>
> 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.
