Hi @luzhzhsoft and welcome 🙂

`elasticsearch` output in libbeat doesn't currently support the `join` datatype.  
You can set the ID of the documents using the `event.SetID(string)` method, and you can also add the fields, but there is no way to set the routing.

I was going to suggest you to create a new issue, but I see that you have already created one 🙂
