Get object by value

Technical Discussion
#1

Hi all. Apologies if there is an obvious answer, new to all this.

Looking through the documentation, examples and other implementations, it seems that the way to get objects is by Address/ID after sending a list of objects that exist, and I understand the reasoning for this.

I am wondering how this scales if you have potentially thousands or more objects needing to be referenced, and if there is a way I could for example, get the profile of a user by their username, rather than by their Address/ID.

Thanks.

It is possible, like this. But you need to link both the value and the address at the app level, somehow. This will be different for every kind of link in your happ.
