> since Mode expression works with any child expression, and you special-cased handling Strings, how do we handle Array(String) and Struct(String), etc.? In my local tests, I found that Mode performs a byte-by-byte comparison for structs, which does not consider collation. So that is still outstanding. Good catch! @uros-db There are several strategies we might adopt to handle structs with collation fields. I am looking into implementations. It is potentially straightforward though have some gotchas. Do you feel I should solve for that in a separate PR or in this one? I assume you prefer that this get solve in this PR and not a follow-up PR, right? -- This is an automated message from the Apache Git Service.
