 TDengine has a native distributed design and provides the ability to scale out. A few nodes can form a TDengine cluster. If you need higher processing power, you just need to add more nodes into the cluster. TDengine uses virtual node technology to virtualize a node into multiple virtual nodes to achieve load balancing. At the same time, TDengine can group virtual nodes on different nodes into virtual node groups, and use the replication mechanism to ensure the high availability of the system. The cluster feature of TDengine is completely open source.

+
+By using the RJDBC library in R, you can enable R programs to access TDengine data. Here are the installation process, configuration steps, and an example code in R.
+
+## Installation Process
+
+Before getting started, make sure you have installed the R language environment. Then, follow these steps to install and configure the RJDBC library:
+
+1. Install Java Development Kit (JDK): RJDBC library requires Java environment. Download the appropriate JDK for your operating system from the official Oracle website and follow the installation guide.
+
+2. Install the RJDBC library: Execute the following command in the R console to install the RJDBC library.
+
+```r
+install.packages("RJDBC", repos='http://cran.us.r-project.org')
+```
+
+:::note
+1. The default R language package version 4.2 which shipped with Ubuntu might lead unresponsive bug. Please install latest version of R language package from the [official website](https://www.r-project.org/).
+2. On Linux systems, installing the RJDBC package may require installing the necessary components for compilation. For example, on Ubuntu, you can execute the command ``apt install -y libbz2-dev libpcre2-dev libicu-dev`` to install the required components.
+3. On Windows systems, you need to set the **JAVA_HOME** environment variable.
+:::
+
+3. Download the TDengine JDBC driver: Visit the Maven website and download the TDengine JDBC driver (taos-jdbcdriver-X.X.X-dist.jar) to your local machine.
+
+## Configuration Process
+
+Once you have completed the installation steps, you need to do some configuration to enable the RJDBC library to connect and access the TDengine time-series database.
+
+1. Load the RJDBC library and other necessary libraries in your R script:
+
+```r
+library(DBI)
+library(rJava)
+library(RJDBC)
+```
+
+2. Set the JDBC driver and JDBC URL:
+
+```r
+# Set the JDBC driver path (specify the location on your local machine)
+driverPath <- "/path/to/taos-jdbcdriver-X.X.X-dist.jar"
+
+# Set the JDBC URL (specify the FQDN and credentials of your TDengine cluster)
+url <- "jdbc:TAOS://localhost:6030/?user=root&password=taosdata"
+```
+
+3. Load the JDBC driver:
+
+```r
+# Load the JDBC driver
+drv <- JDBC("com.taosdata.jdbc.TSDBDriver", driverPath)
+```
+
+4. Create a TDengine database connection:
+
+```r
+# Create a database connection
+conn <- dbConnect(drv, url)
+```
+
+5. Once the connection is established, you can use the ``conn`` object for various database operations such as querying data and inserting data.
+
+6. Finally, don't forget to close the database connection after you are done:
+
+```r
+# Close the database connection
+dbDisconnect(conn)
+```
+
+## Example Code Using RJDBC in R
+
+Here's an example code that uses the RJDBC library to connect to a TDengine time-series database and perform a query operation:
+
+<Rdemo/>
+
+Please modify the JDBC driver, JDBC URL, username, password, and SQL query statement according to your specific TDengine time-series database environment and requirements.
+
+By following the steps and using the provided example code, you can use the RJDBC library in the R language to access the TDengine time-series database and perform tasks such as data querying and analysis.

+通过 R 语言中的 RJDBC 库可以使 R 语言程序支持访问 TDengine 数据。以下是安装过程、配置过程以及 R 语言示例代码。
+
+## 安装过程
+
+在开始之前，请确保已经安装了R语言环境。然后按照以下步骤安装和配置RJDBC库：
+
+1. 安装Java Development Kit (JDK)：RJDBC库需要依赖Java环境。请从Oracle官方网站下载适合您操作系统的JDK，并按照安装指南进行安装。
+
+2. 安装RJDBC库：在R控制台中执行以下命令来安装RJDBC库。
+
+```r
+install.packages("RJDBC", repos='http://cran.us.r-project.org')
+```
+
+:::note
+1. Ubuntu 系统自带的 R 语言软件版本 4.2 在调用 RJDBC 库会产生无响应 bug，请安装 R 语言[官网](https://www.r-project.org/)的安装包。
+2. 在 Linux 上安装 RJDBC 包可能需要安装编译需要的组件，以 Ubuntu 为例执行 `apt install -y libbz2-dev libpcre2-dev libicu-dev` 命令安装。
+3. 在 Windows 系统上需要设置 JAVA_HOME 环境变量。
+:::
+
+3. 下载 TDengine JDBC 驱动程序：访问 maven.org 网站，下载 TDengine JDBC 驱动程序（taos-jdbcdriver-X.X.X-dist.jar）。
+
+4. 将 TDengine JDBC 驱动程序放置在适当的位置：在您的计算机上选择一个合适的位置，将 TDengine JDBC 驱动程序文件（taos-jdbcdriver-X.X.X-dist.jar）保存在此处。
+
+## 配置过程
+
+完成了安装步骤后，您需要进行一些配置，以便RJDBC库能够正确连接和访问TDengine时序数据库。
+
+1. 在 R 脚本中加载 RJDBC 和其他必要的库：
+
+```r
+library(DBI)
+library(rJava)
+library(RJDBC)
+```
+
+2. 设置 JDBC 驱动程序和 JDBC URL：
+
+```r
+# 设置JDBC驱动程序路径（根据您实际保存的位置进行修改）
+driverPath <- "/path/to/taos-jdbcdriver-X.X.X-dist.jar"
+
+# 设置JDBC URL（根据您的具体环境进行修改）
+url <- "jdbc:TAOS://localhost:6030/?user=root&password=taosdata"
+```
+
+3. 加载 JDBC 驱动程序：
+
+```r
+# 加载JDBC驱动程序
+drv <- JDBC("com.taosdata.jdbc.TSDBDriver", driverPath)
+```
+
+4. 创建 TDengine 数据库连接：
+
+```r
+# 创建数据库连接
+conn <- dbConnect(drv, url)
+```
+
+5. 连接成功后，您可以使用 conn 对象进行各种数据库操作，如查询数据、插入数据等。
+
+6. 最后，不要忘记在使用完成后关闭数据库连接：
+
+```r
+# 关闭数据库连接
+dbDisconnect(conn)
+```
+
+## 使用 RJDBC 的 R 语言示例代码
+
+以下是一个使用 RJDBC 库连接 TDengine 时序数据库并执行查询操作的示例代码：
+
+<Rdemo/>
+
+请根据您的实际情况修改JDBC驱动程序、JDBC URL、用户名、密码以及SQL查询语句，以适配您的 TDengine 时序数据库环境和要求。
+
+通过以上步骤和示例代码，您可以在 R 语言环境中使用 RJDBC 库访问 TDengine 时序数据库，进行数据查询和分析等操作。

