[Feature request] Controling the number of thread being used

[kirianguiller]

Hello the ungoliant team,

I would like to know if it's possible to have as a parameter the number of thread that we would like to use for a given step? (for instance the pipeline step). By default, if the parameter is not provided, it would use all the thread, and if a number of thread, below the number of available of thread of the machine, is provided, it would only use this number ?

Thanks a lot !!

Since ungoliant uses rayon as a library for easy parallel programming, you can use an environment variable setting the number of (logical) threads used by the program.

As an example, using RAYON_NUM_THREADS=1 ungoliant pipeline .....will limit the number of threads to 1.

I'll add a -J in the next release so that the setting is more ergonomic.

Thank you for the report :)

Thank you so much @Uinelj ! It's really helpful. I will use the env variable export for now then :).
Do you want I close the issue ? Or maybe you want to wait to have the -J implemented in the next release before closing the request ?

Thanks again !

I'll use the issue to track the implementaton of the feature :)
