Queue of jobs with max concurrency
aiqc opened this issue · 1 comments
I have hundreds of jobs to run, but my server only has enough resources to run 5 jobs at a time.
It would be nice to create a queue of jobs where 5 are always running.
For context, it's all the same task/logic, just for a different input file.
How do I solve my problem right now?
I have a CSV file that keeps track of which files have/haven't been processed. I run a notebook that fetches 5 unprocessed files and feeds them through a series of multiprocessing Pools. It works, but I wouldn't want the entire queue of jobs in a while loop in case a job fails. So I have to check back every few hours and I am missing out on the chance to launch jobs while I sleep.
Looks like the airflow parity is
max_active_runs_per_dag
