Citus Blog

On one of the Postgres community chat forums, a friend asked me: "Is there a blog post that outlines all the work that is being done on Postgres at Microsoft? It's hard to keep track these days."

And my friend is right: it is hard to keep track. Probably because there are multiple Postgres workstreams at Microsoft, spread across a few different teams.

In this post, you'll get a bird's eye view of all the Postgres work the Microsoft team has done over the last year. Our work includes some pretty significant improvements to the Postgres managed services on Azure, as well as contributions across the entire open source ecosystem—including commits to the Postgres core; new releases to Postgres open source extensions like Citus and pg_cron; plus ecosystem work on Patroni, PgBouncer, pgcopydb. And more.

The latest episode of Path To Citus Con—the monthly podcast for developers who love Postgres—is now out. This 6th episode featured guests Chelsea Dole and Floor Drees on the topic “You’re probably already using Postgres: What you need to know”.

The conversation explored the app developer perspective on Postgres. Many of you app developers are already using Postgres, but perhaps on top of an ORM. If you want to optimize your application, if you want to better understand the underlying database: what do you need to know? And how do you remove the fear? This episode of Path To Citus Con, our new podcast for developers who love Postgres, focuses on opportunities for building your knowledge in the database internals space—whether you want to go breadth-first or depth-first.

In this post, you’ll get a bit of backstory on the topic and the guests of Episode 06 of Path To Citus Con; and you’ll get a peek at highlights of a few interesting moments from the show. At the end of the post, you’ll find all the links of where you can listen to this and every episode of the podcast. Some people love these “human side of Postgres” podcast episodes—hopefully you will, too.

The topic of this month's PGSQL Phriday #011 community blogging event is partitioning vs. sharding in PostgreSQL. It seemed right to share a perspective on the question of "partitioning vs. sharding" from someone in the Citus open source team, since we eat, sleep, and breathe sharding for Postgres.

Postgres built-in "native" partitioning—and sharding via PG extensions like Citus—are both tools to grow your Postgres database, scale your application, and improve your application's performance.

What is partitioning and what is sharding? In Postgres, database partitioning and sharding are techniques for splitting collections of data into smaller sets, so the database only needs to process smaller chunks of data at a time. And as you might imagine, work gets done faster when you're processing less data.

In this post, you'll learn what partitioning and sharding are, why they matter, and when to use them. The table of contents:
