  Parsing gigabytes of JSON per second

  

• cbor-java

  8 95 5.1 Java

  Java implementation of RFC 7049: Concise Binary Object Representation (CBOR)

  JSON doesn't allow any custom type, so it is not "flexible" per se. Therefore you only need a format that supports the JSON data model and pretty much nothing else; CBOR [1] for example almost surely fits the bill.

  Cap'n Proto serialization/RPC system - core tools and C++ library

  

  I guess an example would be along the lines of protobufs, e.g. Cap’n Proto

  (which I have never used but really enjoy just for its charming website design alone)

• pronto

  0 6 0.0 Java

  Protobuf ORM (by CaperAi)

  

  I've written translation layers for such systems and it's not too bad. See this project from $job - 1: https://github.com/CaperAi/pronto

  It allowed us to have a single model for storage in the DB, for sending between services, and syncing to edge devices.

• simd-json

  Rust port of simdjson

  

• jsoniter

  2 1,443 0.0 Java

  jsoniter (json-iterator) is fast and flexible JSON parser available in Java and Go (by json-iterator)

  

  Protobuf parsing is slower than an optimized json library, e.g. https://jsoniter.com/
