+## Important update
+
+### Vectorized Execution Engine [Experimental]
+
+In the past, the SQL execution engine of Apache Doris was designed based on the row-based memory format and the traditional volcano model. There was unnecessary overhead in performing SQL operator and function operations, which led to the limited efficiency of the Apache Doris execution engine, which did not Adapt to the architecture of modern CPUs. The goal of the vectorized execution engine is to replace the current row-based SQL execution engine of Apache Doris, fully release the comp [...]
+
+Based on the characteristics of modern CPUs and the execution characteristics of the volcano model, the vectorized execution engine redesigned the SQL execution engine in the columnar storage system:
+
+- Reorganized the data structure of memory, replaced Tuple with Column, improved Cache affinity, branch prediction and prefetch memory friendliness during calculation
+- Type judgment is performed in batches. In this batch, the type determined during type judgment is used, and the virtual function cost of type judgment of each line is allocated to the batch level.
+- Through batch-level type judgment, virtual function calls are eliminated, allowing the compiler to have the opportunity for function inlining and SIMD optimization
+
+This greatly improves the efficiency of the CPU when executing SQL and improves the performance of SQL queries.
+
+In Apache Doris version 1.0, enabling the vectorized execution engine with set batch_size = 4096 and set enable_vectorized_engine = true can significantly improve query performance in most cases. Under the SSB and OnTime standard test datasets, the overall performance of the two scenarios of multi-table association and wide-column query is improved by 3 times and 2.6 times respectively.
+
+
+
+
+
+### Lateral View Grammar [Experimental]
+
+Through Lateral View syntax, we can use Table Function table functions such as explode_bitmap, explode_split, explode_jaon_array, etc., to expand bitmap, String or Json Array from one column into multiple rows, so that the expanded data can be further processed (such as Filter, Join, etc.) .
+
+### Hive External Table [Experimental]
+
+Hive External Table provides users with the ability to directly access Hive tables through Doris. External tables save the tedious data import work, and can use Doris's own OLAP capabilities to solve data analysis problems of Hive tables. The current version supports connecting Hive data sources to Doris, and supports federated queries through data in Doris and Hive data sources for more complex analysis operations.
+
+### Support Z-Order data sorting format
+
+Apache Doris data is sorted and stored according to the prefix column, so when the prefix query condition is included, fast data search can be performed on the sorted data, but if the query condition is not a prefix column, the data sorting feature cannot be used for fast data search. The above problems can be solved by Z-Order Indexing. In version 1.0, we have added the Z-Order data sorting format, which can play a good filtering effect in the scenario of kanban multi-column query and a [...]
+
+### Support for Apache SeaTunnel (Incubating) plugin
+
+Apache SeaTunnel is a high-performance distributed data integration framework built on Apache Spark and Apache Flink. In the 1.0 version of Apache Doris, we have added the SaeTunnel plugin, users can use Apache SeaTunnel for synchronization and ETL between multiple data sources.
+
+### New Function
+
+More bitmap functions are supported, see the function manual for details:
+
+- bitmap_max
+- bitmap_and_not
+- bitmap_and_not_count
+- bitmap_has_all
+- bitmap_and_count
+- bitmap_or_count
+- bitmap_xor_count
+- bitmap_subset_limit
+- sub_bitmap
+
+Support national secret algorithm SM3/SM4;
+
+
+
+> **Note**: The functions marked [Experimental] above are experimental functions. We will continue to optimize and iterate on the above functions in subsequent versions, and further improve them in subsequent versions. If you have any questions or comments during use, please feel free to contact us
+
+### Important Optimization
+
+### Features Optimization
+
+* Reduced the number of segment files generated when importing in large batches to reduce Compaction pressure.
+* Transfer data through BRPC's attachment function to reduce serialization and deserialization overhead during query.
+* Support to directly return binary data of HLL/BITMAP type for external analysis of business.
+* Optimize and reduce the probability of OVERCROWDED and NOT_CONNECTED errors in BRPC, and enhance system stability.
+* Enhance the fault tolerance of import.
+* Support to update and delete data synchronously through Flink CDC.
+* Support adaptive Runtime Filter.
+* Significantly reduce the memory footprint of insert into operations
+
+
+### Usability Improvements
+
+* Routine Load supports displaying the current offset delay number and other status.
+* Added statistics on peak memory usage of queries in FE audit log.
+* Added missing version information to Compaction URL results to facilitate troubleshooting.
+* Support marking BE as non-queryable or non-importable to quickly screen problem nodes.
+
+### Important Bug Fixes
+
+* Fixed several query errors.
+* Fixed some scheduling logic issues in Broker Load.
+* Fix the problem that the metadata cannot be loaded due to the STREAM keyword.
+* Fixed Decommission not executing correctly.
+* Fix the problem that -102 error may occur when operating Schema Change operation in some cases.
+* Fix the problem that using String type may cause BE to crash in some cases.
