What do you mean by "worked well with logger/input outputs"? We could use (nested) tqdm
progress bars, which default to sys.stderr. @tschaume ?

Noting here that this enhancement could be a step towards @jdagdelen's suggestion of built-in profiling: because tqdm
reports seconds per iteration ("s/it"), one can profile Builder.process_item
performance this way.

Is there a way to do this automatically? I can see if get_items
is a list or a cursor it could work, but not if it's a generator, because we wouldn't know the total number of items?
from maggma.
Yeah, I was thinking of something along the lines of:
self.total_items = 23432
for i in items:
yield i
And it should build the appropriate tqdm progress bar.
Ideally it should detect what kind of env and use the right one as well.

What do you want as a best practice? A yield
, a cursor..?

from maggma.
Right. If there's no count, it would still be valuable to see it/s. I think the runner can try to call <obj>.count()
and then len(<obj>)
on what get_items()
returns (wrapping in a try/except) to pass the total=
kwarg to the tqdm constructor. I think it'd also be helpful for the runner to look for a Builder.total_items
set in the case of yield
ing.
