+Currently, partition compensation is supported, but compensation with conditional UNION ALLis not yet available.
+
+For example, if a materialized view contains a WHEREclause—such as adding the filter WHERE l_shipdate > '2023-10-19'in the example above—while
+the query condition is WHERE l_shipdate > '2023-10-18', this scenario currently cannot be compensated via UNION ALL. Support for this case is planned for a future release.
+:::
+
+:::info Note
+Starting from version 3.1.0
+The partition compensation rewrite feature supports the following types of partitioned tables: internal tables, Hive, Iceberg, and Paimon.
+
+This means that the partition compensation mechanism can only be triggered when a partitioned materialized view is built on partitioned tables of the aforementioned types.

 ### Nested Materialized View Rewriting
 
 The SQL definition of a materialized view can use another materialized view; this is called a nested materialized view.

 比如，如果物化视图带有 `where` 条件，以上述为例，如果构建物化的过滤条件加上 ` WHERE l_shipdate > '2023-10-19'`，而查询是 `WHERE l_shipdate > '2023-10-18'`，目前这种还无法通过 `UNION ALL` 补偿，待支持。

+从 3.1.0 版本开始
+分区补偿改写功能支持以下类型的分区表：内表、Hive、Iceberg 与 Paimon。这意味着，仅当分区物化视图是基于上述类型的分区表构建时，才能触发分区补偿改写机制。

 ### 嵌套物化视图改写
 
 物化视图的定义 SQL 可以使用物化视图，此物化视图称为嵌套物化视图。
