Can I do parent-child mappings using elaster?

@alexbeletsky
If I have a field in a mongodb collection, can I feed this as a parent_id, as per the bulk API, and push the rest of the fields to a documents in elasticsearch using elaster? If so, would you be able to give me the right form of the configuration?
I see you mention highland.js in one of your other issues. If this might be an alternative tool to getting this done, would you be able to point me to a working example?
Many thanks for your input.

@Analect parent-child mapping is not supported at the moment. Feel free to submit PR, is you came up with some solution.
