All Eyes on the Wrong Problem: How Mitigations Distract from Real Performance Pain
🔥 UPDATE: Microsoft has announced the general availability of the Next-gen General Purpose service tier for Azure SQL Managed Instance, which includes improvements to I/O latency, IOPS, and transaction log throughput.

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.
This is the story of Azure General Purpose storage for Azure SQL Managed Instance and Azure SQL Database.
