I had the same understanding as Corey and thought that apps shared an allocated
memory space for the sole purpose of eliminating the need to copy data between
the apps. If it's just a replacement for protobuf SERDE, that makes it a whole
lot less exciting :(

Subject: Re: Question about mutability
I don't think one application/process's memory space will be made available to
other applications/processes. It's fundamentally hard for processes to share
their address spaces.
IIUC, with Arrow, when application A shares data with application B, the data
is still duplicated in the memory spaces of A and B. It's just that data
serialization/deserialization are much faster with Arrow (compared with
Protobuf).
