This is pretty cool. As I was reading the code I really wished for an explanation or simple ASCII diagram of the serialization formats for the various node/record types, as well as for the frames/wal format. Given that the poster is the author of the project, I hope you'll consider filling in these kinds of details, as they'd presumably be of interest to the people you're "Show"-ing this to.
Thank you. I know what you mean, I'm not happy with how the serialization is done right now, it's too complicated.
Maybe someone on HN knows a Python serialization library beyond pickle that would allow to describe how the data is laid out and take care of the rest. It looks like struct is not flexible enough for this usage.
