I’ll Make Them an Offer They Can’t Refuse

Over the past few weeks I’ve been flexing my network to try and get on an Azure DW project…and so far I’ve come up empty handed. Now granted, I could definitely be wrong about this… but I *thought* my offer was overly generous and guaranteed to land me on an Azure […]

How to Detect Locking and Blocking In Your Analysis Services Environment

Engaging the Formula Engine Cache with SSAS Tabular
