It has been over 4 weeks now that the very serious security bugs named Meltdown and Spectre, affecting almost any CPU made in the last decade, have been publicized and patches have been made available for various systems and software. Some patches even had to be withdrawn and recreated (AMD had not maintained its documentation). In […]

Introduction With the upcoming implementation of the European General Data Protection Regulation (GDPR) in May 2018, having a security concept in place is essentially required by law. Microsoft SQL Server, just like other database systems, carries the main asset to protect: the data itself. Therefore, it is time for an article from a more strategic […]
Lately, with the advance of SSDs, more and more administrators are wondering: Is the old rule to use a 64K Cluster size for SQL Server still applicable on today’s hard drives, especially SSDs or even Flash? And: Does it apply to all RAID-types equally? This summer I took some time to conduct some IO benchmarks […]
During the course of optimizing data-access-code with the In-Memory-functionalities in Microsoft SQL Server (memory optimized tables + indexes, memory optimized table valued parameters and natively compiled stored procedures), you may often realize that sometimes you go one step forward and then another one backwards.
It is no secret that I have been very active in the Asian region the last years – mainly in Singapore, Malaysia and India. So, it may not be a surprise that this summer I will be giving a full day PreCon at the now called “Data Platform Summit” in India’s hub for information technology: […]
First off, the most important information in a nutshell: From 26-28 June, I am conducting a new SQL Server Master-Class: The Performance Troubleshooting Bootcamp with SQLSentry (shorthand: PSS*). For those in a hurry, the link for registration right below: http://sql-server-master-class.com/#PSS

In this article I will bring together several techniques for troubleshooting a performance- and security-related “phenomenon” I recently noticed when doing some tests with Natively Compiled Stored Procedures.
These are just sublime news, there is no other way to put it: With the Service Pack 1 for SQL Server 2016 released today, Microsoft puts an end to the programming-technical differences between the editions (LocalDB, Express, Standard, Web, Enterprise)! As of today, EVERYONE who is already working on SQL Server 2016 can create In-Memory […]
After my Asia-tour this summer I feel it is about time for this article. At the time of this article (09-2016) I have presented at more than 50 technical conferences around the world (Europe, Middle East, Asia, North America), from small with about 150 attendees to huge with around 5000 attendees. With that came a […]
