samuelcolvin opened a new pull request, #11314: URL: https://github.com/apache/datafusion/pull/11314
Demonstrates #11162 - union columns (and scalars) never match an `is null` check. This applies to both sparse and dense unions. Similarly union columns alwasy match a `is not null` check. This is particularly problematic for `datafusion-functions-json`, where users will often want to use `field->'foo' is not null`, see https://github.com/datafusion-contrib/datafusion-functions-json/pull/24. This is soon going to become problematic for us, hence working on it. I'll add more details on #11162. -- This is an automated message from the Apache Git Service.
