---------------------------------
Summary: [Plasma] Unify plasma client get function using metadata.
Key: ARROW-3555
URL: https://issues.apache.org/jira/browse/ARROW-3555
Project: Apache Arrow
Issue Type: New Feature
Reporter: Yuhong Guo
Sometimes, it is very hard for the data consumer to know whether an object is a
buffer or other objects. If we use try-catch to catch the pyarrow
deserialization exception and then using `plasma_client.get_buffer`, the code
is not clean.
We may leverage the metadata which is not used at all to mark the buffer data.
In the client of other language, this would be simple to implement.
