What other educational databases are you looking at? Curious in case I'm missing any of them.

RisingLight, SimpleDB by Edward Sciore, SimpleDB for the MIT course are the main ones that come to my mind immediately. I forgot that Erik Grinaker's ToyDB implements MVCC but I remember it being hard to grok and not very straightforward.

There is also BusTub from CMU which I stumbled upon earlier today:
