MultiThreading in Python | Python Concurrent futures | ThreadPoolExecutor

Welcome to the video series on multithreading and multiprocessing in python programming language. In this video I'm talking about Python concurrent futures, which is an alternative way of doing multithreading and multi processing in python programming language.

The idea behind futures is not new and pretty much all programming languages have it in one way or others, but most of the time this topic is a bit confusing for the people. I've tried to make it simpler so that its easy for everyone to understand.

In this video, I've talked about creating multiple threads using ThreadPoolExecutor, I've talked about 3 way by which we can use the ThreadPoolExecutor to create multiple async tasks and take back the result from the async functions. I've also talked about using maps to put multiple async tasks

Hope this video will help you to understand concurrent future and you'll like this video.

Thanks for watching. Here are the contents of this video.

About Me i.e. An Insightful Techie

Greetings and Thanks a lot for checking out my YouTube Channel. I’m Deepak K Gupta (Daksh). This channel is a medium for me to share my learnings and journey as a Techie so that you not only learn from my experience but also from my mistakes

As a techie I am closely associated with software development, so most of my content will revolve around Programming Languages, AI, Machine learning and Databases. I share things which will help you learn, remember and use these things in an effective and efficient way.

As a Techie, I also know that there is a life beyond software development and it has a profound impact on our career as well as on our well being. I also share those learnings which I feel are worth sharing with the intention that it MAY help you in taking better decisions in your life.

Last but not the least, I'm a traveler and explorer by nature. I would like to take you with me on some of the interesting journeys around the world. Believe me there is more to learn outdoors than indoors

Hope you’ll like my contents and will be part of my journey 🙏

It is really a great explanation. Thankyou!

great thanks! However I'm not getting any output in the console from my .map functions! seems to work for you?

I have 2 procedures in the Postgres database that take 2 hours each to complete, but I want to run them parallelly without affecting any kind of db performance so that they both can finish in 2 hours and they are not dependent on each other. I have 4 cores allocated to that server.
if I run multiple procedures through concurrent.futures, will it be able to complete it in 2 hours?

Sir is it possible to apply multi threading in the same function, means if I consider a loop of 4 iteration and every iteration will be in different threads..as the data are not dependendent on the others.
