I have a scenario where one user would like to play game with someone random online.
Here are basic requirements

• select one random user
• send a request to that user via channel
• if user doesnt respond within 10 seconds, try to connect to other user
• if user accepts within 10 seconds, stop sending requests and start the game
• if user rejects the game request, lets say after 2 seconds search for another user

Here is what I have tried:

• I start a task ie Task.async -> search_palyer end
• search_palyer will first check if the last request was accepted or rejected
• if last request was not accepted, it will fetch another random player and send request
• called timer.sleep for 10 seconds
• recursive call to same function untill it succeeds

This works but the problem is, if the palyer to which I send request rejects immediately my task will sit idle for 9-10 seconds and wont do anything. I want to find player as soon as possible. Player gets a bad experience this way as he/she has to wait longer
