## *Tips* - *Thank you very much for contributing to Apache Hudi.* - *Please review https://hudi.apache.org/contribute/how-to-contribute before opening a pull request.* ## What is the purpose of the pull request Currently, all Hudi `Relation`s bear performance gap relative to Spark's `HadoopFsRelation` and the reason to that is `SchemaPruning` optimization rule (pruning nested schemas) that is unfortunately predicated on usage of `HadoopFsRelation`, meaning that it's not applied in cases when any other relation is used. This change is porting this rule to Hudi relations (MOR, Incremental, etc) by the virtue of leveraging `HoodieSparkSessionExtensions` mechanism injecting modified version of the original `SchemaPruning` rule that is adopted to work w/ Hudi's custom relations. ## Brief change log - Added customOptimizerRules to HoodieAnalysis - Added NestedSchemaPrunning Spark's Optimizer rule - Handle Spark's Optimizer pruned data schema (to effectively prune nested schemas) - Enable HoodieClientTestHarness to inject `HoodieSparkSessionExtensions` - Injecting Spark Session extensions for `TestMORDataSource`, `TestCOWDataSource` - Disabled fallback to `HadoopFsRelation` ## Verify this pull request This pull request is already covered by existing tests, such as *(please describe tests)*.
