Hi Everyone,
I've got two questions that I'd like help with:
1. Pandas and numpy arrays can handle multiple types in a sequence eg. a
float and a string by using the dtype=object. From what I gather, Arrow
arrays enforce a uniform type depending on the type of the first
encountered element in a
Note that for the Python bindings, the reference counting is done
automatically, see
https://github.com/apache/arrow/blob/master/python/pyarrow/plasma.pyx#L182
which is e.g. used as the base object for numpy arrays whose memory is
backed by the object store.

Evicted objects are gone for good, although it would certainly be possible
to add the ability to persist them to disk.
The Plasma store does reference counting to figure out which clients are
using which objects. Clients can "release" objects through the client API
to decrement the reference
Great, thank you very much.
What happens to the evicted objects? are they
gone for good or are they persisted locally?
Also, what defines "objects that are not currently in use by any client"?
reference counting?