 TDengine 支持集群，提供水平扩展的能力。如果需要获得更高的处理能力，只需要多增加节点即可。TDengine 采用虚拟节点技术，将一个节点虚拟化为多个虚拟节点，以实现负载均衡。同时，TDengine可以将多个节点上的虚拟节点组成虚拟节点组，通过多副本机制，以保证供系统的高可用。TDengine的集群功能完全开源。

+## Geometry 函数
+
+### Geometry 输入函数：
+
+#### ST_GeomFromText
+
+```sql
+ST_GeomFromText(VARCHAR WKT expr)
+```
+
+**功能说明**：根据 Well-Known Text (WKT) 表示从指定的几何值创建几何数据。
+
+**返回值类型**：GEOMETRY
+
+**适用数据类型**：VARCHAR
+
+**适用表类型**：标准表和超表
+
+**使用说明**：输入可以是 WKT 字符串之一，例如点（POINT）、线串（LINESTRING）、多边形（POLYGON）、多点集（MULTIPOINT）、多线串（MULTILINESTRING）、多多边形（MULTIPOLYGON）、几何集合（GEOMETRYCOLLECTION）。输出是以二进制字符串形式定义的 GEOMETRY 数据类型。
+
+### Geometry 输出函数：
+
+#### ST_AsText
+
+```sql
+ST_AsText(GEOMETRY geom)
+```
+
+**功能说明**：从几何数据中返回指定的 Well-Known Text (WKT) 表示。
+
+**返回值类型**：VARCHAR
+
+**适用数据类型**：GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**：输出可以是 WKT 字符串之一，例如点（POINT）、线串（LINESTRING）、多边形（POLYGON）、多点集（MULTIPOINT）、多线串（MULTILINESTRING）、多多边形（MULTIPOLYGON）、几何集合（GEOMETRYCOLLECTION）。
+
+### Geometry 关系函数：
+
+#### ST_Intersects
+
+```sql
+ST_Intersects(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+##功能说明**：比较两个几何对象，并在它们相交时返回 true。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**：如果两个几何对象有任何一个共享点，则它们相交。
+
+#### ST_Equals
+
+```sql
+ST_Equals(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+**功能说明**：如果给定的几何对象是"空间相等"的，则返回 TRUE。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**："空间相等"意味着 ST_Contains(A,B) = true 和 ST_Contains(B,A) = true，并且点的顺序可能不同，但表示相同的几何结构。
+
+#### ST_Touches
+
+```sql
+ST_Touches(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+**功能说明**：如果 A 和 B 相交，但它们的内部不相交，则返回 TRUE。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**：A 和 B 至少有一个公共点，并且这些公共点位于至少一个边界中。对于点/点输入，关系始终为 FALSE，因为点没有边界。
+
+#### ST_Covers
+
+```sql
+ST_Covers(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+**功能说明**：如果 B 中的每个点都位于几何形状 A 内部（与内部或边界相交），则返回 TRUE。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**：A 包含 B 意味着 B 中的没有点位于 A 的外部（在外部）。
+
+#### ST_Contains
+
+```sql
+ST_Contains(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+**功能说明**：如果 A 包含 B，描述：如果几何形状 A 包含几何形状 B，则返回 TRUE。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
+
+**使用说明**：A 包含 B 当且仅当 B 的所有点位于 A 的内部（即位于内部或边界上）（或等效地，B 的没有点位于 A 的外部），并且 A 和 B 的内部至少有一个公共点。
+
+#### ST_ContainsProperly
+
+```sql
+ST_ContainsProperly(GEOMETRY geomA, GEOMETRY geomB)
+```
+
+**功能说明**：如果 B 的每个点都位于 A 内部，则返回 TRUE。
+
+**返回值类型**：BOOL
+
+**适用数据类型**：GEOMETRY，GEOMETRY
+
+**适用表类型**：标准表和超表
