10 Most-Read Citus Data Blog Posts in 2017, ft. Postgres

Top 10 Most Popular Citus Data Blog Posts in 2017 cover image

What Postgres and distributed database topics got the most attention on our Citus Data blog in 2017? Out of the 47 new posts we published last year, it’s pretty clear that many of you were interested in sharding relational databases, whether it be Ozgun’s principles of sharding or Craig’s post on figuring out which sharding data model is right for you. Heck, the five sharding data models post was so popular that it even got re-published recently on HackerNoon.

And it’s no surprise that given how many Rails developers love Postgres, both Postgres tips for Rails and scaling out multi-tenant apps on Rails were popular. What surprised me was that scaling out your Django multi-tenant app did not make our top 10 list. My theory, and what I told Sai, the author of the Django library for Citus, is that I think his Django/Citus post would totally have made the cut had it been published earlier in the year, with more time for people to discover the post. And I wish Craig’s awesome post about our Citus Cloud 2 and Postgres announcement had made the top 10 list—but alas, as it was also a November post. Same with the December 27th publication of Craig’s awesome post on building real-time analytics dashboards with Postgres & Citus.

I guess the popularity of our Citus posts is influenced by a different algorithm than the Oscars… you know how movies released at the end of the calendar year have a top-of-mind advantage when it comes to winning Academy Awards? Not so on the Citus blog. :)

Our engineering team dedicates a lot of energy to the blog, to share learnings about Postgres and our brand of worry-free Postgres that scales out. So it gives us a real sense of “job well done” that so many of you read the blog. And your recommendations are the best proof that we have added value to your day, so we appreciate it when you share and tweet our posts. Thank you!

Without any more fanfare, here are the 10 most-read posts published on the Citus Data blog in 2017, ordered by date of publication. Take a look to see what others were interested in, to see what you missed, and to see why old-school PostgreSQL is so hip again.

Scale Out Multi-Tenant Apps based on Ruby on Rails

BY LUKAS FITTL | All about the activerecord-multi-tenant Ruby library for Citus, which enables easy scale-out of apps that are built on top of Ruby on Rails and follow a multi-tenant data model.

How to Scale PostgreSQL on AWS–Learnings from Citus Cloud

BY OZGUN ERDOGAN | All the things we learned from Postgres users about what they really need, operationally. And why we built Citus Cloud as a fully-managed database as a service on AWS, one that natively integrates with Postgres in the cloud.

Scaling out complex SQL transactions in multi-tenant apps on Postgres

BY MARCO SLOT | Distributed databases often require you to give up SQL and ACID transactions as a trade-off for scale. Citus is a different kind of distributed database. All about how Citus enables you to scale out complex SQL queries in multi-tenant apps.
