>    Affects Versions: 2.2.0
>            Reporter: Gopal V
>            Assignee: Gopal V
>            Priority: Minor

>
> The CUSTOM_SIMPLE_EDGE impl has differences between the size constraints of either edge
which cannot be represented by the ShuffleVertexManager presently.
> Reducing the width based on the hashtable build side vs the streaming probe side have
different consequences since there is no order of runtime between them.
> Until the two parent vertices of the shuffle hash-join are related, this feature causes
massive inconsistency of performance across runs.
> For inner & semi joins, the hashtable side should have a higher priority than the
streaming side and for left outer joins, the streaming side can over-take the hashtable side,
being the more dominant factor in the final row-counts.
> Until such priorities can be bubbled up into ShuffleVertexManager, this feature can be
disabled.
