Data Tales #2: The Case of the Exploding Table 1

I was recently at a customer site where the developers were very concerned about the impact of adding columns to a table. They told me that when they added a new column that their deployment code was timing out and the database was massively increasing in size. It had increased from around a small size to well over 50GB during the single operation. The deployment operation involved adding the column and writing one row to a deployment history table. Because they were only writing a single new row, they were blaming SQL Server for bloating the database size when a column was added.

Data Tales #1: The Case of the Auto-Truncating Table

I have a number of clients that I spend a day or two with each month. I like this style of engagement as I get to know the staff and their systems over a period of time, can see the improvements that we make over time. The staff members also know that if they have issues that aren't desperate, they can save them up for the days that I am onsite.

Looking forward to Containers

Virtualization has long been a staple when it comes to computing. In essence, virtualization is really just the use of abstraction to make things either easier to manage or more fault-tolerant. Disks, for example, have long been virtualized in the sense that a single, physical, can easily be divided up into multiple logical (or virtual) volumes (or drives) just as easily as a number of discreet physical disks can also be virtualized into a single drive (via RAID) – which can further be partitioned into volumes, LUNs, and so....More

AlwaysOn Availability Groups and SQL Server Jobs, Part 29: Practical Implementation Tips

My initial goal in writing this series of posts was to outline some of the concerns surrounding Availability Groups (AGs) and SQL Server Agent Jobs – and call out how there is virtually no guidance from Microsoft on this front and then detail some of the pitfalls and options available for tackling this problem domain. I initially expected this series of posts to have between 25 and 30 posts – according to some of the early outlines I created ‘way back when’....More
