Stop using sp_hexadecimal & sp_help_revlogin

Since I started at Stack Overflow (read archived tweet) , I’ve had the chance to see some of the interesting challenges with running our databases at our scale.

My coworker Taryn Pratt (blog) recently blogged about fighting with deadlocks related to Stack Overflow for Teams.

Lots of logins

Taryn mentions in her post that each team gets their own login, user, schema, etc. This means we have a lot of logins. Additionally, we use Availability Groups for our High Availability, which means we need to keep those logins in sync across AG Replicas.

Code to purge data based on creation date

Thu, 04 Apr 2019 08:30:16 -0400

Yesterday, I talked about batching deletes, and the day before I talked about how much I like to delete data, and why it’s necessary to do it, despite being a data packrat.

Today, let’s look at just one scenario, and how I like to handle it. In my experience, this is one of the most common purge requirements (and probably the easiest), so first, let’s look at the business requirements.

Purging data with batched deletes

Yesterday, I wrote about the importance of planning your data purges. Today, let’s look at the simplest requirement for purging data: Keep data for X days after it’s created. There are tons of cases where this is the rule. Log data, telemetry data, even transactional data is often retained based on X days since it is created.

The thrill of purging old data

DBAs & Data professionals tend to be digital pack rats. My personal Google Drive is filled with random files that I refused to part with–even though it’s of questionable value. I lament that I do not have a copy of every paper I typed in high school or college–and I envy those who do. You never know when you’ll need notes from that meeting 6 years ago, or when you’ll need that funny GIF you created for an inside joke you no longer remember.

Building a Twitter-bot RSS Aggregator

I hate RSS readers

For some reason, about once a year, I go hunting for a new RSS reader so I can keep track of blogs that I like to read. It’s always the same process:

Dig through reviews to find an app that I think I will love.
Come up with a list of blogs that I like to read.
Install and configure RSS reader app.
Spend the night reading blog posts.
Use app for a week.
Never open RSS reader app again.

Well, it’s time to stop the insanity. Its time to stop doing the same thing over and over again, hoping it will work this time. Its time to find a solution that really works.
