Vk bot in python, for large-scale application?

Question

Python

I have such a task, to make a bot for the institute group, I will write in python, the bot performs simple functions (show this, show this, schedule, pairs, marks, news and everything in principle) The written prototype would have already gone into business if it weren’t for one but. The group is used daily by 100 to 3000 people. The bot will stupidly not have time to answer everyone. I was offered to see some kind of katun engine (I don’t remember honestly), it performs asynchrony. But I didn't figure it out. I decided to turn to you, how to solve the problem of blocking a large number of users on the bot?
(ps I use the vk_api library, python version 3.7.3)

Answer 1

The group is used daily by 100 to 3000 people

It's not an indicator at all. Of these 100-3000, how many will actively write to the bot and with what frequency?
If your bot is designed just for a hi-response, then there will be no problems.
If you are still very worried that there may be problems, then use aiovk instead of vk_api.
