> +Question:+
> Can multiple fiware orion work with same mongodb backend?
> +Description:+
> I have tried connecting multiple orion instances from different machines to the same mongodb backend.
> The issue I have observed is that only one among the orion instances is able to process onchange subscription registered against attribute of an entity.
> My question is  - is it a valid practice of having multiple active instances of orion independantly handling incoming requests connected to the same mongodb backend. Does such a deployment configuration work in the same manner, in comparision to single instance of orion connected to mongodb backend.
> I have tried this with orion version 0.23 and mongodb version 3.4
