---------------------------------------------

             Summary: [C++] DictionaryBuilder should support bootstrapping from 
an existing dict type
                 Key: ARROW-4776
                 URL: https://issues.apache.org/jira/browse/ARROW-4776
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Francois Saint-Jacques


This would mean adding a new DictionaryBuilder constructor that receives a 
dictionary type and performs a lazy deep copy if there's any modification. 
We'll have to investigate how this translate in API ergonomics.
