How can we achieve a similar functionality when designing our gRPC APIs? A production contains multiple fields such as: title, format, schedule dates, scripts aka screenplay, budgets, episodes, etc, but let’s keep this example simple and focus on filtering out schedule dates and scripts when requesting a production.
