ARR — Array

Rules that catch inefficient or incorrect use of PySpark array functions.

Rule	Title
ARR001	Avoid array_distinct(collect_list()) — use collect_set() instead
ARR002	Avoid array_except(col, None/lit(None)) — use array_compact() instead
ARR003	Avoid array_distinct(collect_set()) — collect_set already returns distinct values
ARR004	Avoid size(collect_set()) inside .agg() — use count_distinct() instead
ARR005	Avoid size(collect_list()) inside .agg() — use count() instead
ARR006	Avoid size(collect_list().over(w)) — use count().over(w) instead
