Can you elaborate on how that could work? Does arrow really allow for abstracting away the need for serialization even in JS - server scenarios? I though it was more of a shared memory data frame utility ?

There is an early arrow example in the examples package - superstore-arrow.html. The idea is that, instead of converting your data to internet->text->JSON->ArrayBuffer, you just keep the data in binary and write it directly into the C++ heap ArrayBuffer as-is. We currently do not read this in C++ directly for various reasons related to how emscripten allocates memory, but the general idea is the same.
