Download the Current Stack Overflow Database for Free (2021-06)

Last Updated June 17, 2021

Stack Overflow, the place where most of your production code comes from, publicly exports their data every couple/few months. @TarynPivots (their DBA) tweets about it, and then I pull some levers and import the XML data dump into SQL Server format. Stack Overflow’s database makes for great blog post examples because it’s real-world data: real data…

Creating Basic Indexes on the Stack Overflow Public Database

Last Updated September 3, 2017

Indexing, Stack Overflow

My public SQL Server database copy of the Stack Overflow data dump only includes clustered indexes by default. I want to keep your database size as small as possible for quick downloading.

Carry on It turns out that the only thing harder than checking for new databases restored to a SQL Server, is checking a folder for a backup of a database that doesn’t exist on another SQL Server. These are both part of what sp_AllNightLog has to do. The other components, which use workers and a…

Building stuff I sometimes really hate coming up with ideas, and much prefer someone to just say “I want this” so I can go out into the world and figure out how to do that. Occasionally though, I realize that I’m not going to get all that much direction. That’s what happened with sp_BlitzQueryStore. It…

Backup and Recovery, First Responder Kit, kCura Relativity

In our Faux PaaS project, we need a backup plan – or rather, a restore plan. On each SQL Server instance, clients can create as many databases as they want, anytime they want, with no human intervention. We need those databases covered by disaster recovery as quickly as practical. SQL Server’s newer disaster recovery options – Always On Availability Groups and…

Background: I’m working with kCura to build a Faux PaaS: something akin to Microsoft’s Azure SQL DB, but internally managed.

In the cloud, treat your servers like cattle, not like pets. Rounding up a herd of servers in Texas In the cloud, systems administration is very different than the on-premises stuff you’re used to. When you build VMs in the cloud with Infrastructure-as-a-Service (IaaS, meaning AWS EC2, GCE, or Azure VMs), you expect them to…

Always On Availability Groups, Stack Overflow

Today’s brief Stack Overflow outage reminded me of something I’ve always wanted to blog about: Stack Overflow is in limp-home mode There’s a gray bar across the top that says, “This site is currently in read-only mode; we’ll return with full functionality soon.” That’s not a hidden feature of Always On Availability Groups. Rather, it’s a…

I use a Microsoft SQL Server version of the public Stack Overflow data export for my blog posts and training classes because it’s way more interesting than a lot of sample data sets out there.
