### Is your feature request related to a problem or challenge? 1. Since there are aggregate functions like `corr` and `covar`, it makes sense to me that we should add aggregate `distance`. 2. Beyond the aggregate function, it might also be valuable to add scalar UDFs like `list_distance`/`array_distance`, similar to DuckDB, along with other methods of distance measurement (e.g., like `cosine` etc). This function is particularly useful for scenarios involving spatial analysis, clustering, or similarity computations, where distance metrics are crucial. ### Describe the solution you'd like XREF: DuckDB [list functions](https://duckdb.org/docs/sql/functions/list.html#list_distancelist1-list2), [array functions](https://duckdb.org/docs/sql/functions/array#array_distancearray1-array2) > side note: `list` and `array` are different by their own definition. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
