Wes McKinney created ARROW-3789:
-----------------------------------
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
