Citus 7.4: Move fast and reduce technical debt

We are happy to announce the latest version of the Citus distributed database, Citus 7.4. Over the last 2 years, our focus on shorter release cycles & a myriad of new features caused us to accumulate some technical debt. So, in Citus 7.4, we focused on reducing technical debt in our planner logic, and in code paths that became obsolete over the years. All this helps us maintain our release velocity so we can add even more new features faster. See what we did.

This post on recursive CTEs hit the front page of Hacker News last week. For applications that deal with ecommerce and shopping categories, recursive CTEs are a great help. Craig explains why next time you need to do some recursive computation across your data, you should consider doing it directly in SQL rather than loading all that data into your app.

So happy Freshworks chose Citus to power their real-time chat analytics

Freshchat by Freshworks is a messaging service that provides near real-time and historical analytics. The Freshchat goal: to enable customers to measure response times and better understand the end user experience. Companies using Freshchat can easily determine whether they’re meeting service-level agreements (SLAs), decide whether they need to increase or reduce staff, and quantify Freshchat’s impact on the organization. So happy that Citus plays a role in Freshchat’s mission.

It’s the future (for databases)

For many developers, the default is to “just use Postgres.” Here’s what a few questions on schema designs can lead to. Yes, it’s satire. From Craig, of course.
