Deegue created SPARK-26667:
------------------------------

             Summary: Add `Scanning Input Table` to Performance Tuning Guide
                 Key: SPARK-26667
                 URL: https://issues.apache.org/jira/browse/SPARK-26667
             Project: Spark
          Issue Type: Documentation
          Components: Documentation
    Affects Versions: 2.4.1, 3.0.0
            Reporter: Deegue


We can use `CombineTextInputFormat` instead of `TextInputFormat` and set configurations to increase the speed while reading a table. 

There's no need to add spark configurations,  [link title|[https://github.com/apache/spark/pull/23506],] so add it to the Performance Tuning.
