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.
