  Not downvoting, but those two links don't really describe much - though they are part of the story. For other readers, here's a general takeaway - - Arrow Plasma was deprecated, and is now no longer even present in the Arrow project. - The maintainers behind the Plasma store in Arrow forked it, into Ray. Plasma is still alive and well in Ray - and it still uses the Arrow IPC format, among other things. In addition to the links from the above poster, read the original blog post on Plasma [0], and the section on Ray on [1]. I use Ray quite a bit.
