I've watched some of these and the material and teacher are awesome. Two questions come to mind:<p>1. A ton of effort seems to be spent on making things run in parallel, but that introduces quite a bit of overhead too, so how well does a sequential baseline actually perform? By sequential baseline I mean a single thread that just executes all incoming transactions one by one in sequence.<p>2. This course seems to spend a lot of time on things that the teacher says are things you shouldn't do anyway. For instance there is an entire lecture on skip lists and Bw-trees, and at the end the teacher mentions that these are terrible. This is interesting from a historical perspective, but not only does this take a lot of time, I also lose track of which things you should and which things you shouldn't do. It'd be interesting to have a compressed course that spends less time on things you should not do, perhaps by adding annotations to the video to skip sections that are about things you should not do.
