Using asynchronous programming for responsive systems
With multiprocessing and multithreaded programming, we were mostly dealing with synchronous programming, where we request something and wait for the response to be received before we move to the next block of code. If any context switching is applied, it is provided by the operating system. Asynchronous programming in Python is different mainly in the following two aspects:
- The tasks are to be created for asynchronous execution. This means the parent caller does not have to wait for the response from another process. The process will respond to the caller once it finishes the execution.
- The operating system is no longer managing the context switching between the processes and the threads. The asynchronous program will be given only a single thread in a process, but we can do multiple things with it. In this style of execution, every process or task voluntarily releases control whenever it is idle or waiting for another...
