Daniel Lemire's blog discusses the challenges and advancements in handling JSON data in C++. JSON is widely used for data representation, but its processing can be slow, particularly in C++. Existing libraries like simdjson have improved speed, allowing for gigabytes per second processing. However, developers still face hurdles in mapping JSON to C++ structures efficiently. The upcoming C++26 standard introduces powerful reflection capabilities, which will enable automatic serialization and deserialization of data structures, significantly simplifying the process for programmers. This feature will allow C++ to generate fast and safe code at compile time, addressing the current need for custom functions to handle JSON. Lemire's benchmarks demonstrate that the new C++26 serializer can outperform existing libraries, achieving speeds of up to 1900 MB/s compared to 100 MB/s with nlohmann/json for Twitter data serialization. This advancement is expected to have a profound impact on C++ programming, making it more competitive with other languages that already support reflection.
- JSON processing in C++ is currently slow and requires custom code for serialization/deserialization.
- C++26 will introduce powerful reflection, automating JSON handling and improving performance.
- Benchmarks show the new C++26 serializer significantly outperforms existing libraries.
- The upcoming features are expected to simplify programming and enhance C++'s competitiveness.
- Reflection in C++26 is anticipated to be a major advancement since C++98.
