Hierarchical field sort with string interning

This blog post discusses a sophisticated solution for sorting fields in a heterogeneous record structure using string interning in C. It addresses a specific requirement to keep substructures contiguous in the JSON output while maintaining the original field order. The author provides a detailed technical approach involving token mapping and sorting algorithms, emphasizing efficiency and avoiding quadratic complexity. The implementation details, including code snippets, offer valuable insights into nuanced difficulties in software development related to JSON serialization.
