+# Apache Doris(Incubating) 0.15.0 Release
+
+Dear Community, After months of polishing, we are pleased to announce the release of Apache Doris(Incubating) on November 29, 2021! Nearly 700 optimizations and fixes have been submitted by 99 contributors to Apache Doris, and we'd like to express our sincere gratitude to all of them!
+
+In the 0.15.0 Release, we have added many new features to optimize Apache Doris's query performance, ease of use, and stability: a new resource division and isolation feature that allows users to divide BE nodes in a cluster into resource groups by means of resource tags, enabling unified management of online and offline services and resource isolation; the addition of Runtime Filter and Join Reorder functions have been added to significantly improve the query efficiency of multi-table J [...]
+
+We welcome you to contact us via GitHub Discussion or the Dev email group if you have any questions during use, and we look forward to your participation in community discussions and building.
+
+## High Lights
+
+### Resource Segregation and Isolation
+
+You can divide BE nodes in a Doris cluster into resource groups by using resource tags, allowing you to manage online and offline operations and isolate resources at the node level.
+You can also control the resource overhead of individual queries by limiting the CPU and memory overhead and complexity of individual query tasks, thus reducing the resource hogging problem between different queries.
+
+### Performance Optimization
+
+* The Runtime Filter feature can significantly improve query efficiency in most Join scenarios by using the Join Key column condition of the right table in the Join algorithm to filter the data in the left table. For example, you can get 2-10 times performance improvement under Star Schema Benchmark (TPCH's streamlined test set).
+
+* The Join Reorder feature can automatically help adjust the order of joins in SQL by using a cost model to help achieve optimal join efficiency.
+It can be enabled via the session variable `set enable_cost_based_join_reorder=true`.
+
+### New features
+
+* Support synchronizing MySQL binlog data directly to Canal Server.
+* Support String column type, support up to 2GB.
+* Support List partitioning, you can create partitions for enumerated values.
+* Support transactional Insert statement function. You can import data in bulk by begin ; insert ; insert;, ... You can import data in bulk by begin ; insert ; insert ;, ... ;.
+* Support Update statement function on Unique Key model. You can execute Update Set where statement on Unique Key model table.
+* Support SQL blocking list function. You can block some SQL execution by regular, hash value matching, etc.
+* Support LDAP login authentication.
+
+### Extended Features
+
+* Support Flink-Doris-Connector.
+* Support for DataX doriswriter plugin.
+* Spark-Doris-Connector support for data writing to Doris.
+
+## Feature Optimization
+
+### Query
+
+* Support for computing all constant expressions in the SQL query planning phase using BE's functional computing power.
+
+### Import
+
+* Support for specifying multi-byte row separators or invisible separators when importing text format files.
+* Supports importing compressed format files via Stream Load.
+* Stream Load supports importing Json data in multi-line format.
+
+### Export
+
+* Support Export export function to specify where filter. Supports exporting files with multi-byte row separators. Support export to local files.
+* Export export function supports exporting only specified columns.
+* Supports exporting the result set to local disk via outfile statement and writing the exported marker file after exporting.
+
+### Ease of use
+
+* Dynamic partitioning function supports creating and keeping specified historical partitions, and supports automatic hot and cold data migration settings.
+* Supports displaying queries, imported schedules and Profiles using a visual tree structure at the command line.
+* Support to record and view Stream Load operation logs.
+* When consuming Kafka data via Routine Load, you can specify the time point for consumption.
+* Supports exporting Routine Load creation statements by show create routine load function.
+* Support to start and stop all Routine Load jobs with one click by pause/resume all routine load command.
+* Supports modifying the Broker List and Topic of Routine Load by alter routine load statement.
+* Support create table as select function.
+* Support modify column comments and table comments by alter table command.
+* show tablet status to add table creation time and data update time.
+* Support show data skew command to check the data volume distribution of a table to troubleshoot data skewing problems.
+* Support show/clean trash command to check the disk occupation of BE file recycle bin and clear it actively.
+* Support show view statement to show which views a table is referenced by.
+
+### New functions
+
+* `bitmap_min`, `bit_length`
+* `yearweek`, `week`, `makedate`
+* `percentile` exact percentile function
+* `json_array`, `json_object`, `json_quote`
+* Support for creating custom public keys for the `AES_ENCRYPT` and `AES_DECRYPT` functions.
+* Support for creating function aliases to combine multiple functions by `create alias function`.
+
+### Other
+
+* Support for accessing the ES exterior of the SSL connection protocol.
+* Support specifying the number of hotspot partitions in the dynamic partition property, which will be stored in SSD disks.
+* Support importing Json format data via Broker Load.
+* Supports accessing HDFS directly through libhdfs3 library for data import and export without the Broker process.
