+
+Dear community members, the Apache Doris 3.0.1 version was officially released 
on August 23, 2024, featuring updates and improvements in compute-storage 
decoupling, lakehouse, semi-structured data analysis, asynchronous materialized 
views, and more.
+
+**Quick Download:** https://doris.apache.org/download/
+
+**GitHub Release:** https://github.com/apache/doris/releases
+
+## Behavior Changes
+
+### Query Optimizer
+
+- Added the variable `use_max_length_of_varchar_in_ctas` to control the length 
behavior of VARCHAR type when executing `CREATE TABLE AS SELECT` (CTAS) 
operations.  [#37069](https://github.com/apache/doris/pull/37069)
+  
+  - This variable is set to true by default. 
+  
+  - When set to true, if the VARCHAR type column originates from a table, the 
derived length is used; otherwise, the maximum length is used. 
+  
+  - When set to false, the VARCHAR type will always use the derived length.
+
+- All data types will now be displayed in lowercase to maintain compatibility 
with MySQL format. [#38012](https://github.com/apache/doris/pull/38012)
+
+- Multiple query statements in the same query request must now be separated by 
semicolons. [#38670](https://github.com/apache/doris/pull/38670)
+
+### Query Execution
+
+- The default number of parallel tasks after shuffle operations in the cluster 
is set to 100, which will improve query stability and concurrent processing 
capability in large clusters. 
[#38196](https://github.com/apache/doris/pull/38196)
+
+### Storage
+
+- The default value of `trash_file_expire_time_sec` has been changed from 
86400 seconds to 0 seconds, which means that if files are deleted by mistake 
and the FE trash is cleared, the data cannot be recovered.
+
+- The table attribute `enable_mow_delete_on_delete_predicate` (introduced in 
version 3.0.0) has been renamed to `enable_mow_light_delete`.
+
+- Explicit transactions are now prohibited from performing delete operations 
on tables with written data.
+
+- Heavy schema change operations are prohibited on tables with auto-increment 
fields.
+
+
+
+## New Features
+
+### Job Scheduling
+
+- Optimized the execution logic of internal scheduling jobs, decoupling the 
strong association between start time and immediate execution parameters. Now, 
tasks can be created with a specified start time or selected for immediate 
execution, without conflict, enhancing scheduling flexibility. 
[#36805](https://github.com/apache/doris/pull/36805)
+
+### Compute-Storage Decoupled
+
+- Supports dynamic modification of the upper limit for file cache usage. 
[#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler now supports object storage rate limiting and server-side rate 
limiting retry functionality. 
[#37663](https://github.com/apache/doris/pull/37663) 
[#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- Added the session variable `serde_dialect` to set the output format for 
complex types. [#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL interception now supports external tables.
+
+  - For more information, refer to the documentation on  [SQL 
Interception](https://doris.apache.org/docs/admin-manual/query-admin/sql-interception).
+
+- Insert overwrite now supports Iceberg tables. 
[#37191](https://github.com/apache/doris/pull/37191)
+
+### Asynchronous Materialized Views
+
+- Supports partition roll-up and build at the hourly level. 
[#37678](https://github.com/apache/doris/pull/37678)
+
+- Supports atomic replacement of asynchronous materialized view definition 
statements. [#36749](https://github.com/apache/doris/pull/36749)
+
+- Transparent rewriting now supports Insert statements. 
[#38115](https://github.com/apache/doris/pull/38115)
+
+- Transparent rewriting now supports the VARIANT type. 
[#37929](https://github.com/apache/doris/pull/37929)
+
+### Query Execution
+
+- The group concat function now supports DISTINCT and ORDER BY options. 
[#38744](https://github.com/apache/doris/pull/38744)
+
+### Semi-Structured Data Management
+
+- The ES Catalog now maps `nested` or `object` types in Elasticsearch to the 
JSON type in Doris. [#37101](https://github.com/apache/doris/pull/37101)
+
+- Added the `MULTI_MATCH` function, which supports matching keywords across 
multiple fields and can leverage inverted indexes to accelerate searches. 
[#37722](https://github.com/apache/doris/pull/37722)
+
+- Added the `explode_json_object` function, which can unfold objects in JSON 
data into multiple rows. [#36887](https://github.com/apache/doris/pull/36887)
+
+- Inverted indexes now support memtable advancement, requiring index 
construction only once during multi-replica writes, reducing CPU consumption 
and improving performance. [#35891](https://github.com/apache/doris/pull/35891)
+
+- Added `MATCH_PHRASE` support for positive slop, e.g., `msg MATCH_PHRASE 'a b 
2+'` can match instances containing words a and b with a slop of no more than 
two, and a preceding b; regular slop without the final `+` does not guarantee 
this order. [#36356](https://github.com/apache/doris/pull/36356)
+
+### Other
+
+- Added the FE parameter `skip_audit_user_list`, where user operations 
specified in this configuration will not be recorded in the audit log. 
