A discussion overheard between two attendees at SQLSaturday yesterday: What is this Tabular thing? Like a cube but better. How's it better? It's in memory. I wonder if it can improve the performance of my report… It should, it's also in the Cloud. Note to myself. Use "in memory" and "cloud" more often.
