QUESTION
I have been tasked lately, to ingest JSON responses onto Databricks Delta-lake. I have to hit the REST API endpoint URL 6500 times with different parameters and pull the responses.
I have tried two modules, ThreadPool and Pool from the multiprocessing library, to make each execution a little quicker.
ThreadPool:
- How to choose the number of threads for ThreadPool, when the Azure Databricks cluster is set to autoscale from 2 to 13 worker nodes?
Right now, I've set n_pool = multiprocessing.cpu_count(), will it make any difference, if the cluster auto-scales?
Pool
- When I use Pool to use processors instead of threads. I see the following errors randomly on each execution. Well, I understand from the error that Spark Session/Conf is missing and I need to set it from each process. But I am on Databricks with default spark session enabled, then why do I see these errors.
