QUESTION
I am struggling to wrap my head around the asyncio library. I thought you could simply define the sections of your code you want to run asynchronous, but in all the examples I have seen, people tend to define their main function as asynchronous. Here is the code that I have written:
...ANSWER
Answered 2020-Nov-03 at 02:44Couple of important things:
- Python interpreter GIL, runs on a single-thread; so technically you arent really running things in parallel
- But the catch is, most I/O operations 'hog' resources while your CPU during these periods is still idle. Thats where libraries like
asyncio
comes to your rescue. - They try to ensure minimal CPU-idle-time, by running other tasks in your queue while major I/O operations are awaiting their results
In your case, update_posts()
doesnt really seem like an async method in an ideal sense; because this method is technically only used to figure out which posts are to be downloaded and written
And since we are already discussing about download and writing, you can notice that you can actually make them run as independent tasks so ensure minimal downtime.
Here is how I might approach this:
