Work Description: iemejia commented on pull request #13021:
URL: https://github.com/apache/beam/pull/13021#issuecomment-705822583
> @iemejia How the number of partitions is calculated different during the
SDF initial split then what we do with SourceRDD.
If I understood correctly the initial split is only of size 1 because it is
the full initial Source and then it divides further splitting based on the
Source split, isn't it? I still expected that the reshuffle would distribute
the work and we would end up with almost the same result after the subsequent
split. Or did I misread it?
