Hi all,
could someone (Wes?) elaborate on that a bit more? Because the ray
project still lists Arrow Plasma as part of there infrastructure , e.g.
here : _
_
Also, from my understanding plasma is C++ and the client exists for C++,
and plasma is (still) part of Arrow. But the only documentation on how
to use plasma with Arrow is for python [2]. There is some docs for
plasma C++ here [3], but they do not seem to cover the interaction
between Arrow and plasma. Can you point me somewhere where I can find
something in that regard?
Thirdly out of curiosity: are there any data about performance
(throughput, latency) of plasma (both inter and intra process)?
Thanks a lot and best regards
Simon

hi Jacopo — absent developer-maintainers, it is de facto deprecated
since the previous developer-maintainers (who work on the Ray project)
have forked away and abandoned it. If someone wants to resume
development and maintenance of the codebase (or fund work on it,
please contact me if you want to fund it!), that would be great.

Hi everybody,
My name is Jacopo, I am a software engineer at Orchest (orchest.io). We
are currently making use of the plasma store to do in-memory data
passing, and use pyarrow for some serialization.
Some months ago, in the dev mailing list, there have been talks of the
plasma store getting deprecated. I see that Arrow 4.0.0 has been
released and that the plasma-store is still there, I could not find
exhaustive information in the docs and the README about the current
state of the plasma-store and what to expect in the future.
Could someone provide some insight as to what the current plans are for
plasma in pyarrow?
Regards,
Jacopo
