Hello, I'm using Logstash to read external REST API and feed elastic search. the API data looks like this:

```auto
{
    ArrayOfParent: [
    Parent: {
    ArrayOfChildTypeOne: [
    {ID: 1, Name: child1}
    ],
    ArrayOfChildTypeTwo: [
    {ID: 2, Name: child2}
    ],
    ArrayOfChildTypeThree: [
    {ID: 3, Name: child3}
    ]
    }
    ]
} 

```

My aim is to save the parent as a separate document and each child as a separate document as well, let's say the output should look like:

- Doc1: parent
- Doc2: child1
- Doc3:child2
- Doc4:child3

How can I do this in logstash? is there a better tool than logstash for this?

Thank you!
