Uri Goldshtein discussed how Hasura's remote joins feature and GraphQL Mesh can be used to create data graphs. He explained that the combination of these tools allows for fast-paced application development in enterprise environments, as well as integration with other sources such as third-party APIs. GraphQL Mesh is a tool that takes any source and converts it into an executable GraphQL schema, which can then be run as a gateway or SDK on existing services. This enables the creation of a cohesive platform for data management and integration.
