Comment:
Thank you Brian for the report! I agree that this is worth addressing, as
disk IO can indeed lead to stalls.
Careful consideration will be needed for how to handle the chunked file
writing without blocking the event loop. I'm wondering if we should have a
sort of abstraction for the chunked file writer and allow people to
override. Depending on the project's constraints or current dependencies,
some projects may choose to use a 3rd party library like
[https://github.com/alemigo/asynctempfile asynctempfile] (unclear whether
this is currently maintained), or Django channels, or something else?
We're open to a patch that addresses this while ensuring compatibility and
avoiding unintended regressions. Would you like to work on this?
(I'm torn whether to categorize this as Cleanup or New Feature, for now
I'm going with the former but we can adjust later on.)
