 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.

If the order is not consistent, set smlDataFormat in taos.cfg to false. Otherwise, data will be written out of order and a database error will occur.

 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。

+description: 使用 qStudio 存取 TDengine 数据的详细指南
+---
+
+qStudio 是一款免费的多平台 SQL 数据分析工具，可以轻松浏览数据库中的表、变量、函数和配置设置。最新版本 qStudio 内嵌支持 TDengine。
+
+## 前置条件
+
+使用 qStudio 连接 TDengine 需要以下几方面的准备工作。
+
+- 安装 qStudio。qStudio 支持主流操作系统包括 Windows、macOS 和 Linux。请注意[下载](https://www.timestored.com/qstudio/download/)正确平台的安装包。
+- 安装 TDengine 实例，请确认 TDengine 正常运行，并且 taosAdapter 已经安装并正常运行，具体细节请参考 [taosAdapter 的使用手册](/reference/taosadapter)。
+
+## 使用 qStudio 连接 TDengine
+
+1. 启动 qStudio 应用，从菜单项选择“Server” 和 “Add Server...”，然后在 Server Type 下拉框中选择 TDengine。
+
+ ![qStudio 连接 TDengine](./qstudio/qstudio-connect-tdengine.webp)
+
+2. 配置 TDengine 连接，填入主机地址、端口号、用户名和密码。如果 TDengine 部署在本机，可以只填用户名和密码，默认用户名为 root，默认密码为 taosdata。点击“Test”可以对连接是否可用进行测试。如果本机没有安装 TDengine Java
+ 连接器，qStudio 会提示下载安装。
+
+ ![下载 Java 连接器](./qstudio/qstudio-jdbc-connector-download.webp)
+
+3. 连接成功将显示如下图所示。如果显示连接失败，请检查 TDengine 服务和 taosAdapter 是否正确运行，主机地址、端口号、用户名和密码是否正确。
+
+ ![连接成功](./qstudio/qstudio-connect-tdengine-test.webp)
+
+4. 使用 qStudio 选择数据库和表可以浏览 TDengine 服务的数据。
+
+ ![qStudio 浏览 TDengine 数据](./qstudio/qstudio-browse-data.webp)
+
+5. 也可以通过执行 SQL 命令的方式对 TDengine 数据进行操作。
+
+ ![qStudio SQL 命令](./qstudio/qstudio-sql-execution.webp)
+
+6. qStudio 支持根据数据绘制图表等功能，请参考 [qStudio 的帮助文档](https://www.timestored.com/qstudio/help)
+
+ ![qStudio Chart 功能](./qstudio/qstudio-chart.webp)
