----------------------------

             Summary: Performance improvement for IncrementalRelation
                 Key: HUDI-2754
                 URL: https://issues.apache.org/jira/browse/HUDI-2754
             Project: Apache Hudi
          Issue Type: Bug
          Components: Incremental Pull
            Reporter: Jintao


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.
