I have a neat trick which can pull you out of this situation almost always and the best part is we don’t have to scrape. In fact, it is better to first try & implement this trick before trying out web-scraping.

Airflow has an Operator called “Kubernetes Pod Operator” which would ideally connect to a cluster, create a pod run the desired program and delete the pod. This is a much-required feature where we will be able to run our post-load/Intermediate jobs or process in the Kubernetes cluster which can scale up and wide. This saves a lot in terms of cost as the pods will be up only when we are running the job. …

Wouldn’t it be cool if you can speed up your program by just adding a decorator to the function? Wouldn’t it be cool if you don’t have to worry about running the data in a list as a parallelly?

Today we are going to write a python decorator which exactly does these automatically for you, so that you can concentrate more on the logics of your code than worrying about multi-threading issues.

Some basics on python multi-threading before we start.

  1. The best place to implement it is where the function that we are trying to parallelize is IO heavy (the…
