> The Arrow C data interface and C stream interface docs say that these interfaces are only for sharing data within a single process. This is not exactly correct. The fundamental requirement for using the C data interface and C stream interface is not that the components be necessarily running in the same process. It’s that they are able to pass around a pointer and access the same memory address space. Let's make some minor changes to the docs to clarify this.
