             Summary: Dictionary memo missing elements in id_to_dictionary_ map 
after deserialization
                 Key: ARROW-7512
                 URL: https://issues.apache.org/jira/browse/ARROW-7512
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
    Affects Versions: 0.15.0
            Reporter: Wamsi Viswanath


`id_to_dictionary_` map is empty after de-serialization of schema using 
ReadSchema method.

An example for reproduction:

[https://gist.github.com/wamsiv/77dc1db44b5805828172e6c94d61d2d9]

I see that it is probably being missed here: 
https://github.com/apache/arrow/blob/master/cpp/src/arrow/ipc/metadata_internal.cc#L804

Please let me know if the behavior is expected and if so then how the client is 
expected to have dictionary array values?
