Citus Blog

Citus is a great extension for scaling out Postgres databases horizontally. You can use Citus either on the cloud on Azure or you can download Citus open source and install it wherever. In this blog post, we will focus on Citus open source packaging and installation.

When you go to the Citus download page to download the Citus packages—or you visit the Citus open source docs—many of you jump straight to the install instructions and the particular OS you’re looking for. That way, you can get straight to sharding Postgres with Citus.

But what if you want to see which operating systems the Citus packages support? Or what if you want to install Citus with an older version of Postgres?

This post will answer these types of nitty-gritty questions about Citus packages and their usages. Specifically, this post will cover these questions:

The last two months, I managed the agenda for our weekly Citus team meeting, the one time each week where our entire distributed team—with people spread across 6 different countries—gets together to talk about Citus things.

Not a surprise, as Joe’s content tends to be pretty popular, both on his personal blog, and on the Citus Data blog, including high traffic posts such as 5 ways to paginate in Postgres and Faster PostgreSQL Counting.

And when Joe agreed to let me interview him about his work on the Citus documentation (he’s quite busy so I wasn’t sure he would say yes), well, I was thrilled. This post is an edited transcript of my interview with Joe—and it’s your inside baseball view into how the documentation for the Citus open source project gets made.

About once a month I get this question: "How do I contribute to Postgres?". PostgreSQL is a great database with a solid code base and for many of us, contributing back to open source is a worthwhile cause. The thing about contributing back to Postgres is you generally don't just jump right in and commit code on day one. So figuring out where to start can be a bit overwhelming. If you're considering getting more involved with Postgres, here's a few tips that you may find helpful.
