alamb opened a new issue #127: URL: https://github.com/apache/arrow-datafusion/issues/127
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-10963 An implementation of {{PartialEq}} for {{ScalarUDF}} and {{AggregateUDF}} was added in ARROW-10808 ([pull request|https://github.com/apache/arrow/pull/8836]), which was a requirement for the {{PartialEq}} derivation for {{Expr}}. The implementation checks equality on only the UDFs' {{name}} and {{signature}} fields: the underlying assumption is two UDFs with the same name and signature must be the same UDF. This assumption may hold up in a SQL context where UDFs are registered by name (therefore guaranteeing they are distinct), however, it doesn't hold up in a general case where there are no uniqueness requirements on the name. Improve the equality implementation for {{ScalarUDF}} and {{AggregateUDF}}. For additional context, see the discussion in the pull request [here|https://github.com/apache/arrow/pull/8836#discussion_r536874229]. -- This is an automated message from the Apache Git Service.
