Piotr Nowojski commented on FLINK-8794:
---------------------------------------
[~Backlight]
3.What kind of downstream processor? Can not it just ignore the files with
"*pending" or "*in-progress" sufixes and "_" prefix?
I also don't think this is a bug, but designed feature (
https://issues.apache.org/jira/browse/FLINK-5054 ) of the BucketingSink. On the
other hand, we could change this behaviour/add an option for BucketingSink to
use temporary "in-progress" and "pending" directories instead of prefixes.
Also [~kkl0u] could you elaborate why rescaling forced us to keep lingering
files?
