The other commenter answering you is, I think, trying to point out that the Arrow plasma store is deprecated (and no longer present in the arrow project).

I think it's worth being a little more clear here - Arrow IPC is _not_ deprecated, and has massive momentum - so much so that it's more or less already become the default IPC format for many libraries.

To me it remains unclear what the benefits of Iceoryx2 over the Arrow ecosystem is, and what the level of interoperability is, and what the tradeoffs of either are relative to eachother. Within a single machine, you can mmap the IPC file. You can use Arrow Flight for inter-node or inter-process communication. You can use Arrow with Ray, which is where Plasma went.

I love anything new in this space though, if/when I have time I'll check this out - would love it if somebody could actually eloborate on the differences though.
