Mulesoft DataWeave：转换平面列表

我对DataWeave比较陌生，我想知道如何/是否可以使用DataWeave而不是Java转换器来转换下面这样的消息

如果我有以下JSON用户负载，包括组和子组：

[{
    "GROUP": "GROUP_A",
    "SUBGROUP": "SUBGROUP A1",
    "USER": "USER 1"
}, {
    "GROUP": "GROUP_B",
    "SUBGROUP": "SUBGROUP B1",
    "USER": "USER 1"
}, {
    "GROUP": "GROUP_B",
    "SUBGROUP": "SUBGROUP B1",
    "USER": "USER 2"
}, {
    "GROUP": "GROUP_B",
    "SUBGROUP": "SUBGROUP B2",
    "USER": "USER 3"
}, {
    "GROUP": "GROUP_B",
    "SUBGROUP": "SUBGROUP B2",
    "USER": "USER 4"
}, {
    "GROUP": "GROUP_B",
    "SUBGROUP": "SUBGROUP B2",
    "USER": "USER 5"
}]

DataWeave转换将有效负载转换为如下结构的内容是什么样子的：

[   
    {
        "GROUP": "GROUP_A",
        "SUBGROUPS": [{
            "NAME": "SUBGROUP A1",
            "USERS": ["USER 1"]
        }]
    }, {
        "GROUP": "GROUP_B",
        "SUBGROUPS": [{
            "NAME": "SUBGROUP B1",
            "USERS": ["USER 1", "USER 2"]
        }, {
            "NAME": "SUBGROUP B2",
            "USERS": ["USER 3", "USER 4", "USER 5"]
        }]
    }

]

谢谢你的帮助

有关DataWeave开发，请参阅。在这种情况下，您可以参考“分组方式…”一节…。要转换上述消息，请尝试以下脚本：

%dw 1.0
%output application/json
---
payload groupBy $.GROUP pluck {
    GROUP: $$,
    SUBGROUPS: $ groupBy $.SUBGROUP pluck {
        NAME: $$,
        USERS: $.USER
    }
}
