The Sched app allows you to build your schedule but is not a substitute for your event registration. You must be registered for GraphQLConf 2025 to participate in the sessions.
Please note: This schedule is automatically displayed in Central European Summer Time (UTC+2). To see the schedule in your preferred timezone, please select from the drop-down located at the bottom of the menu to the right.
IMPORTANT NOTE: Timing of sessions and room locations are subject to change.
Sign up or log in to add sessions to your schedule and sync them to your phone or calendar.
@defer allows you to specify which parts of your operation are urgent, and which can be delayed. However, there is still a contract with @defer: all your data will always be returned, at some later point.
This poses a problem for certain classes of product: if only 10% of your operation will ever be on consumed, but you don't know exactly which 10% that will be, defer can introduce substantial hidden costs. To improve performance and reduce compute costs, Meta created @async to ensure products only ask for data when it's needed.
