Hi,

there is a fork of the mongo river project that adds this feature:

> **[GitHub - gustavocoding/elasticsearch-river-mongodb: MongoDB River Plugin for...](https://github.com/gustavocoding/elasticsearch-river-mongodb)**

> MongoDB River Plugin for ElasticSearch. Contribute to gustavocoding/elasticsearch-river-mongodb development by creating an account on GitHub.

Mapping capabilities are described in the documentation.