+
+### Other
+
+* Added Minidump function; easy to locate when problems occur

+## 重要更新
+
+### 向量化执行引擎 [Experimental]
+
+过去 Apache Doris 的 SQL 执行引擎是基于行式内存格式以及基于传统的火山模型进行设计的，在进行 SQL 算子与函数运算时存在非必要的开销，导致 Apache Doris 执行引擎的效率受限，并不适应现代 CPU 的体系结构。向量化执行引擎的目标是替换 Apache Doris 当前的行式 SQL 执行引擎，充分释放现代 CPU 的计算能力，突破在 SQL 执行引擎上的性能限制，发挥出极致的性能表现。
+
+基于现代 CPU 的特点与火山模型的执行特点，向量化执行引擎重新设计了在列式存储系统的 SQL 执行引擎：
+
+- 重新组织内存的数据结构，用 Column替换 Tuple，提高了计算时 Cache 亲和度，分支预测与预取内存的友好度
+- 分批进行类型判断，在本次批次中都使用类型判断时确定的类型，将每一行类型判断的虚函数开销分摊到批量级别。
+- 通过批级别的类型判断，消除了虚函数的调用，让编译器有函数内联以及 SIMD 优化的机会
+
+从而大大提高了 CPU 在 SQL 执行时的效率，提升了 SQL 查询的性能。
+
+在 Apache Doris 1.0 版本中，通过 set batch_size = 4096 和 set enable_vectorized_engine = true 开启向量化执行引擎，多数情况下可显著提升查询性能。在 SSB 和 OnTime 标准测试数据集下，多表关联和宽列查询两大场景的整体性能分别有 3 倍和 2.6 倍的提升。
+
+
+
+
+
+### Lateral View 语法 [Experimental]
+
+通过 Lateral View 语法，我们可以使用 explod_bitmap 、explode_split、explode_jaon_array 等 Table Function 表函数，将 bitmap、String 或 Json Array 由一列展开成多行，以便后续可以对展开的数据进行进一步处理（如 Filter、Join 等）。
+
+### Hive 外表 [Experimental]
+
+Hive External Table 为用户提供了通过 Doris 直接访问 Hive 表的能力，外部表省去了 繁琐的数据导入工作，可以借助 Doris 本身 OLAP 的能力来解决 Hive 表的数据分析问题。当前版本支持将 Hive 数据源接入 Doris，并支持通过 Doris 与 Hive 数据源中的数据进行联邦查询，进行更加复杂的分析操作。
+
+### 支持 Z-Order 数据排序格式
+
+Apache Doris 数据是按照前缀列排序存储的，因此在包含前缀查询条件时，可以在排序数据上进行快速的数据查找，但如果查询条件不是前缀列，则无法利用数据排序的特征进行快速数据查找。通过 Z-Order Indexing 可以解决上述问题，在 1.0 版本中我们增加了 Z-Order 数据排序格式，在看板类多列查询的场景中可以起到很好过滤效果，加速对非前缀列条件的过滤性能。
+
+### 支持 Apache SeaTunnel（Incubating）插件
+
+Apache SeaTunnel 是一个高性能的分布式数据集成框架，架构于 Apache Spark 和 Apache Flink 之上。在 Apache Doris 1.0 版本中，我们增加了 SaeTunnel 插件，用户可以借助 Apache SeaTunnel 进行多数据源之间的同步和 ETL。
+
+### 新增函数
+
+支持更多 bitmap 函数，具体可查看函数手册：
+
+- bitmap_max
+- bitmap_and_not
+- bitmap_and_not_count
+- bitmap_has_all
+- bitmap_and_count
+- bitmap_or_count
+- bitmap_xor_count
+- bitmap_subset_limit
+- sub_bitmap
+
+支持国密算法 SM3/SM4；
+
+
+
+> **注意**：以上标记 [Experimental] 的功能为实验性功能，我们将会在后续版本中对以上功能进行持续优化和迭代，并后续版本中进一步完善。在使用过程中有任何问题或意见，欢迎随时与我们联系
+
+### 重要优化
+
+### 功能优化
+
+* 降低大批量导入时，生成的 Segment 文件数量，以降低 Compaction 压力。
+* 通过 BRPC 的 attachment 功能传输数据，以查询过程中的降低序列化和反序列化开销。
+* 支持直接返回 HLL/BITMAP 类型的二进制数据，用于业务在外侧解析。
+* 优化并降低 BRPC 出现 OVERCROWDED 和 NOT_CONNECTED 错误的概率，增强系统稳定性。
+* 增强导入的容错性。
+* 支持通过 Flink CDC 同步更新和删除数据。
+* 支持自适应的 Runtime Filter。
+* 显著降低 insert into 操作的内存占用
+
+
+### 易用性改进
+
+* Routine Load 支持显示当前 offset 延迟数量等状态。
+* FE audit log 中增加查询峰值内存使用量的统计。
+* Compaction URL 结果中增加缺失版本的信息，方便排查问题。
+* 支持将 BE 标记为不可查询或不可导入，以快速屏蔽问题节点。
+
+### 重要 Bug 修复
+
+* 修复若干查询错误问题。
+* 修复 Broker Load 若干调度逻辑问题。
+* 修复 STREAM 关键词导致元数据无法加载的问题。
+* 修复 Decommission 无法正确执行的问题。
+* 修复部分情况下操作 Schema Change 操作可能出现 -102 错误的问题。
+* 修复部分情况下使用 String 类型可能导致 BE 宕机的问题。
+
+### 其他
+
+* 增加 Minidump 功能；
