> encounters ArrayOutOfBound exception.
> The boundary conditions are:
>  * The complete batch of the big table should have the join key repeated for 
> all the join columns.

> value in the small table
>  * The repeated value should not be a null value
>  * Some rows should be filtered out as part of the on clause filter.
