Wes McKinney commented on ARROW-3829: ------------------------------------- I'm moving this to 0.13. If you submit an alpha / experimental version of this for 0.12, please go ahead =) > [Python] Support protocols to extract Arrow objects from third-party classes > ---------------------------------------------------------------------------- > > Key: ARROW-3829 > URL: https://issues.apache.org/jira/browse/ARROW-3829 > Project: Apache Arrow > Issue Type: Improvement > Components: Python > Reporter: Uwe L. Korn > Assignee: Uwe L. Korn > Priority: Major > Fix For: 0.13.0 > > > In the style of NumPy's {{__array__}}, we should be able to ask inputs to > {{pa.array}}, {{pa.Table.from_X}}, ... whether they can convert themselves to > Arrow objects. This would allow for example to turn objects that hold an > Arrow object internally to expose them directly instead of going a conversion > path. > My current use case involves Pandas {{ExtensionArray}} instances that > internally have Arrow objects and should be reused when we pass the whole > {{DataFrame}} to {{pa.Table.from_pandas}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
