DGS: How Netflix handles high-volume traffic with Spring Boot

What is the NETFLIX-DGS framework?

1⃣ Spring Boot-based GraphQL framework developed and used directly by Netflix

2⃣ It was created to overcome the problems of existing REST APIs and to operate GraphQL optimally in a microservice environment .

3⃣ This is a framework developed with a focus on efficient productivity of developers.

4⃣ DGS is used in hundreds of services within Netflix, and is a proven technology in practice .

5⃣ Supports GraphQL Federation , providing excellent scalability even in large-scale systems.

6⃣ Netflix's Java Platform team is continuously developing and optimizing it , and it is now open source. 🚀

How NETFLIX Handles High-Volume Traffic Efficiently with Spring Boot

NETFLIX developed the DGS framework through this process.

• In 2018, NETFLIX explored the use of GraphQL to solve problems in operating REST APIs.

• Starting to introduce GraphQL to some services in 2019

• Designing the DGS framework to enable more efficient GraphQL development in 2020

• In 2021, the DGS framework, which was used internally, was released as open source.

• As of 2022, NETFLIX is operating hundreds of internal services with DGS and plans to continuously improve them.

Close collaboration between NETFLIX and the Spring team results in the release of version 10.x!

In March 2024, NETFLIX announced the integration of DGS and Spring for GraphQL in close collaboration with the Spring team.
The unification plan is scheduled to end in late 2024, and the unification was released as version 10.x on December 21, 2024!

This version removes all existing legacy modules and code, significantly reducing the size of the codebase.

This is expected to contribute to accelerating future function development .

And it has gone through performance optimization work , so developers can now develop more efficiently .

This course will help you implement the technologies adopted by NETFLIX into your own service !

The lecture covers only the basic usage of DGS in the most concise manner possible.

You may think that the lecture time is short to learn one skill, but I edited out all the unnecessary content and meaningless time from the video, leaving only the parts that I thought were necessary.

You can quickly acquire skills through the experience of developing small services yourself !

In this lecture, we will develop a virtual movie search platform, moview service, using DGS.

Through these experiences, you can quickly acquire skills and get a feel for applying them to practice!
