[SDK] arv-copy collection copy performance
I'm copying a pipeline with a 5990M collection. I noticed this code:
data = src_keep.get(word) dst_locator = dst_keep.put(data)
See attached image, there's a very clear falloff between blocks -- doing this sequentially isn't optimal. Download and upload could proceed concurrently. Also, it's possible we could get better utilization if we transferred multiple blocks at a time (e.g. 2x down / 2x up) by talking to multiple Keep servers. Consider a producer-consumer pattern using Python queues.