+* select into outfile function supports exporting Parquet file format and parallel export.
+* ODBC external table support for SQLServer.
+

+
+我们欢迎大家在使用过程中，有任何问题通过 GitHub Discussion 或者 Dev 邮件组与我们取得联系，也期待大家参与社区讨论和建设中 。
+
+
+## 重要更新
+
+### 资源划分与隔离

+同时，还可以通过限制单个查询任务的 CPU、内存开销以及复杂度，来控制单个查询的资源开销，从而降低不同查询之间的资源抢占问题。
+
+### 性能优化
+
+* Runtime Filter 功能通过使用 Join 算子中右表的 Join Key 列条件来过滤左表的数据，在大部分 Join 场景下可以显著提升查询效率。如在 Star Schema Benchmark ( TPCH 的精简测试集) 下可以获得 2-10 倍的性能提升。
+
+* Join Reorder 功能可以通过通过代价模型自动帮助调整 SQL 中 Join 的顺序，以帮助获得最优的 Join 效率。
+可通过会话变量 `set enable_cost_based_join_reorder=true` 开启。
+
+### 新增功能
+
+* 支持直接对接 Canal Server 同步 MySQL binlog 数据。
+* 支持 String 列类型，最大支持 2GB 。
+* 支持 List 分区功能，可以针对枚举值创建分区。
+* 支持事务性 Insert 语句功能。可以通过 begin ; insert ; insert; ,... ; commit ; 的方式批量导入数据。
+* 支持在 Unique Key 模型上的 Update 语句功能。可以在 Unique Key 模型表上执行 Update Set where 语句。
+* 支持 SQL 阻塞名单功能。可以通过正则、Hash 值匹配等方式阻止部分 SQL 的执行。
+* 支持 LDAP 登陆验证。
+
+### 拓展功能
+
+* 支持 Flink-Doris-Connector 。
+* 支持 DataX doriswriter 插件。
+* Spark-Doris-Connector 支持数据写入 Doris 。
+
+
+## 功能优化
+
+### 查询
+
+* 支持在 SQL 查询规划阶段，利用 BE 的函数计算能力计算所有常量表达式。
+
+### 导入
+
+* 支持导入文本格式文件时，指定多字节行列分隔符或不可见分隔符。
+* 支持通过 Stream Load 导入压缩格式文件。
+* Stream Load支持导入多行格式的 Json 数据。
+
+### 导出
+
+* 支持 Export 导出功能指定 where 过滤条件。支持导出文件使用多字节行列分隔符。支持导出到本地文件。
+* Export 导出功能支持仅导出指定的列。
+* 支持通过 outfile 语句导出结果集到本地磁盘，并支持导出后写入导出成功的标记文件。
+
+### 易用性
+
+* 动态分区功能支持创建、保留指定的历史分区、支持自动冷热数据迁移设置。
+* 支持在命令行使用可视化的树形结构展示查询、导入的计划和 Profile。
+* 支持记录并查看 Stream Load 操作日志。
+* 通过 Routine Load 消费 Kafka 数据时，可以指定时间点进行消费。
+* 支持通过 show create routine load 功能导出 Routine Load 的创建语句。
+* 支持通过 pause/resume all routine load 命令一键启停所有 Routine Load Job。
+* 支持通过 alter routine load 语句修改 Routine Load 的 Broker List 和 Topic。
+* 支持 create table as select 功能。
+* 支持通过 alter table 命令修改列注释和表注释。
+* show tablet status 增加表创建时间、数据更新时间。
+* 支持通过 show data skew 命令查看表的数据量分布，以排查数据倾斜问题。
+* 支持通过 show/clean trash 命令查看 BE 文件回收站的磁盘占用情况并主动清除。
+* 支持通过 show view 语句展示一个表被哪些视图所引用。
+
+### 新增函数
+
+* `bitmap_min`, `bit_length`
+* `yearweek`, `week`, `makedate`
+* `percentile` 精确百分位函数
+* `json_array`，`json_object`，`json_quote`
+* 支持为 `AES_ENCRYPT` 和 `AES_DECRYPT` 函数创建自定义公钥。
+* 支持通过 `create alias function` 创建函数别名来组合多个函数。
+
+### 其他
+
+* 支持访问 SSL 连接协议的ES外表。
+* 支持在动态分区属性中指定热点分区的数量，热点分区将存储在 SSD 磁盘中。
+* 支持通过 Broker Load 导入 Json 格式数据。
+* 支持直接通过 libhdfs3 库访问 HDFS 进行数据的导入导出，而不需要 Broker 进程。
+* select into outfile 功能支持导出 Parquet 文件格式，并支持并行导出。
+* ODBC 外表支持 SQLServer。
