, part of our mission is to spread encryption by making it easy for developers to setup and use SSL on every application. Today we take a big step forward in that mission by making Heroku SSL generally available, allowing you to easily add SSL encryption to your applications with nothing more than a valid SSL certificate and custom domain.

Heroku SSL is free for custom domains on Hobby dynos and above and relies on the SNI (“Server Name Indication”) extension which is now supported by…

Handling Very Large Tables in Postgres Using Partitioning

One of the interesting patterns that we’ve seen, as a result of managing one of the largest fleets of Postgres databases , is one or two tables growing at a rate that’s much larger and faster than the rest of the tables in the database. In terms of absolute numbers, a table that grows sufficiently large is on the order of hundreds of gigabytes to terabytes in size. Typically, the data in this table tracks events in an application or is analogous to an application log. Having a table of this size isn’t a problem in and of itself,…

Dawn of the Dead Ends: Fixing a Memory Leak in Apache Kafka

At Heroku, we're always working towards increased operational stability with the services we offer. As we recently launched the beta of Apache Kafka on Heroku , we've been running a number of clusters on behalf of our beta customers.

Over the course of the beta, we have thoroughly exercised Kafka through a wide range of cases, which is an important part of bringing a fast-moving open-source project to market as a managed service. This breadth of exposure led us to the discovery of a memory leak in Kafka, having a bit of an adventure debugging it, and then…
