[@haoyuwang5995]

I am confused about the definition of "FREE" around 24:30. Why the excutor have the ability to run the queued task when the coputation requirement are not satisfied. Also, I looked in the documentation, FREE is not mentioned in the TASK LIFECYCLE page. Is that a legit term or it is just a word for better understanding.

[@haoyuwang5995]

did you want to say that the FREE means that task get its turn to run but due to not enough resources it wait for more computation power and that distinguish this very task from other queued tasks.

[@KokkeOP]

@@haoyuwang5995 You can undeestand "FREE" as "now available". So if not involved in any computation, it is "now available" to proceed.

[@linorics]

Exactly what I was looking for. I appreciate the failures and fixing them. Very well done!

[@stumblinzz]

Thank you, this was responsibly informative. There was other sources of info I didn't even get as good of information when compared to this video. Simply put your video is really good! Thank you for making it.

Thank you for sharing the airflow concepts. Really helpful to get started. Referring to the documentation on the go felt great and realistic 😊

It might be better to start the tutorial with the "Intro part" (what is Airflow etc.) but in general I learned a lot, thanks!

Dear Course Instructor, I hope this message finds you well. I just wanted to take a moment to express my appreciation for your excellent course. It has been a fantastic learning experience, both educational and fun. However, I wanted to bring to your attention that some of the Python codes used in the course are no longer functional, which can cause some challenges for students trying to complete the course. As a result, I have some suggestions to make the experience even better. It would be fantastic if you could update the Python codes to reflect current practices and ensure they are functional. This would undoubtedly help students complete the course more efficiently and effectively. Thank you once again for offering such an exceptional course, and I look forward to seeing how it continues to evolve. Best regards,

[@coder2j]

Thanks for your comment. I think it is a super valid feedback. Let me check the GitHub repo and fix code which is not working. If you find anything is not working, feel free to share it with me. 🙌

Thanks for making the complete tutorial. I just finished watching it and learned alot

[@coder2j]

You are welcome 🤗

[@believethatyoucan92]

Just finished this tutorial, took me about a week plus I made changes to the dags to fully understand it. It is maybe a little bit outdated, I was running the latest version of airflow 2.6.3 but it is still a very good tutorial. The only real differences are tree view is deprecated. The only challenge I had here was using minio s3 as the s3 connection is also deprecated. I modified the code though to use azure blob storage instead and I’m pretty happy. Great tutorial, thank you for this. Also you’re at 5.9k liked where is the video on docker operator @coder2j ??

[@coder2j]

Thanks for your feedback. To get a better learning experience, it is suggested to use the same version as the videos. The Minio S3 deprecation has been covered in this follow up video: kzbin.info/www/bejne/qYexp3Sqfr-KmrM. Second bonus video is planned. Stay tuned! 🙌

Which demo are you following? I think you probably need to check the setup of the docker compose file. Here is the source code of my demo as a reference: github.com/coder2j/airflow-docker

[@vohoang6693]

Thank you for sharing free. This is the best airflow course I have leant. Everything is expressed fluently and easy to understand and practise quickly. This courage still working at airflow 2.9.2 - latest version at the time of this command except aws s3 connection (I must watch another video of you to update). I have a question about docker-compose file. What's different type of airflow executors at 13:30 and the purpose of the services you deleted in docker-compose file after that. That good be greet if you have some video to explain them.

[@coder2j]

That's how you configure airflow to run the workflows. Local executor is easy for demonstration, if your dag are computational intensive and lots of dags, you can consider running them in distributed manner, which is done by celery executor for example.

[@vohoang6693]

@@coder2j ​Thank for responding my question. I love distributed system and will try it if I have time. I also watch pyspark tutorial of you, it very clean for developer with pyspark. But that course practices with Spark standalone single node. I used Docker Compose to build a cluster to practice with that course and saveAsTextFile() is not recommanded because spark cluster and single node just processing your workflow and doesn't storage, orther thing is very fine. Love your channel after 2 tutorial clean, short and super easy practise. This is my docker-compose if you want to see version: '3.8' x-spark-common: &spark-common image: bitnami/spark:3.5.0 volumes: - ./notebooks:/home/jovyan/notebooks networks: - bigdata x-spark-worker: &spark-worker

Around 37:00 , where you create the multiple DAG versions, but dont create new files for them. Are they all saved? Or just displayed? I guess it isnt the convenient way to override old DAGs with new ones? Great tutorial so far!

[@coder2j]

The unique identifier of the dag is dag id. When the dag id is updated, the old dag version will be gone. Here just is displayed, it will not be scheduled or run anymore.

hi great author, i follow your steps from beginning. i have set the AIRFLOW_HOME and looks ok for this, but seems failed after airflow db init, could you please let me know? if i need to install db first or no? or do you have any suggestion? in minute 7:36 thank you so much broo

[@coder2j]

What error did you get? Did you use the same airflow version as that in the video?

[@coder2j]

If you are using windows, you need to use windows subsystem Linux or skip to install airflow using docker. Airflow doesn't work on windows natively

[@FewBreath]

[@deepankarthik4]

Wonderful tutorial. Clear explanation..

[@kabalchik5085]

I can't understand why we change the parameters(port to connection) of docker container with postgres which is inside our airflow app I thought that this container is for internal use like metadata etc. At 1:09:00 we created separate docker compose proj with another postgres container, what we are doing: expose existing db or connect new?

[@coder2j]

There are demo showing how to use airflow to get data from S3 and load into postgres db. I expose the postgres port for this purpose. If you use postgres only for airflow, then you don't need to expose the port doe external connection.

[@BOSS-AI-20]

what's the reason behind you're using LocalExecutor instead of celeryExecutor?

[@coder2j]

For the demo purposes, I want to keep it simple.
