All Eyes on the Wrong Problem: How Mitigations Distract from Real Performance Pain

The biggest lesson I’ve learned from helping folks manage data in Azure is this: if you’ve got a truly terrible problem you’d rather people didn’t notice, a great way to hide it is by educating your support staff and users about something bad but not AS terrible— something with a small mitigation—and constantly refocusing them on that.

The user base— and even your own support staff— will think that anyone who talks about the bigger issue just doesn’t understand how to fix the “known” problem.

‘Is it just me, or is SQL Server quality slipping?’

I asked myself that question for couple/few years until I faced up to it: SQL Server is well into a period where Microsoft investment is waning, and Microsoft regularly isn’t able to deliver the features they promise.

What are your stories of unbelievably bad performance from cloud vendors? I’ll go first. For years, Azure SQL Managed Instance’s General Purpose Tier has documented ‘approximate’ storage latency as being “5-10 ms.” This week they added a footnote: “This is an average range. Although the vast majority of IO request durations will fall under the top of the range, outliers which exceed the range are possible.”

How to Survive Opening a Microsoft Support Ticket for SQL Server or Azure SQL

Asking Microsoft for support for SQL Server or Azure SQL is a lousy experience these days, whether you’re using a cheaper service tier or the more expensive support tier formerly known as “Premiere Support.” You need to know a lot about the root cause of your problem and how to solve it, or your request will be dismissed with misinformation. You’ll need data and metrics to back up your claims to get the ticket escalated, and you’ll need to provide those receipts multiple times. Once escalated to the Product Group, you may get a helpful response, but it takes a while. If the answer is relayed through a lower support tier, it often won’t make much sense.

These issues aren’t due to bad work ethics or personal failings of support workers. These are good humans trying their best. The problem is worse because it’s systemic.
