Announcing the New Heroku CLI: Performance and Readability Enhancements

Today we are announcing the newest version of the Heroku CLI. We know how much time you spend in the CLI as developers and how much pride you take in being able to get things done quickly. Our new CLI has big improvements in performance as well as enhanced readability for humans and machines.

Tuned for Performance

CLI response time is made up of two parts: the API response time and the performance of the CLI itself, and the latter is where we’ve made big improvements. While a typical Unix user should experience responses that are around half a …

Making the Most of PostgreSQL Databases on Heroku

Postgres is our favorite database—it’s reliable, powerful and secure. Here are a few essential tips learned from building, and helping our customers build, apps around Postgres. These tips will help ensure you get the most out of Postgres, whether you’re running it on your own box or using the Heroku Postgres add-on.

Use a Connection Pooler

Postgres connections are not free, as each established connection has a cost. By using a connection pooler, you’ll reduce the number of connections you use and reduce your overhead.

Most Postgres client libraries include a built-in connection pooler; make sure you’re using it.

PostgreSQL 9.6 Now Generally Available on Heroku

PostgreSQL 9.6 is now generally available for Heroku Postgres. The main focus of this release is centered around performance. PostgreSQL 9.6 includes enhanced parallelism for key capabilities that sets the stage for significant performance improvements for a variety of analytic and transactional workloads.

With 9.6, certain actions, like individual queries, can be split up into multiple parts and performed in parallel. This means that everything from running queries, creating indexes, and sorting have major improvements that should allow a number of different workloads to execute faster than they had in prior releases of PostgreSQL. With 9.6, the PostgreSQL community, …

Data Pipelines with Kafka and Functional Reactive Programming with Node.js

Heroku recently released [a managed Apache Kafka][1] offering. As a Node.js developer, I wanted to demystify Kafka by sharing a simple yet practical use case with the many Node.js developers who are curious how this technology might be useful. At Heroku we use Kafka internally for a number of uses including data pipelines. I thought that would be a good place to start.

When it comes to actual examples, Java and Scala get all the love in the Kafka world. Of course, these are powerful languages, but I wanted to explore Kafka from the perspective of Node.js. While there …

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 over twenty …
