simdjson : Parsing gigabytes of JSON per second

GitHub – simdjson/simdjson: Parsing gigabytes of JSON per second : used by Facebook/Meta Velox, the Node.js runtime, ClickHouse, WatermelonDB, Apache Doris, Milvus, StarRocks

JSON is everywhere on the Internet. Servers spend a *lot* of time parsing it. We need a fresh approach. The simdjson library uses commonly available SIMD instructions and microparallel algorithms to parse JSON 4x faster than RapidJSON and 25x faster than JSON for Modern C++.

• Fast: Over 4x faster than commonly used production-grade JSON parsers.
• Record Breaking Features: Minify JSON at 6 GB/s, validate UTF-8 at 13 GB/s, NDJSON at 3.5 GB/s.
• Easy: First-class, easy to use and carefully documented APIs.
• Strict: Full JSON and UTF-8 validation, lossless parsing. Performance with no compromises.
• Automatic: Selects a CPU-tailored parser at runtime. No configuration needed.
• Reliable: From memory allocation to error handling, simdjson’s design avoids surprises.
• Peer Reviewed: Our research appears in venues like VLDB Journal, Software: Practice and Experience.

This library is part of the Awesome Modern C++ list.
