&lt;p&gt;&lt;b&gt;새 문서&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== XPLAN에서 View Pushed Predicate 항목 ==&lt;br /&gt;
* `VIEW PUSHED PREDICATE`는 Oracle 옵티마이저가 뷰(View)의 성능을 최적화하기 위해 필터 조건을 뷰 내부로 밀어 넣는(push down) 실행 계획을 나타냅니다. &lt;br /&gt;
* 이 최적화 기법은 뷰의 기본 테이블에서 더 적은 데이터를 읽게 만들어 I/O를 줄이고 쿼리 성능을 크게 향상시킵니다.&lt;br /&gt;
&lt;br /&gt;
=== VIEW PUSHED PREDICATE 원리 ===&lt;br /&gt;
# 일반적인 VIEW Merge 처리 실행 순서&lt;br /&gt;
## 뷰 실행 : 뷰가 정의된 SQL을 실행하여 가상 테이블(virtual table) 생성.&lt;br /&gt;
## 필터 적용 : 그 결과에 쿼리의 `WHERE` 절 조건을 적용하여 최종 결과 반영&lt;br /&gt;
# `VIEW PUSHED PREDICATE` 처리 실행 순서&lt;br /&gt;
## 필터 푸시 다운 : 쿼리의 `WHERE` 절에 있는 조건이 뷰의 SQL 내부로 PUSH 되어 먼저 실행.&lt;br /&gt;
## 뷰 실행: PUSH된 조건에 따라 뷰의 기본 테이블에서 필요한 데이터만 필터링 처리.&lt;br /&gt;
&lt;br /&gt;
==== VIEW PUSH DOWN 효율성 예시 ====&lt;br /&gt;
* 예를 들어, 100만 건의 데이터를 가진 테이블로 만든 뷰가 있고, 사용자는 그중 100건만 필요로 하는 쿼리를 실행한다고 가정&lt;br /&gt;
# 푸시 다운이 없는 경우: 100만 건 전체를 뷰에서 읽어온 후, `WHERE` 절을 적용해 100건을 필터링합니다. 이는 매우 비효율적&lt;br /&gt;
# 푸시 다운이 있는 경우: `WHERE` 절 조건이 뷰 내부로 들어가 100만 건 중 처음부터 100건만 읽게 됩니다. 결과적으로 I/O와 CPU 사용량이 획기적으로 줄어듭니다.&lt;br /&gt;
