+# DorisWriter 插件文档
+
+## 1 快速介绍
+DorisWriter支持将大批量数据写入Doris中。
+
+## 2 实现原理
+DorisWriter 通过Doris原生支持Stream load方式导入数据， DorisWriter会将`reader`读取的数据进行缓存在内存中，拼接成Json文本，然后批量导入至Doris。
+
+## 3 功能说明
+
+### 3.1 配置样例
+
+这里是一份从Stream读取数据后导入至Doris的配置文件。

+### 3.2 参数说明
+
+* **jdbcUrl**
+
+    - 描述：Doris 的 JDBC 连接串，用户执行 preSql 或 postSQL。
+    - 必选：是
+    - 默认值：无
+
+* **loadUrl**
+
+  - 描述：作为 Stream Load 的连接目标。格式为 "ip:port"。其中 IP 是 FE 节点 IP，port 是 FE 节点的 http_port。可以填写多个，多个之间使用英文状态的分号隔开:`;`，doriswriter 将以轮询的方式访问。
+  - 必选：是
+  - 默认值：无
+
+* **username**
+
+    - 描述：访问Doris数据库的用户名
+    - 必选：是
+    - 默认值：无
+    
+* **password**
+  
+    - 描述：访问Doris数据库的密码
+    - 必选：否
+    - 默认值：空
+
+* **connection.selectedDatabase**
+    - 描述：需要写入的Doris数据库名称。
+    - 必选：是
+    - 默认值：无
+    
+* **connection.table**
+  - 描述：需要写入的Doris表名称。
+    - 必选：是
+    - 默认值：无
+    
+* **column**
+
+    - 描述：目的表**需要写入数据**的字段，这些字段将作为生成的 Json 数据的字段名。字段之间用英文逗号分隔。例如: "column": ["id","name","age"]。
+    - 必选：是
+    - 默认值：否
+
+* **preSql**
+
+  - 描述：写入数据到目的表前，会先执行这里的标准语句。
+  - 必选：否
+  - 默认值：无
+
+* **postSql**
+
+  - 描述：写入数据到目的表后，会执行这里的标准语句。
+  - 必选：否
+  - 默认值：无
+
+
+* **maxBatchRows**
+
+  - 描述：每批次导入数据的最大行数。和 **maxBatchSize** 共同控制每批次的导入数量。每批次数据达到两个阈值之一，即开始导入这一批次的数据。
+  - 必选：否
+  - 默认值：500000
+
+* **batchSize**
+
+  - 描述：每批次导入数据的最大数据量。和 **maxBatchRows** 共同控制每批次的导入数量。每批次数据达到两个阈值之一，即开始导入这一批次的数据。
+  - 必选：否
+  - 默认值：104857600
+
+* **maxRetries**
+
+  - 描述：每批次导入数据失败后的重试次数。
+  - 必选：否
+  - 默认值：0
+
+* **labelPrefix**
+
+  - 描述：每批次导入任务的 label 前缀。最终的 label 将有 `labelPrefix + UUID` 组成全局唯一的 label，确保数据不会重复导入
+  - 必选：否
+  - 默认值：`datax_doris_writer_`
+
+* **loadProps**
+
+  - 描述：StreamLoad 的请求参数，详情参照StreamLoad介绍页面。[Stream load - Apache Doris](https://doris.apache.org/zh-CN/docs/data-operate/import/import-way/stream-load-manual)
+
+    这里包括导入的数据格式：format等，导入数据格式默认我们使用csv，支持JSON，具体可以参照下面类型转换部分，也可以参照上面Stream load 官方信息
+
+  - 必选：否
+
+  - 默认值：无
+
+### 类型转换
+
+默认传入的数据均会被转为字符串，并以`\t`作为列分隔符，`\n`作为行分隔符，组成`csv`文件进行StreamLoad导入操作。
+
+默认是csv格式导入，如需更改列分隔符， 则正确配置 `loadProps` 即可：
+
+```json
+"loadProps": {
+    "column_separator": "\\x01",
+    "row_delimiter": "\\x02"
+}
+```
+
+如需更改导入格式为`json`， 则正确配置 `loadProps` 即可：
+```json
+"loadProps": {
+    "format": "json",
+    "strip_outer_array": true
+}
+```
+
