**Original Question:**  
Hi. I would like to set the local batch size for each of my clients from the server. Currently i batch the data before as part of my client init. Is there a way to get config data from the server at this stage, without having to wait until the client calls fit ?  
Cheers,

**Answer:**  
Hi. Do you have a custom strategy and a custom client class?  
Currently, configs can only be sent to client by `Strategy.configure_fit` or `Strategy.configure_evaluate` . The server can store arbitrary configs in the instructions obtained from `Strategy` and send them to clients in the first fit round. I am not exactly sure what functionalities you want to implement but normally you can get the configs as an argument in `Client.fit` method.
