Gson Mapping Engine

[mbStavola]

I was wondering if there are any plans to add Gson as an object mapper?

The Jackson option is great, but it's kind of annoying to integrate KMongo with a codebase that already heavily relies on Gson (duplication of effort for serialization, two serde libs, et cetera).

There is no plan today to add Gson support.

For Jackson, bson4jackson is used under the hood for direct bson <-> object mapping.

I don't know any Gson lib with the same feature (direct bson support is needed, not JSONObject <-> Gson, because then there is a performance penalty). If this lib exists, it would be easy to add Gson support to KMongo.
