### Is your feature request related to a problem or challenge? Spark supports `explode` and `explode_outer`, which are very similar to DataFusion's existing `unnest` function. `explode_outer` treats nulls and empty arrays identically and produces an output row containing `null`. This differs from `unnest`, which only does this for null inputs and does not generate output for empty arrays. ### Describe the solution you'd like I propose adding a new flag to `unnest` to treat empty arrays consistently with null arrays. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