[#38310](https://github.com/apache/doris/pull/38310)
+
+  - For more information, refer to the documentation on [Audit 
Plugin](https://doris.apache.org/docs/admin-manual/audit-plugin/).
+
+

+## 行为变更
+
+### 查询优化器
+
+- 新增变量 `use_max_length_of_varchar_in_ctas`，用于控制在执行 `CREATE TABLE AS 
SELECT`（CTAS）操作时 VARCHAR 类型的长度行为。此变量默认设置为 true。当设置为 true 时，如果 VARCHAR 
类型的列源自一个表，则采用推导长度；否则，使用最大长度。当设置为 false 时，VARCHAR 
类型将始终使用推导出的长度。[#37069](https://github.com/apache/doris/pull/37069)
+
+- 所有的数据类型将以小写形式展示，以保持与 MySQL 
格式的兼容性。[#38012](https://github.com/apache/doris/pull/38012)
+
+- 同一查询请求中的多条查询语句现在必须使用分号分隔。[#38670](https://github.com/apache/doris/pull/38670)
+
+### 查询执行
+
+- 将集群在执行 Shuffle 操作后默认的并行任务数设置为 
100，这将提高大型集群中查询的稳定性和并发处理能力。[#38196](https://github.com/apache/doris/pull/38196)
+
+### 存储
+
+- `trash_file_expire_time_sec` 的默认值已从 86400 秒更改为 0 秒，这意味着如果误删除文件并清空了 FE 
回收站，数据将无法恢复。
+
+- 表属性 `enable_mow_delete_on_delete_predicate`（在版本 3.0.0 中引入）已更名为 
`enable_mow_light_delete`。
+
+- 显式事务现在被禁止对已写入数据的表执行 Delete 操作。
+
+- 禁止对含有自增字段的表进行重量级的 Schema Change 操作。
+
+## 新特性
+
+### 任务调度
+
+- 
优化内部调度作业的执行逻辑，取消开始时间和立即执行参数之间的强关联。现在任务在创建时可以指定开始时间或选择立即执行，两者不再冲突，从而提高了调度的灵活性。[#36805](https://github.com/apache/doris/pull/36805)
+
+### 存算分离
+
+- 支持动态更改 File Cache 的使用上限。[#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler 
现在支持对象存储限速以及服务端限速重试功能。[#37663](https://github.com/apache/doris/pull/37663) 
[#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- 新增会话变量 
`serde_dialect`，可以设置复杂类型的输出格式。[#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL 拦截功能现在支持外部表
+
+  - 更多内容，参考文档[SQL 
拦截](https://doris.apache.org/zh-CN/docs/admin-manual/query-admin/sql-interception)
+
+- Insert Overwrite 现在支持 Iceberg 
表。[#37191](https://github.com/apache/doris/pull/37191)
+
+### 异步物化视图
+
+- 支持按小时级别分区上卷构建。[#37678](https://github.com/apache/doris/pull/37678)
+
+- 支持原子替换异步物化视图定义语句。[#36749](https://github.com/apache/doris/pull/36749)
+
+- 透明改写现在支持 Insert 语句。[#38115](https://github.com/apache/doris/pull/38115)
+
+- 透明改写现在支持 Variant 类型。[#37929](https://github.com/apache/doris/pull/37929)
+
+### 查询执行
+
+- Group Concat 函数现在支持 DISTINCT 和 ORDER BY 
选项。[#38744](https://github.com/apache/doris/pull/38744)
+
+### 半结构化数据管理
+
+- ES Catalog 现在将 Elasticsearch 中的 `nested` 或 `object` 类型映射为 Doris 的 JSON 
类型。[#37101](https://github.com/apache/doris/pull/37101)
+
+- 新增 `MULTI_MATCH` 
函数，支持在多个字段中匹配关键词，并能利用倒排索引加速搜索。[#37722](https://github.com/apache/doris/pull/37722)
+
+- 新增 `explode_json_object` 函数，可以将 JSON 数据中的 Object 
展开为多行。[#36887](https://github.com/apache/doris/pull/36887)
+
+- 倒排索引现在支持 Memtable 前移，在多副本写入时只需构建一次索引，减少 CPU 
消耗并提升性能。[#35891](https://github.com/apache/doris/pull/35891)
+
+- 新增 `MATCH_PHRASE` 支持正向词距（slop），例如 `msg MATCH_PHRASE 'a b 2+'` 可以匹配包含词 a 和 
b，它们之间的词距不超过两个，并且 a 在 b 的前面；而普通的词距（slop）如果没有最后的加号 `+`，则不保证 a 在 b 
的前面。[#36356](https://github.com/apache/doris/pull/36356)
+
+### 其他
+
+- 新增加了 FE 参数 
`skip_audit_user_list`，在此配置项中的用户操作将不会被记录到审计日志中。[#38310](https://github.com/apache/doris/pull/38310)
+  
+  -

+
+## Behavior Changes
+
+### Query Optimizer
+
+- Added the variable `use_max_length_of_varchar_in_ctas` to control the length 
behavior of VARCHAR type when executing `CREATE TABLE AS SELECT` (CTAS) 
operations.  [#37069](https://github.com/apache/doris/pull/37069)
+  
+  - This variable is set to true by default. 
