[Blog Update] SQLServerFAQ posts for September

September has been a content month for me both on the SQLServerFAQ blog on MSDN as well on this blog. Here is a round up of my posts on SQLServerFAQ for September:

I was intrigued by this when someone asked me what the Scan Count value meant w.r.t. SEEKs/SCANs:

Troubleshooting Error 511 using XEvents

Ran into a Compile Lock blocking issue because the Stored Procedure being used had an Open Symmetric Key command in it. Here is the post talking about the issue and how to workaround it:

This has been an age long debate on whether to use GUIDs or INTs. Thought I would pen down some points based on some tests that I ran on my test machine.

GUID vs INT Debate

SQL Backup softwares can cause Out Of Memory conditions if the BufferCount and MaxTransferSize is not taken into account on 32-bit systems:

Incorrect BufferCount data transfer option can lead to OOM condition

In the recent past, I worked on a few issues where the use of monotonically increasing clustered index keys were turning into hotspots in the database leading to latch blocking and causing performance degradation as an end result. I illustrate this with the help of an example in the blog post below.
