### Is your feature request related to a problem or challenge? Follow on to https://github.com/apache/arrow-datafusion/issues/6119 For efficient use of arrays `arrow-datafusion` should support some operations: - [ ] Concatenate (use operator `||`) (`array_concat`, `array_append` and `array_prepend` analog) - [ ] Intersection (use operator `&&`) (not PostgreSQL analog!) ### Describe the solution you'd like Examples: ``` select make_array(1, 2, 3) || make_array(4, 5, 6); ---- [1, 2, 3, 4, 5, 6] ``` ``` select 1 || make_array(2, 3, 4); ---- [1, 2, 3, 4] ``` ``` select make_array(1, 2, 3) || 4; ---- [1, 2, 3, 4] ``` ``` select make_array(1, 4, 3) && make_array(2, 1); ---- [1] ``` ``` select make_array(1, 2, 3, 4, 5) && make_array(1, 3, 6); ---- [1, 3] ``` ### Describe alternatives you've considered _No response_ ### Additional context https://www.postgresql.org/docs/current/functions-array.html -- This is an automated message from the Apache Git Service.
