Subject Re: Naming files while saving a Dataframe
Date Sat, 17 Jul 2021 16:39:04 GMT
Reason we've two jobs writing to the same directory is that the data is
partitioned by 'day' (yyyymmdd) but the job runs hourly. Maybe the only way
to do this is to create an hourly partition (/yyyymmdd/hh). Is that the
only way to solve this?
