Serializing JSON using streams

Symfony is able of encoding PHP data structures to JSON streams and decoding

JSON streams back into PHP data structures.

To do so, it relies on the JsonStreamer component, which is designed for high

efficiency and can process large JSON data incrementally without needing to

load the entire content into memory.

When deciding between the:doc:`Serializer component<serializer>` and the

JsonStreamer component, consider the following:

- **Serializer Component**: Ideal for scenarios requiring flexibility, such as

dynamically manipulating object shapes using normalizers and denormalizers,

or handling complex objects which multiple serialization representation.

Plus, it allows working with formats beyond JSON (and even with a custom

format of yours).

- **JsonStreamer Component**: Ideal for simple objects and tasks that

demand high performance and minimal memory usage. It's particularly

effective when processing very large JSON datasets or in scenarios that

require streaming JSON in real-time without loading the entire dataset

into memory.

Choosing between the two depends on your specific use case requirements.

The JsonStreamer component is tailored to optimize for performance and memory

efficiency, while the Serializer component offers flexibility and broader

format support.
