Hi @andygrove, I'd like to work on this issue. I understand the problem: `explode_outer` should treat empty arrays `[]` the same as `NULL` arrays - both should produce a row with `NULL` value, unlike the current `unnest` behavior which skips empty arrays. Before I start implementing, I have a question about the approach: 1. **Option A**: Add a new flag like `preserve_empty_as_null` to the existing `unnest` function 2. **Option B**: Create a separate `explode_outer` function for Spark compatibility Which approach would you prefer? I'll start exploring the codebase and familiarizing myself with the `unnest` implementation in the meantime. Thanks! -- This is an automated message from the Apache Git Service.
