Ejemplo
rows = [
{"dept": "eng", "salary": 100},
{"dept": "eng", "salary": 120},
{"dept": "sales", "salary": 80},
]
aggregate_by_group(rows, group_by=["dept"], aggs={"salary": "mean"})
# [{"dept": "eng", "salary": 110.0}, {"dept": "sales", "salary": 80.0}]
Notas
Funcion pura sin dependencias externas (solo collections.defaultdict de stdlib). Preserva el orden de primera aparicion de cada grupo. La funcion 'collect' no filtra None — acumula todos los valores incluyendo None.
