SQL Saturday #800 – the annual BI Edition for Atlanta, GA, took place on Saturday, September 22nd at the new Microsoft Avalon offices in Alpharetta, GA. This was the second large-scale event I’d attended in this space (the first being Azure Data Fest). Initially, I’d had some reservations about the size of rooms vs. the number of attendees, but everything was planned excellently and no session on my wishlist was over capacity to the point where seats weren’t available. No small feat for the planners! The entire day went off great and the sessions were some of the best I’d attended to date. Unofficially, it seemed the like underlying theme of the event was performance tuning SSAS Tabular and Power BI, which was very timely for me as that is currently an area I’m focusing on.
