+Apache Doris version 2.1.4 was officially released on June 26, 2024. In this
update, we have optimized various functional experiences for data lakehouse
scenarios, with a focus on resolving the abnormal memory usage issue in the
previous version. Additionally, we have implemented several improvemnents and
bug fixes to enhance the stability. Welcome to download and use it.

+**GitHub Release:** https://github.com/apache/doris/releases
+
+
+## Behavior Changed
+
+- Non-existent files will be ignored when querying external tables such as
Hive. [#35319](https://github.com/apache/doris/pull/35319)
+
+ The file list is obtained from the meta cache, and it may not be consistent
with the actual file list.
+
+ Ignoring non-existent files helps to avoid query errors.
+
+- By default, creating a Bitmap Index will no longer be automatically changed
to an Inverted Index. [#35521](https://github.com/apache/doris/pull/35521)
+
+ This behavior is controlled by the FE configuration item
`enable_create_bitmap_index_as_inverted_index`, which defaults to false.
+
+- When starting FE and BE processes using `--console`, all logs will be output
to the standard output and differentiated by prefixes indicating the log type.
[#35679](https://github.com/apache/doris/pull/35679)
+
+ For more infomation, please see the documentations:
+
+ - [Log Management - FE
Log](https://doris.apache.org/docs/admin-manual/log-management/fe-log)
+
+ - [Log Management - FE
Log](https://doris.apache.org/docs/admin-manual/log-management/be-log)
+
+- If no table comment is provided when creating a table, the default comment
will be empty instead of using the table type as the default comment.
[#36025](https://github.com/apache/doris/pull/36025)
+
+- The default precision of DECIMALV3 has been adjusted from (9, 0) to (38, 9)
to maintain compatibility with the version in which this feature was initially
released. [#36316](https://github.com/apache/doris/pull/36316)
+

+**Apache Doris 2.1.4 版本已于 2024 年 6 月 26 日正式发布。**在 2.1.4
版本中，我们对数据湖分析场景进行了多项功能体验优化，重点修复了旧版本中异常内存占用的问题，同时提交了若干改进项以及问题修复，进一步提升了系统的性能、稳定性及易用性，欢迎大家下载使用。
+
+**官网下载：** https://doris.apache.org/download/
+
+**GitHub 下载：** https://github.com/apache/doris/releases
+
+## 行为变更
+
+- **通过 Catalog 查询外部表（如 Hive 数据表）时，系统将忽略不存在的文件：**
当从元数据缓存中获取文件列表时，由于缓存更新并非实时，因此可能存在实际的文件列表已删除、而元数据缓存中仍存在该文件的情况。为了避免由于尝试访问不存在的文件而导致的查询错误，系统会忽略这些不存在的文件。
[#35319](https://github.com/apache/doris/pull/35319)
+
+- 默认情况下，创建 Bitmap Index 不再默认变更为 Inverted Index。该行为由 FE 配置项
`enable_create_bitmap_index_as_inverted_index` 控制，默认为
FALSE。[#35521](https://github.com/apache/doris/pull/35521)
+
+- 当使用 `--console` 启动 FE、BE
进程时，所有日志将输出到标准输出，并通过前缀区分不同类型的日志。[#35679](https://github.com/apache/doris/pull/35679)
+
+ 关于更多信息，请参考文档：
+
+ - [BE
日志管理](https://doris.apache.org/zh-CN/docs/admin-manual/log-management/be-log)
+
+ - - [FE
日志管理](https://doris.apache.org/zh-CN/docs/admin-manual/log-management/fe-log)
+
+- 如果建表时没有填写表注释，默认注释为空，不再使用表类型作为默认表注释。
[#36025](https://github.com/apache/doris/pull/36025)
+
+- DECIMALV3 的默认精度从 (9, 0) 调整为 (38,9) ，以和最初发布此功能的版本保持兼容。
[#36316](https://github.com/apache/doris/pull/36316)
+
+## 新功能
+
+### 01 查询优化器
+
+- **支持 FE 火焰图工具**：在 FE 部署目录 `${DORIS_FE_HOME}/bin` 中会增加`profile_fe.sh` 脚本，可以利用
async-profiler 工具生成 FE 的火焰图，用以发现性能瓶颈点。
+
+ 关于更多信息，请参考文档：[使用 FE Profiler
生成火焰图](https://doris.apache.org/zh-CN/community/developer-guide/fe-profiler)
+
+- **支持 SELECT DISTINCT 与聚合函数同时使用**：支持 `SELECT DISTINCT`
与聚合函数同时使用，在一个查询中同时去重和进行聚合操作，如 SUM、MIN/MAX 等。
+
+- **支持无 GROUP BY 的单表查询重写**：无 `GROUP BY`
的单表查询重写功能允许数据库优化器在不需要分组的情况下，根据查询的复杂性和数据表的结构，自动选择最佳的执行计划来执行查询，这可以提高查询的性能，减少不必要的资源消耗，并简化查询逻辑。
[#35242](https://github.com/apache/doris/pull/35242).
+
+- **查询优化器全面支持高并发点查询功能**：在 2.1.4 版本之后，查询优化器全面支持高并发点查询功能，所有符合点查询条件的 SQL
语句会自动走短路径查询，无需用户在客户端额外设置 `set experimental_enable_nereids_planner = false`。
[#36205](https://github.com/apache/doris/pull/36205).
+
+### 02 湖仓一体
+
+- **支持 Paimon 的原生读取器来处理 Deletion Vector：** Deletion Vector
主要用于标记或追踪哪些数据已被删除或标记为删除，通常应用在需要保留历史数据的场景，基于本优化可以提升大量数据更新或删除时的处理效率。
[#35241](https://github.com/apache/doris/pull/35241)
+
+ 关于更多信息，请参考文档：[数据湖分析 -
Paimon](https://doris.apache.org/zh-CN/docs/lakehouse/datalake-analytics/paimon)
+
+- **支持在表值函数（TVF）中使用 Resource**：TVF 功能为 Apache Doris 提供了直接将对象存储或 HDFS 上的文件作为
Table 进行查询分析的能力。通过在 TVF 中引用 Resource，可以避免重复填写连接信息，提升使用体验。
[#35139](https://github.com/apache/doris/pull/35139)
+
+ 关于更多信息，请参考文档：[表函数 -
HDFS](https://doris.apache.org/zh-CN/docs/sql-manual/sql-functions/table-functions/hdfs/)
+
+- **支持通过 Ranger 插件实现数据脱敏**：开启 Ranger 鉴权功能后，支持使用 Ranger 中的 Data Mask 功能进行数据脱敏。
+
+ 关于更多信息，请参考文档：[基于 Apache Ranger
的鉴权管理](https://doris.apache.org/zh-CN/docs/admin-manual/auth/ranger/#data-mask-%E7%A4%BA%E4%BE%8B)

