By Brian Labelle. Reduce allows us to iterate an array to accumulate a result. There are a few array operators like filter and map that do similar functions. You can use reduce to filter an array or map an array because you can reduce an array into another array but that wouldn’t be best practice. Ideally, you want to use reduce to produce a ....

This DataWeave example uses both the map and mapObject functions to iterate through the input and set all of the keys to upper case dataweave map array to object, Since HashMap implements Serializable and the constituent objects which are probably a Sting for key and an array for value are also Serializable, I think it is possible to store this.

In data processing, two of the most common collection data types are array (list) and map (HashMap). The key difference between a list and a map is how they are accessed. A list is accessed by an integer positional index, such as list. However, map is accessed by a key, such as map.getValue(“key1”) or simply [].
