Korn commented on ARROW-86: ---------------------------------- PR: https://github.com/apache/arrow/pull/52 > Python: Implement zero-copy Arrow-to-Pandas conversion > ------------------------------------------------------ > > Key: ARROW-86 > URL: https://issues.apache.org/jira/browse/ARROW-86 > Project: Apache Arrow > Issue Type: Improvement > Components: Python > Reporter: Uwe L. Korn > Assignee: Uwe L. Korn > > For this to work, we need: > * a check if the Arrow Array could be represented as Pandas Series using the > same memory buffer > * a {{numpy.ndarray}} subclass that keeps a reference to the Arrow Array > With the NumPy C-API it is already possible to create a {{numpy.ndarray}} > instance that uses the Arrow Array memory buffer internally but there is no > way to keep track if the {{numpy.ndarray}} still lives or the underlying > memory can be free'd. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
