Q50: What is Just-In-Time (JIT) GraphQL Execution (e.g., `graphql-jit`)?
Standard graphql-js dynamically parses and interprets AST nodes on every incoming query. JIT engines compile incoming GraphQL documents into optimized, direct JavaScript V8 functions upon first receipt. Subsequent executions call these compiled functions directly, improving throughput up to 10-15x.
Key Takeaways
- JIT compilation translates GraphQL query ASTs directly into optimized JavaScript functions.
- It eliminates AST traversal overhead for high-throughput production services.
