Java ExecutorService - Part 1 - Introduction

[@fazilkhan6779]

This executor service series is one of the best ever educational KZbin series ever. Thanks a ton. Your explanation is awesome.

[@mostinho7]

Done thanks Thread pool instead of creating a 1000 threads which is expensive, can make a fixed size pool and submit 1000 tasks to it. 3:40 how it works internally 5:30 ideal pool size for cpu task is number of cores 9:30 thread pool size for io intensive tasks

[@ramcorp542]

Thank you, you have a skill for explaining complex concepts in a clear concise manner. I would love to see full fledged courses created by you.

[@AyushSharma-ux4fk]

A very intelligent statement. If your tasks are I/O intensive e.g. DB calls, Network calls. Most of the threads would be in waiting state (waiting for DB response or Network call response) in such a scenario having a large thread pool is the right way to go. That way you would be able to start more tasks. Thanks

[@yathiraju1000]

Guys please share his videos in other groups. we have to support this kind of content and it will be very useful to people who are looking for good content

[@amritasahoo6773]

Really explained well. This is the best I have found till now. Thank you. Keep up the good work :)

[@DefogTech]

Thank you for the kind words!!

[@yathiraju1000]

Yes this guy is awesome in subject and the way he is describing the concepts are speechless . I heard few concepts and all are above the notch.

[@orangefield2308]

best work ever, please make more videos !! I understand executorService finally

[@MrSN99]

as i'm kotlin dev i just skipped this completely. But you explaining this made some things clearer. I didn't expect this.

[@shivshaktipandey7148]

explaining with how , why , what , when -------------- everything about the topic -------- hats off ----------- u will complete 100k soon bro

[@ankitnavalakha508]

There are so many videos for multithreading available in KZbin but I found you best because of your diagram presentation which is unique. You explained very well. You are awesome and continue with this key feature.

[@sharatchandra9198]

I have read so many places, everything is of no use, you are brilliant.

[@manish436]

Really great explanation, adding one formula for I/O intensive task, according to "Java Concurrency in Practice" Number of threads = Number of Available Cores * (1 + Wait time / Service time)

[@divyamahesh9032]

You know while I start the interview preparation I'm watching all these videos saved , and this is my 3rd time watching it while I'm moving out of my 2nd company....🎉🎉 Thanks for your great work .

[@DefogTech]

That's so heartening to hear! Thank you for the kind words. Good luck for the new job. Wish you great success there as well.

[@jaleelpasha3301]

Introduction: - The video discusses the concept of thread pools and the Java `ExecutorService`. - It explains how to efficiently manage tasks using a fixed number of threads. Key Points: - In Java, running tasks asynchronously is straightforward using threads. - Tasks can be executed synchronously by creating a class that implements `Runnable` and overriding the `run` method. - A new thread can be created with an instance of this class and started. - To run multiple tasks, one could use a loop to create and start new threads for each task. - However, creating too many threads can be inefficient as each thread corresponds to an operating system thread. - To address this, a thread pool can be used to manage a fixed number of threads. - Tasks can then be submitted to the thread pool, and the threads in the pool pick up and execute these tasks. - Using a thread pool reduces the overhead of creating and managing threads, improving performance. - The ideal pool size depends on factors like CPU-intensive or IO-intensive tasks. - For CPU-intensive tasks, the ideal pool size is the number of CPU cores. - For IO-intensive tasks, a larger pool size may be beneficial to handle waiting states effectively. Conclusion: - Choosing the right pool size for thread pools is crucial for optimal performance. - Understanding the nature of tasks helps determine the appropriate pool size. - Java provides the `ExecutorService` interface for managing thread pools, offering flexibility and efficiency in task execution.

[@sekharsoftware]

Really precise to the point and very useful. You should do a podcast.

[@shubhamjain2810]

Your way of explaining the topics are really good. I am having one question. It might be stupid one,but I wants to know How to handle the Atomicity for write and Read operation in Such case. Pool size is of 20. t1 to t20 are doing write operation. ---> They will be in waiting state t21 to t30 are doing Read operation. ---> In between any of this thread comes in and start reading and get response before completion of write operation of all 20 threads . It may get old data.

Thanks a lot, very well explained .I feel one of the best video so far compare others on youtube

[@flywithashutosh4772]

Why so less subscriber to such a beautiful channel , great work dude keep it up.

[@DefogTech]

Thanks buddy!

[@dvoulio]

Guys.... the absolutely most crystal clear explanation of Thread Pools I have ever heard. Beautifully sparse, no-noise or arm waving... well-presented and recorded. Bravo... I have become a great fan and are convincing others as well !! One small request... what is the cursor enhancing software you are using in the presentation ???

[@DefogTech]

It's pointer function in Google Slides. Thank you so much for the kind words BTW! Means a lot to me

[@derrick3534]

Wow way better than the Udemy tutorial on Executors. You should expand on this and make a Udemy tutorial. Great teaching skills.

[@DefogTech]

Thank you! My long term plan is to create my own site like egghead.io , let's see how that goes.

[@mikeprice7942]

You explain this topic very well! Appreciate the visualization!

[@kamleshpar9847]

Very well explained , pl continue your excellent work

[@marshalkiruba]

Loved the explanation. Just a lame question. For a CPU intense operation, shouldn't the ideal thread pool size be (no of cores-1) as there is already a main thread running?

[@rizwansayyed7893]

i really would like to know this

[@HussainMohammedAshruf]

@@rizwansayyed7893 main thread dies soon, before other threads!

[@rizwansayyed7893]

@@HussainMohammedAshruf i don't understand does main thread count in cpu runtime cores available

How I wish to add the new Java 8's newWorkStealingPools() method Thanks :)

[@milankushwah8580]

🎯 Key Takeaways for quick navigation: 00:00 *Running tasks asynchronously in Java traditionally involves creating new threads manually.* 02:30 *Utilizing a thread pool with a fixed number of threads is more efficient than creating threads dynamically, especially for large numbers of tasks.* 04:32 *The ideal pool size depends on the nature of tasks; for CPU-intensive tasks, match the pool size to the number of CPU cores, while for IO-intensive tasks, a larger pool may be beneficial.* 08:44 *Considerations for CPU availability in multi-tasking environments and balancing thread pool size based on task submission rate and IO operation wait times are crucial for optimizing performance.*

[@viveksingh-rt4py]

Thanks a ton for sharing the video. Clear and concise explanation. May I ask you one question. Say If I have multi core processor and I have initialised ExecutorService with pool size as 100, all my task are IO intensive. Scheduler will make use of all core and will execute threads on different core. Is my understanding right.
