Hello

I'm trying to create two events out of one so that the subsequent pipeline takes place in both.

The event itself, before the split happens here:

```auto
filter {
   if [type] == "pre-split" {
     mutate {
       replace => {"value_1" => "value_1_pre"}
       replace => {"value_2" => "value_2_pre"}
       replace => {"value_3" => "value_3_pre"}
       replace => {"value_4" => "value_4_pre"}
     }
   }
}

```

My idea is to separate this event into two, the first with the values 1 and 2 and the second with the values 3 and 4.

It is not clear to me if what I want is possible or if it is with the split filter that I have to do it.

I'm a bit stuck on this topic and a little help would be great for me. Thanks in advance!

A split filter is used to take each entry in an array and create an event for it. (It can also split a delimited string into an array and then do the same.)

I think what you want is a clone filter.

```
clone { clones => ["theClone"] }
if [type] == "theClone" {
    # Do one thing
} else {
    # Do another
}
```

Thanks @Badger !

So the idea would be something like this?

```auto
filter {
   
   if [type] == "pre-split" {
        
        mutate {
        replace => {"value_1" => "value_1_pre"}
        replace => {"value_2" => "value_2_pre"}
        replace => {"value_3" => "value_3_pre"}
        replace => {"value_4" => "value_4_pre"}
        }

        clone { clones => ["value12"] }

        if [type] == "value12" {
            mutate { remove_field => ["value_3_pre","value_4_pre"] }
        } else {
            mutate { type => "value34" }
            mutate { remove_field => ["value_1_pre","value_2_pre"] ​}
        }
    }
}

```

So I understand that the two "events" that have been generated from the original will be processed separately as shown in the following image?

I have made this drawing (sorry for my lack of artistics) that I don't know if it would help to understand what I want to do:

That looks right.