+**Apache Doris 2.1.4 版本已于 2024 年 6 月 26 日正式发布。**在 2.1.4
版本中，我们对数据湖分析场景进行了多项功能体验优化，重点修复了旧版本中异常内存占用的问题，同时提交了若干改进项以及问题修复，进一步提升了系统的性能、稳定性及易用性，欢迎大家下载使用。
+
+**官网下载：** https://doris.apache.org/download/
+
+**GitHub 下载：** https://github.com/apache/doris/releases
+
+## 行为变更
+
+- **通过 Catalog 查询外部表（如 Hive 数据表）时，系统将忽略不存在的文件：**
当从元数据缓存中获取文件列表时，由于缓存更新并非实时，因此可能存在实际的文件列表已删除、而元数据缓存中仍存在该文件的情况。为了避免由于尝试访问不存在的文件而导致的查询错误，系统会忽略这些不存在的文件。
[#35319](https://github.com/apache/doris/pull/35319)
+
+- 默认情况下，创建 Bitmap Index 不再默认变更为 Inverted Index。该行为由 FE 配置项
`enable_create_bitmap_index_as_inverted_index` 控制，默认为
FALSE。[#35521](https://github.com/apache/doris/pull/35521)
+
+- 当使用 `--console` 启动 FE、BE
进程时，所有日志将输出到标准输出，并通过前缀区分不同类型的日志。[#35679](https://github.com/apache/doris/pull/35679)
+
+ 关于更多信息，请参考文档：
+
+ - [BE
日志管理](https://doris.apache.org/zh-CN/docs/admin-manual/log-management/be-log)
+
+ - - [FE
日志管理](https://doris.apache.org/zh-CN/docs/admin-manual/log-management/fe-log)
+
+- 如果建表时没有填写表注释，默认注释为空，不再使用表类型作为默认表注释。
[#36025](https://github.com/apache/doris/pull/36025)
+
+- DECIMALV3 的默认精度从 (9, 0) 调整为 (38,9) ，以和最初发布此功能的版本保持兼容。
[#36316](https://github.com/apache/doris/pull/36316)
+
+## 新功能
+
+### 01 查询优化器
+
+- **支持 FE 火焰图工具**：在 FE 部署目录 `${DORIS_FE_HOME}/bin` 中会增加`profile_fe.sh` 脚本，可以利用
async-profiler 工具生成 FE 的火焰图，用以发现性能瓶颈点。
+
+ 关于更多信息，请参考文档：[使用 FE Profiler
生成火焰图](https://doris.apache.org/zh-CN/community/developer-guide/fe-profiler)
+
+- **支持 SELECT DISTINCT 与聚合函数同时使用**：支持 `SELECT DISTINCT`
与聚合函数同时使用，在一个查询中同时去重和进行聚合操作，如 SUM、MIN/MAX 等。
+
+- **支持无 GROUP BY 的单表查询重写**：无 `GROUP BY`
的单表查询重写功能允许数据库优化器在不需要分组的情况下，根据查询的复杂性和数据表的结构，自动选择最佳的执行计划来执行查询，这可以提高查询的性能，减少不必要的资源消耗，并简化查询逻辑。
[#35242](https://github.com/apache/doris/pull/35242).
+
+- **查询优化器全面支持高并发点查询功能**：在 2.1.4 版本之后，查询优化器全面支持高并发点查询功能，所有符合点查询条件的 SQL
语句会自动走短路径查询，无需用户在客户端额外设置 `set experimental_enable_nereids_planner = false`。
[#36205](https://github.com/apache/doris/pull/36205).
+
+### 02 湖仓一体
+
+- **支持 Paimon 的原生读取器来处理 Deletion Vector：** Deletion Vector
主要用于标记或追踪哪些数据已被删除或标记为删除，通常应用在需要保留历史数据的场景，基于本优化可以提升大量数据更新或删除时的处理效率。
[#35241](https://github.com/apache/doris/pull/35241)
+
+ 关于更多信息，请参考文档：[数据湖分析 -
Paimon](https://doris.apache.org/zh-CN/docs/lakehouse/datalake-analytics/paimon)
+
+- **支持在表值函数（TVF）中使用 Resource**：TVF 功能为 Apache Doris 提供了直接将对象存储或 HDFS 上的文件作为
Table 进行查询分析的能力。通过在 TVF 中引用 Resource，可以避免重复填写连接信息，提升使用体验。
[#35139](https://github.com/apache/doris/pull/35139)
+
+ 关于更多信息，请参考文档：[表函数 -
HDFS](https://doris.apache.org/zh-CN/docs/sql-manual/sql-functions/table-functions/hdfs/)
+
+- **支持通过 Ranger 插件实现数据脱敏**：开启 Ranger 鉴权功能后，支持使用 Ranger 中的 Data Mask 功能进行数据脱敏。
+
+ 关于更多信息，请参考文档：[基于 Apache Ranger
的鉴权管理](https://doris.apache.org/zh-CN/docs/admin-manual/auth/ranger/#data-mask-%E7%A4%BA%E4%BE%8B)

