msgpack

Converts Python objects into a compact binary format, offering significant speed and size advantages over JSON, as highlighted in the project description for data-intensive applications.

Enables seamless data exchange with other programming languages that support MessagePack, facilitating interoperability in polyglot systems without format conversion hassles.

Allows packing and unpacking of custom data types like datetime using default and hook functions, demonstrated in the README with practical examples for real-world use cases.

Includes the Unpacker class for processing multiple objects from continuous streams, useful for real-time data applications as shown in the streaming example.

Provides configurable options such as max_buffer_size and strict_map_key to mitigate risks when handling untrusted data, addressing common security concerns in serialization.
