Agenda 📢
We have a great line-up ready, the agenda of this GraphQL meetup:

• 17:30-18:15 Food/drinks + network
• 18:15-18:30 Welcome & Announcements by An Ngo (bol, GraphQLConf'25 committee member)
• 18:30-19:00 Visualizing GraphQL: Trends & Deprecation Insights by Val Nesterov (Sytac, Albert Heijn)
  GraphQL provides flexibility, but managing its evolving schema and client usage can be challenging. In this talk, we’ll explore how to build custom dashboards tailored for developers, focusing on key insights like tracking deprecated queries and visualizing API usage across clients.
• 19:00-19:30 GraphQL nullability: past, present and future(s)?! by Martin Bonnin (Apollo, GraphQL TSC member)
  Since its inception in 2015, GraphQL has a strong type system that includes nullability.
  In the last 10 years, the programming language landscape has changed considerably though and the defaults from 2015 are becoming harder and harder to work with.
  In this talk, we'll take a look at the reasons why the GraphQL nullability is the way it is, what problems it causes today, possible solutions you can already use and other solutions that will require more changes to the language.
  Let's improve the GraphQL type system together!
• 19:30-20:00 Schema Defined Rate Limiting by Minghe Huang (Booking.com)
  At Booking.com we process billions of GraphQL requests per day, in order to ensure we provide a stable experience for our customers and our subgraphs we have introduced a custom @rateLimit directive to enable subgraphs owners to define rate limiting down to the field level. This approach provides an enforcement mechanism at the gateway level making it seamless for teams to adopt the benefits without reworking their service.
• 20:00-end drinks + network
