Hi Richard,

Thanks for letting this public! I was reading through the document and one thing came up to my mind. About Exemplars:
CONSENSUS:  In-memory storage is acceptable for a first iteration.

Exemplars will be kept in-memory? I imagine that this will have a big impact if we expose a huge amount of exemplars, right? When instrumenting my app, should I do sampling with exemplars?

Kind regards,
Arthur

The plan for this stage is to have an in-memory ring buffer, so the storage space is bounded and also configurable. You shouldn't change anything about how you use examplars in your app for this.
