Uwe L. Korn updated ARROW-1715:
-------------------------------
Description: At the moment the types
{{pyarrow.Column/ChunkedArray/RecordBatch/Table}} cannot be pickled. Although
it may not be the fastest way to transport them from one process to another, it
is a very comfortable one. We should implement a {{__reduce__()}} for all of
them. (was: At the moment the types
{{pyarrow.Column/ChunkedArray/RecordBatch/Table}} cannot be pickled. Although
it may not be the fastest way to transport them from one process to another, it
is a very comfortable one. We should implement a {{__reduce__()}} for all of
them. For Array, this means that we need to pickle the buffers and save the
array type with them. The other classes require the pickling of the Array class
and will need to store the addditional metadata like the schema also in the
pickle data.)
