Hi all,

I'm trying to parse a json I get from an API which contains several lists of objects, which I would like to parse each object of each list to a different event.

```auto
{
   "Time":"XXXXX",
   "listA":[],
   "listB":[],
   "listC":[],
   "listD":[]
}

```

I've been playing with split filter, but what I get is 1 event with one object of each list:

```auto
input {
    XXXX
}
filter {
  json {
    source => "message"
  }
  split { 
    field => "listA"
  }
  split { 
    field => "listB"
  }
}
output {
    stdout {
        codec => rubydebug
    }
}

```

result event:

```auto
{
   "@timestamp":"2020-04-01T06:52:42.224Z",
   "objectA":{},
   "objectB":{},
}

```

What I would like to get are 2 different events:

```auto
{
   "@timestamp":"2020-04-01T06:52:42.224Z",
   "objectB":{}
}

{
   "@timestamp":"2020-04-01T06:52:42.224Z",
   "objectA":{}
}

```

Any idea how can I do this?

Thanks!

Create an array containing the list of lists and split that, then split each array within it.
