Mainly if it does what it says on the box. I've got a chapter in there, but I haven't seen all the other chapters. I'm curious how the team did....

To use sys.dm_os_buffers as part of a monitoring process, you just have to look for the two events, RESOURCE_MEMPHYSICAL_LOW or RESOURCE_MEMVIRTUAL_LOW. These are available in...

If the optimizer still thinks, based on statistics, a different index is more selective than your filtered index, that would explain why it's being selected. I can't say beyond that...

So, how's the material? You're reviewing more of the rough & ready aspect of getting the alpha, which is cool, but I'm curious how we did on the meat.
