Rob Conery’s post: Virtual, Computed Columns in PostgreSQL 12

Rob Conery is extremely excited about one of the new features in PostgreSQL 12: Generated (or computed) columns. Generated columns are special columns that are always computed from other columns.

Come say hello at PgDay San Francisco

On January 21, 2020, the magic of the 1-day, single-track Postgres community event comes to San Francisco. Our Postgres team Microsoft is a big fan of these 1-day “PgDay” events that pack so much useful information & so many Postgres people in one place for a whole day. So we’ve joined a growing list of companies to support the community event, and we will be a premiere sponsor; we also signed up to sponsor the live captioning (because, accessibility). The CFP just closed with 10 proposals for every slot, so you know the sessions are going to be great.

Architecting petabyte-scale analytics by scaling out Postgres on Azure with the Citus extension

Claire Giordano sat down with engineer Min Wei of Microsoft to find out how the Windows team assesses the quality of new software builds, to decide if the next software update is ready to ship. The part of the answer we love best is that Min’s team scales out Postgres on Azure—using Citus—to power a 1.5 petabyte (and growing) analytics dashboard, analyzing 20K types of metrics from over 800M Windows devices. Read on to find out what Claire learned.

Database constraints in Postgres: The last line of defense

Constraints are an extremely powerful construct for your database. And when it comes to your database, constraints are the last line of defense. Inspired by his popular talk, Will Leinweber explains how constraints are essentially rules that your data has to follow.
