Great explanation! I still wonder how the PythonOperator would be able to make an instance of a python class and call a specific method of that class. Most of the videos I have found only seem to showcase the use of functions for the python_callable param. 🤔

Hello, I am new at apache airflow. Your videos of airflow are awesome and helped me to understand it. I have a request to you, I don't know is it possible to use airflow for php application Cron task. If yes, then it would be a great help for us if you make a video on it step by step like other videos.

I'm new with airflow..... currently I have a server with jupyterhub+jupyterlab...I've installed airflow at the same server and I wanted to create this DAG from jupyterlab... but I don't have visibility of airflow modules within jupyter environmente despite of they are installed at the same server... How can i proceed?... and leads me to this question, where should I build one dag? what's your suggestion?
@RajeshSamson 2 роки тому
How you are able to get suggestions in your VSC without installing the Airflow dependencies?

Marc, I stuck with an issue. I am trying to create multiple dagRun with same execution time, but getting exception. To overcome this, i tried to create it with microsecond precision, but still dagRuns are using "seconds" and truncating the microseconds. I also tried "replace_microseconds"=false, but no success. Please help or if you know any doc, please share.

How did you submit your script to Airflow? Only then you'll be able to view it in Web UI right?

Excellent tutorial! Just one question: is there any particular reason to use functions with an underscore, like "_training_model" instead of just "training_model"?
@divyanethikopula4171 2 роки тому
"_" is usually used to indicate that this function belongs to same file.
@sagarkharab 2 роки тому
It's an indication that this is an private function or for internal use only.

Hi Marc, Awesome lecture. Though I have a small doubt. Lets say I am currently working on Azure cloud. I am using databricks jobs for my ETL. Then why should I learn airflow if I can schedule my job dependencies using Azure data factory? What are the advantages over other data integration tool? I am confused about this one thing.
@namanmehta4658 Рік тому
It's not only about ADF or airflow, there are hundereds of scheduling/orchestration tools out there. You need to see which one works for you. Your question can be rephrased as we already have IBM cloud and AWS, why do we need Azure. The simple thing to understand is that every tool/service provides features, you need to cehck which one works for you. One way to go is, do some research, read few articles. What I would recommend is, read about few tools, choose 2 best tools based on features they provide, take 5 days, work on 2 POCs around your use case, weigh the pros and cons, you should have better understanding. There can be other factors depending upon the company/institute you are at, if you require good prompt support, the associated cost etc. Go for the research, try POCs and make an informed decision. Don't be afraid to make mistakes, that's how we all learn.
@namanmehta4658 Рік тому
I forgot to tag the link in the above message(PS:I have no idea about ETL or ADF) www.elixirdata.com/blog/azure-data-factory-vs-apache-airflow#:~:text=Azure%20Data%20Factory%3A%20It%20supports,directed%20acyclic%20graphs%20of%20tasks.
@dataaholic 2 роки тому
In Function, _choose_best_model return "accurate" . How does the python/airflow know that "accurate" is not a string but a task_id for BashOperator ?
@BigJoenads 2 роки тому
It won't be python that "knows", it will be what airflow is doing behind the scenes. Since he's specified it as a python_callable, I imagine airflow will call the function and respond to it's return appropriately.
@kirby900 3 роки тому
Marc, I reproduced the example you demonstrated, but I notice strange behavior: when the function fetches results from the training runs, the results are the same each time I run the DAG, so the same branch is always taken. It seems like the training function result gets cached and re-used. Any idea why?
@kirby900 3 роки тому
Update: I added a call to random.seed() in the _training_model function, and it resolved the problem.
