+
+## 1. Requirement Background
+hiveEngineConn supports concurrency, reducing the resource consumption of starting hive engine.
+
+## 2. Instructions for use
+First, modify linkis-engineconn.properties file in linkis-engineconn-plugins/hive/src/main/resources directory,
+and set linkis.hive.engineconn.concurrent.support to true.
+```
+# support parallelism execution
+linkis.hive.engineconn.concurrent.support=true
+```
+
+Second, submit a hive task ,when first task finished ,submit another task. Your could see hive engine has been reused.  
+
+
+## 3. Precautions
+1, Submit second hive task when first task has been finished.

+title: Extend linkis-storage add support OSS filesystem
+sidebar_position: 0.2
+---
+
+## 1. Requirement Background
+Extend linkis-storage add support OSS filesystem
+
+## 2. Instructions for use
+To store log and resultSet in OSS, add the following configs in conf/linkis-cg-entrance.properties.
+```
+#eg:
+wds.linkis.entrance.config.log.path=oss://linkis/tmp/
+wds.linkis.resultSet.store.path=oss://linkis/tmp/
+wds.linkis.filesystem.hdfs.root.path=oss://taihao-linkis/tmp/
+wds.linkis.fs.oss.endpoint=https://oss-cn-hangzhou.aliyuncs.com
+wds.linkis.fs.oss.bucket.name=linkis
+wds.linkis.fs.oss.accessKeyId=your accessKeyId
+wds.linkis.fs.oss.accessKeySecret=your accessKeySecret
+```
+
+Add the following configs in engine engineconn plugins conf. Let me use hive conf for example: 
+modify linkis-engineconn-plugins/hive/src/main/resources/linkis-engineconn.properties and 
+add the following configs.
+```
+#eg:
+wds.linkis.fs.oss.endpoint=https://oss-cn-hangzhou.aliyuncs.com
+wds.linkis.fs.oss.bucket.name=linkis
+wds.linkis.fs.oss.accessKeyId=your accessKeyId
+wds.linkis.fs.oss.accessKeySecret=your accessKeySecret
+```
+
+
+## 3. Precautions
+1, you have an OSS bucket.
+2, you have accessKeyId, accessKeySecret to access the above OSS bucket.

+title: hive engine支持并发，支持复用
+sidebar_position: 0.2
+---
+
+## 1. 需求背景
+hiveEngineConn支持并发，减少启动hive引擎的资源消耗。
+
+## 2. 使用说明
+首先，在linkis-engineconn-plugins/hive/src/main/resources目录下修改linkis-engineconn.properties文件，
+并将linkis.hive.engineconn.concurrent.support设置为true。
+```
+# 支持并行执行
+linkis.hive.engineconn.concurrent.support=true
+```
+
+第二，提交一个hive任务，当第一个任务完成后，再提交另一个任务。您可以看到hive引擎已被重用。
+
+## 3. 注意事项
+1、等第一个hive任务执行成功后，再提交第二个hive任务。

+title: 扩展linkis-storage以支持OSS文件系统
+sidebar_position: 0.2
+---
+
+## 1. 需求背景
+扩展linkis-storage以支持OSS文件系统。
+
+## 2. 使用说明
+为了在OSS中存储日志和resultSet，请在conf/linkis-cg-entrance.properties中添加以下配置。示例：
+```
+wds.linkis.entrance.config.log.path=oss://linkis/tmp/
+wds.linkis.resultSet.store.path=oss://linkis/tmp/
+wds.linkis.filesystem.hdfs.root.path=oss://taihao-linkis/tmp/
+wds.linkis.fs.oss.endpoint=https://oss-cn-hangzhou.aliyuncs.com
+wds.linkis.fs.oss.bucket.name=linkis
+wds.linkis.fs.oss.accessKeyId=your accessKeyId
+wds.linkis.fs.oss.accessKeySecret=your accessKeySecret
+```
+
+在engine engineconn插件conf中添加以下配置。以hive conf为例：修改linkis-engineconn-plugins/hive/src/main/resources/linkis-engineconn.properties，
+并添加以下配置。示例：
+```
+wds.linkis.fs.oss.endpoint=https://oss-cn-hangzhou.aliyuncs.com
+wds.linkis.fs.oss.bucket.name=linkis
+wds.linkis.fs.oss.accessKeyId=your accessKeyId
+wds.linkis.fs.oss.accessKeySecret=your accessKeySecret
+```
+
+## 3. 注意事项
+1、您需要拥有一个OSS存储桶。
+2、您需要accessKeyId和accessKeySecret以访问上述OSS存储桶。
