Msgspec Vs Orjson. msgspec may be used for serialization alone, as a faster JSON or
msgspec may be used for serialization alone, as a faster JSON or MessagePack library. It is the fastest python library for json encoding & decoding. For supported When used without schemas, msgspec is on-par with orjson (the next fastest JSON library). time datetime. For the greatest benefit though, we recommend using msgspec to handle the full serialization & Achieving Significant 80%+ Performance Improvements in Data Validation: Msgspec vs. Pydantic (Python Programming) In the realm of Python In the JSON schema produced from a msgspec Struct, I'm wanting to output to the schema some text descriptions of the properties held within the Struct in the same way as the docstring of the It seems the orjson. msgpack. g. Search For Python Packages Get to know about a Python package or Compare Python packages download counts and their Github statistics orjson msgspec Maximum of 5 packages msgspec's decoding is significantly faster than ORJSON and the standard library's JSON module, boasting up to 150x faster performance compared to Pydantic V1 and 10-20x faster than Pydantic V2. msgspec has additional features, like encoding, MessagePack support (a faster alternative format to JSON), and more. UUID While orjson is faster than json and ujson, the difference between them is only ~10% at most. This shows that msgspec is able to decode JSON faster when a schema is provided. Orjson turned out to be the fastest library in absolutely every benchmark, across all Python versions. with fields defined via a TypedDict), therefore it If you work with a large datasets in json inside your python code, then you might want to try using 3rd party libraries like ujson and orjson Compare orjson, msgspec, pydanticNo Getting Started Articles Yet Click here to contribute to learn-pip-trends. I will have to give msgspec another go because that was much more efficient loading but Msgspec types msgspec. Raw msgspec. timedelta uuid. Struct types Standard Library Types datetime. orjson - Extremely fast Rust-based library with rich type support. Superior Performance Benchmarks msgspec's decoding is significantly faster than ORJSON and the standard library's JSON module, Although I only tested one example doc, is seems that (1) libpy_simdjson is not fully baked, so use pysimdjson instead; (2) simdjson could ujson - Fast C-based JSON parser; a drop-in replacement for json. UNSET msgspec. If you’re parsing JSON msgspec is designed to be as performant as possible, while retaining some of the nicities of validation libraries like pydantic. It benchmarks as the fastest Python library for JSON and is more correct than the standard json library or The fashionable orjson and msgspec libraries differ slightly from the standard and ujson libraries in the way they implement the dumps function: it returns bytes directly instead of a str object orjson is a fast, correct JSON library for Python. It serializes dataclass, datetime, numpy, and UUID instances natively. loads is very cpu intensive and my own parsing is not as bad as I thought. datetime datetime. date datetime. For supported types, Search For Python Packages Get to know about a Python package or Compare Python packages download counts and their Github statistics orjson msgspec Maximum of 5 packages msgspec can serialize/deserialize JSON as fast (and frequently faster) as orjson, while also type checking the message and converting it into nice native python types. I personally like to use orjson when working with fastAPI as it has builtin support for orjson response format making it a more developer When benchmarking individual types for the core parsing routines, msgspec 's float parser is known to be a bit slower (~15% slower) than orjson's, while the other core type parsing routines msgspec is designed to be as performant as possible, while retaining some of the nicities of validation libraries like pydantic. Orjson beats every other library, in both msgspec on GitHub msgspec on PyPI msgspec on Conda Forge 2. I maintain msgspec [1], another Python JSON validation library. Creating python objects dominates the execution time of any well optimized decoding library - Thank you for your work! Can we please make orjson dependency optional? I have concerns about the quality of this dependency (compatibility, security) and would prefer to not use it . Ext msgspec. Pydantic V1 was ~100x slower at encoding/decoding/validating JSON than msgspec, which was more a testament to Pydantic's This guide explores how to achieve the fastest JSON parser Python, comparing built-in json solutions with powerful external libraries like orjson and msgspec, and providing ‘how-to’ examples for The top contendors are orjson and msgspec (duh). com 先后尝试过不同的 json 库，包括不限于以下选手： orjson/ujson/rapidjson/simplejson，基本的对比效果就是：序列化各种吊打内置 orjson is a fast, correct JSON library for Python. rapidjson - Python wrapper for RapidJSON (C++); good It looks like msgspec. Struct is the fundamental base type for msgspec which is built in C, the equivalent in pydantic-core is really a dict (e.
