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

             Summary: [Python] Enable calling object in Table.to_pandas to 
"self-destruct" for improved memory use
                 Key: ARROW-3789
                 URL: https://issues.apache.org/jira/browse/ARROW-3789
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Wes McKinney
             Fix For: 0.13.0


One issue with using {{Table.to_pandas}} is that it results in a memory 
doubling (at least, more if there are a lot of Python objects created). It 
would be useful if there was an option to destroy the {{arrow::Column}} 
references once they've been transferred into the target data frame. This would 
render the {{pyarrow.Table}} object useless afterward
