The Correct Approach: Return the Updated Value The standard and correct way to handle this is to embrace the client-server nature of gRPC. The plugin (exec2) should perform its logic and then *return the modified data* back to the main application (exec1).
The workflow should be: 1. *exec1 (Client):* Calls a gRPC function on exec2, passing the current state of the item in the request. 2. *exec2 (Server):* Receives the item (as a copy), performs its updates on that copy. 3. *exec2 (Server):* Returns the fully updated item in the gRPC response. 4. *exec1 (Client):* Receives the response and updates its original item with the returned data.
