> When HoodieIncrSource is used to fetch the update from another Hudi table, 
> the IncrementalRelation will be used to read the data. But it has a 
> performance issue because the column pruning and predicate pushdown don't 
> happen. As the result, Hudi reads too much useless data.
> By enabling the column pruning and predicate pushdown, the data to read is 
> reduced dramatically.
