> but it seems like you could store data columnulary by type to get efficient vectorization and access patterns for operations over types I tried at first to be fully columnar, then cave and try hybrid then now I doing mostly rows with 2d NDArrays. The major reason is that going columnar flip everything and then I need to recreate tons of API, in special costly with FFI or APIs. I was looking into mimicking kdb+, and yes, that is what they end up doing. This lead to a more insular community (that I don't have but well, that is a worry!)
