Asynchronous non blocking json parse not so fast

asynchronous non-blocking json parsing in python: a deep dive

this tutorial will guide you through asynchronous non-blocking json parsing in python, focusing on efficiency, responsiveness, and handling large json datasets without blocking the main thread. we'll explore why this approach is crucial, the tools available, and how to implement it with practical examples.

**why asynchronous non-blocking json parsing?**

in modern application development, particularly with web servers, apis, and data processing pipelines, speed and responsiveness are paramount. traditional synchronous operations can become bottlenecks, especially when dealing with:

* **large json files:** parsing multi-megabyte or gigabyte json files can take significant time, blocking the main thread and freezing the application.
* **high concurrency:** if multiple clients request json data simultaneously, synchronous parsing can lead to performance degradation and slow response times for all users.
* **io-bound operations:** waiting for the json data to be read from a network or disk can cause delays, impacting the overall user experience.

asynchronous non-blocking programming addresses these challenges by allowing the application to continue processing other tasks while waiting for the json parsing to complete in the background. this significantly improves responsiveness, scalability, and overall performance.

**key concepts**

1. **asynchronous programming:** asynchronous programming enables tasks to be executed out of order or concurrently, without blocking the main thread. it achieves concurrency through techniques like coroutines and event loops.
2. **non-blocking operations:** non-blocking operations initiate a task and return immediately without waiting for it to finish. they rely on callbacks or other mechanisms to notify the application when the task is complete.
3. **json parsing:** the process of converting a json (javascript object notation) string into a python data structu ...