+  
+  - When set to true, if the VARCHAR type column originates from a table, the 
derived length is used; otherwise, the maximum length is used. 
+  
+  - When set to false, the VARCHAR type will always use the derived length.
+
+- All data types will now be displayed in lowercase to maintain compatibility 
with MySQL format. [#38012](https://github.com/apache/doris/pull/38012)
+
+- Multiple query statements in the same query request must now be separated by 
semicolons. [#38670](https://github.com/apache/doris/pull/38670)
+
+### Query Execution
+
+- The default number of parallel tasks after shuffle operations in the cluster 
is set to 100, which will improve query stability and concurrent processing 
capability in large clusters. 
[#38196](https://github.com/apache/doris/pull/38196)
+
+### Storage
+
+- The default value of `trash_file_expire_time_sec` has been changed from 
86400 seconds to 0 seconds, which means that if files are deleted by mistake 
and the FE trash is cleared, the data cannot be recovered.
+
+- The table attribute `enable_mow_delete_on_delete_predicate` (introduced in 
version 3.0.0) has been renamed to `enable_mow_light_delete`.
+
+- Explicit transactions are now prohibited from performing delete operations 
on tables with written data.
+
+- Heavy schema change operations are prohibited on tables with auto-increment 
fields.
+
+
+
+## New Features
+
+### Job Scheduling
+
+- Optimized the execution logic of internal scheduling jobs, decoupling the 
strong association between start time and immediate execution parameters. Now, 
tasks can be created with a specified start time or selected for immediate 
execution, without conflict, enhancing scheduling flexibility. 
[#36805](https://github.com/apache/doris/pull/36805)
+
+### Compute-Storage Decoupled
+
+- Supports dynamic modification of the upper limit for file cache usage. 
[#37484](https://github.com/apache/doris/pull/37484)
+
+- Recycler now supports object storage rate limiting and server-side rate 
limiting retry functionality. 
[#37663](https://github.com/apache/doris/pull/37663) 
[#37680](https://github.com/apache/doris/pull/37680)
+
+### Lakehouse
+
+- Added the session variable `serde_dialect` to set the output format for 
complex types. [#37039](https://github.com/apache/doris/pull/37039)
+
+- SQL interception now supports external tables.
+
+  - For more information, refer to the documentation on  [SQL 
Interception](https://doris.apache.org/docs/admin-manual/query-admin/sql-interception).
+
+- Insert overwrite now supports Iceberg tables. 
[#37191](https://github.com/apache/doris/pull/37191)
+
+### Asynchronous Materialized Views
+
+- Supports partition roll-up and build at the hourly level. 
[#37678](https://github.com/apache/doris/pull/37678)
+
+- Supports atomic replacement of asynchronous materialized view definition 
statements. [#36749](https://github.com/apache/doris/pull/36749)
+
+- Transparent rewriting now supports Insert statements. 
[#38115](https://github.com/apache/doris/pull/38115)
+
+- Transparent rewriting now supports the VARIANT type. 
[#37929](https://github.com/apache/doris/pull/37929)
+
+### Query Execution
+
+- The group concat function now supports DISTINCT and ORDER BY options. 
[#38744](https://github.com/apache/doris/pull/38744)
+
+### Semi-Structured Data Management
+
+- The ES Catalog now maps `nested` or `object` types in Elasticsearch to the 
JSON type in Doris. [#37101](https://github.com/apache/doris/pull/37101)
+
+- Added the `MULTI_MATCH` function, which supports matching keywords across 
multiple fields and can leverage inverted indexes to accelerate searches. 
[#37722](https://github.com/apache/doris/pull/37722)
+
+- Added the `explode_json_object` function, which can unfold objects in JSON 
data into multiple rows. [#36887](https://github.com/apache/doris/pull/36887)
+
+- Inverted indexes now support memtable advancement, requiring index 
construction only once during multi-replica writes, reducing CPU consumption 
and improving performance. [#35891](https://github.com/apache/doris/pull/35891)
+
+- Added `MATCH_PHRASE` support for positive slop, e.g., `msg MATCH_PHRASE 'a b 
2+'` can match instances containing words a and b with a slop of no more than 
two, and a preceding b; regular slop without the final `+` does not guarantee 
this order. [#36356](https://github.com/apache/doris/pull/36356)
+
+### Other
+
+- Added the FE parameter `skip_audit_user_list`, where user operations 
specified in this configuration will not be recorded in the audit log. 
[#38310](https://github.com/apache/doris/pull/38310)
+
+  - For more information, refer to the documentation on [Audit 
Plugin](https://doris.apache.org/docs/admin-manual/audit-plugin/).
