ASF GitHub Bot commented on ARROW-640: -------------------------------------- wesm commented on issue #1765: ARROW-640: [Python] Implement __hash__ and equality for Array scalar values Arrow scalar values URL: https://github.com/apache/arrow/pull/1765#issuecomment-374795629 I just want to point out that the way we are interacting with scalar values in Python is not intended necessarily as the long term solution for the project. There's been some discussion in JIRA about adding some kind of C++-level scalar object model. So I'd just like to throw that out there as food for thought ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