+Apache Doris version 2.1.4 was officially released on June 26, 2024. In this
update, we have optimized various functional experiences for data lakehouse
scenarios, with a focus on resolving the abnormal memory usage issue in the
previous version. Additionally, we have implemented several improvemnents and
bug fixes to enhance the stability. Welcome to download and use it.

+
+
+## Behavior Changed
+
+- Non-existent files will be ignored when querying external tables such as
Hive. [#35319](https://github.com/apache/doris/pull/35319)
+
+ The file list is obtained from the meta cache, and it may not be consistent
with the actual file list.
+
+ Ignoring non-existent files helps to avoid query errors.
+
+- By default, creating a Bitmap Index will no longer be automatically changed
to an Inverted Index. [#35521](https://github.com/apache/doris/pull/35521)
+
+ This behavior is controlled by the FE configuration item
`enable_create_bitmap_index_as_inverted_index`, which defaults to false.
+
+- When starting FE and BE processes using `--console`, all logs will be output
to the standard output and differentiated by prefixes indicating the log type.
[#35679](https://github.com/apache/doris/pull/35679)
+
+ For more infomation, please see the documentations:
+
+ - [Log Management - FE
Log](https://doris.apache.org/docs/admin-manual/log-management/fe-log)
+
+ - [Log Management - FE
Log](https://doris.apache.org/docs/admin-manual/log-management/be-log)
+
+- If no table comment is provided when creating a table, the default comment
will be empty instead of using the table type as the default comment.
[#36025](https://github.com/apache/doris/pull/36025)
+
+- The default precision of DECIMALV3 has been adjusted from (9, 0) to (38, 9)
to maintain compatibility with the version in which this feature was initially
released. [#36316](https://github.com/apache/doris/pull/36316)
