Wes McKinney reassigned ARROW-3789: ----------------------------------- Assignee: Wes McKinney > [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 > Assignee: Wes McKinney > Priority: Major > Fix For: 1.0.0 > > > 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 -- This message was sent by Atlassian Jira (v8.3.4#803005)
