Joris Van den Bossche created ARROW-6488: --------------------------------------------
Summary: [Python] pyarrow.NULL equals to itself Key: ARROW-6488 URL: https://issues.apache.org/jira/browse/ARROW-6488 Project: Apache Arrow Issue Type: Bug Components: Python Reporter: Joris Van den Bossche Fix For: 0.15.0 Somewhat related to ARROW-6386 on the interpretation of nulls, we currently have the following behaviour: {code} In [28]: pa.NULL == pa.NULL Out[28]: True {code} Which I think is certainly unexpected for a null / missing value. I still need to check what the array-level compare kernel does (NULL or False? ideally NULL I think), but we should follow that. -- This message was sent by Atlassian Jira (v8.3.2#803003)
