Re: Advice on parallelizing network calls in DoFn


I'd just like to close the loop. Josh, did you get an answer/guidance on how to proceed with your pipeline?
Or maybe we'll need a new thread to figure that out : )

Hello all:

Our team has a pipeline that make external network calls. These pipelines are currently super slow, and the hypothesis is that they are slow because we are not threading for our network calls. The github issue below provides some discussion around this:


In beam 1.0, there was IntraBundleParallelization, which helped with this. However, this was removed because it didn't comply with a few BEAM paradigms. 

Questions going forward:

What is advised for jobs that make blocking network calls? It seems bundling the elements into groups of size X prior to passing to the DoFn, and managing the threading within the function might work. thoughts?
Are these types of jobs even suitable for beam?
Are there any plans to develop features that help with this?

Thanks
