    Good question, I think there's many different lessons. To your point about bitmasks, you can imagine that each component (i.e. column) has an array of data and a large bitmap that identifies whether a component is present or not. Had to build a SIMD implementation so you can do and, and not, or and xor operations on millions of components within reasonable amount of time. Interestingly enough, you still need a hashmap or b+tree in case you want to retrieve a component by it's ID instead of an index, but the rest of things can be modeled with bitmap indexes.

    I'm reevaluating some of my practices in Go and one of them is the idea of verifying everything before usage to prevent runtime panics. For example, how do you ensure something is properly initialized before it's used? I was thinking on introducing a state machine to controllm this kind of thigs. What do you think? https://github.com/looplab/fsm
