Requirement

We use MongoDB in our services and It'd be really neat to have MongoDB integrated as a supported storage backend.

Problem

Choosing other storage backends will add unnecessary complexity to applications by requiring of administrating additional databases just for the sake of storing traces.

Proposal

Add MongoDB as a supported storage backend. MongoDB supports TTL indexes and doesn't require a schema, integration with it can be easy and seamless!

Open questions

In the meantime, what can one do store traces in a MongoDB database?
