PyCon UK 2023

API performance is crucial for delivering a smooth and responsive user
experience. GraphQL has gained popularity as a flexible and efficient query
language, but without proper optimization, it may underperform or even become a
bottleneck in your application.

In this talk, we'll dive into the essential techniques and best practices to
optimize GraphQL performance, ensuring that your APIs are snappy, scalable, and
resource-efficient. Attendees will learn:

• The importance of batching queries and how to implement it using DataLoader or
  similar libraries.
• The concept of query complexity and depth, and how to set up limits to prevent
  resource abuse.
• Leveraging persisted queries to reduce network overhead and improve caching
  capabilities.
• Implementing caching strategies, both on the server and client-side, to
  minimize redundant requests and reduce load times.
• Exploring monitoring and observability tools that can help you identify
  performance bottlenecks and continuously optimize your GraphQL implementation
  for maximum efficiency.
