Cloning Master Admin User Permissions in Amazon RDS for SQL Server with Fine-Grained Control
This article explores how to securely clone the master user permissions in Amazon RDS for SQL Server using a custom stored procedure, usp_rds_clone_login. It outlines a step-by-step process to generate, review, and apply a script that replicates server- and database-level access from the master user to a new login without directly exposing elevated credentials. The guide emphasizes the principle of least privilege, supports named account management, and enables transparent, auditable permission handling for DBAs and applications. Designed for secure and scalable environments, this solution enhances operational security while maintaining administrative flexibility in Amazon RDS.

Zero-Trust Architecture for Cloud-Based AI Systems
Zero-Trust Architecture (ZTA) emerges as a strong security paradigm for cloud-based AI systems, fundamentally operating on the principle of “never trust, always verify.” Unlike conventional security models, ZTA assumes potential compromise exists within the network and requires continuous verification of every access request regardless of origin.

Unmasking CXPACKET and CXCONSUMER in SQL Server: What Your Execution Plan Isn’t Telling You
This article dives deep into cxpacket and cxconsumer in sql server, explaining how to simulate each, when they appear, and why they matter. Using live execution plans, wait monitoring, and worker thread diagnostics, we uncover how uneven parallelism triggers thread sync waits—and how SQL Server sometimes hides real issues behind innocent-looking CXCONSUMER waits. Includes step-by-step queries, tuning tips, and a real-world scenario where repartition streams quietly ruined performance.

State Transition Constraints
About two decades ago, I introduced the concept of transition constraints to show Data Validation in a database is a lot more complex than seeing if a string parameter really is an integer. In October of 2008, I did an article called Constraint Yourself! on how to use DDL constraints to assure data integrity. One of the topics in that piece was a look at state transition constraints via an auxiliary table.

DISTINCT and UNION: What happens when you use them together?
When I was perusing my LinkedIn feed the other day, I came across this thread about using SELECT *. In one of the replies, Aaron Cutshall noted that: “Another real performance killer is SELECT DISTINCT especially when combined with UNION. I have a whole list of commonly used hidden performance killers!”

How SQL Server 2025’s Optional Parameter Plan Optimization Works
SQL Server 2025 improved PSPO to handle multiple predicates that might have parameter sensitivity, and that’s great! I love it when Microsoft ships a v1 feature, and then gradually iterates over to make it better. Adaptive Memory Grants were a similar investment that got improved over time, and today they’re fantastic.
