Add metadata to Client in client.py and read it inside server.py

[fredowashere]

We are making ready-to-run client.py files on for our users and we have certain properties we would like to read inside the server.py.

Is it possible, and if so how, to define arbitrary metadata for each client.py file and to read this data inside the server.py?

Hey @fredowashere, if your clients have that metadata built-in when the client object is created, then the server can request that data using the get_properties() method. Alternatively you can share that metadata with the server via the last return argument in the client's fit() method. That argument is internally called "metrics". Then, in your strategy you'll be able to process (in the aggregate_fit() method) them the way you want.
