+# Query Cache（查询缓存）
+
+## 概述
+
+在分析型查询场景中，同一个聚合查询经常会被重复执行，而底层数据并未发生变化。例如：
+
+```sql
+SELECT region, SUM(revenue) FROM orders WHERE dt = '2024-01-01' GROUP BY
region;
+SELECT region, SUM(revenue) FROM orders WHERE dt = '2024-01-01' GROUP BY
region;
Review Comment:
我建议
1. 这里给的例子是分区有重叠，但不完全相同的sql，表示可以共用这部分的交集的缓存。
然后再下面讲清楚缓存的是交集的部分
2. 明确讲清楚缓存的不是整个sql的结果，而是聚合算子的中间结果
