+
+ Storage Page Cache and Chunk Allocator cache user data blocks and memory preallocation, respectively.
+
+ These two functions take up a certain percentage of memory and will not be released. This part of memory cannot be flexibly allocated, which leads to insufficient memory for other tasks due to this part of memory occupation in some scenarios, affecting system stability and availability. Therefore, we disabled these two features by default in version 1.1.3.
+
+ However, in some latency-sensitive reporting scenarios, turning off this feature may lead to increased query latency. If you are worried about the impact of this feature on your business after upgrade, you can add the following parameters to be.conf to keep the same behavior as the previous version.
+
+ ```
+ disable_storage_page_cache=false
+ chunk_reserved_bytes_limit=10%
+ ```
+
+ * ``disable_storage_page_cache``: Whether to disable Storage Page Cache. version 1.1.2 (inclusive), the default is false, i.e., on. version 1.1.3 defaults to true, i.e., off.
+ * `chunk_reserved_bytes_limit`: Chunk allocator reserved memory size. 1.1.2 (and earlier), the default is 10% of the overall memory. 1.1.3 version default is 209715200 (200MB).

## Test the correctness of BE upgrade
1. Arbitrarily select a BE node and deploy the latest doris_be binary file.

+ Storage Page Cache 和 Chunk Allocator 分别缓存用户数据块和内存预分配。
+
+ 这两个功能会占用一定比例的内存，并且不会释放。 这部分内存占用无法灵活调配，导致在某些场景下，因这部分内存占用而导致其他任务内存不足，影响系统稳定性和可用性。因此我们在 1.1.3 版本中默认关闭了这两个功能。

+ 但在某些延迟敏感的报表场景下，关闭该功能可能会导致查询延迟增加。如用户担心升级后该功能对业务造成影响，可以通过在 be.conf 中增加以下参数以保持和之前版本行为一致。

## 测试 BE 升级正确性
1. 任意选择一个 BE 节点，部署最新的 doris_be 二进制文件。
