title: Connector
---

TDengine provides a rich set of APIs (application development interface). To facilitate users to develop their applications quickly, TDengine supports connectors for multiple programming languages, including official connectors for C/C++, Java, Python, Go, Node.js, C#, and Rust. These connectors support connecting to TDengine clusters using both native interfaces (taosc) and REST interfaces (not supported in a few languages yet). Community developers have also contributed several unofficial connectors, such as the ADO.NET connector, the Lua connector, and the PHP connector.

## Supported platforms

Currently, TDengine's native interface connectors can support platforms such as X64/X86/ARM64/ARM32/MIPS/Alpha hardware platforms and Linux/Win64/Win32 development environments. The comparison matrix is as follows.

| **CPU** | **OS** | **JDBC** | **Python** | **Go** | **Node.js** | **C#** | **Rust** | C/C++ |
| -------------- | --------- | -------- | ---------- | ------ | ----------- | ------ | -------- | ----- |
| | **X86 64bit** | **Linux** | ● | ● | ● | ● | ● | ● | ● | ●
| **X86 64bit** | **Win64** | ● | ● | ● | ● | ● | ● | ● | ●
| **X86 64bit** | **Win32** | ● | ● ● | ○ | ○ | ●
| **X86 32bit** | **Win32** | ○ | ○ | ○ | ○ | ○ | ●
| **ARM64** | **Linux** | ● | ● ● | ○ | ○ | ●
| **ARM32** | **Linux** | ● ● ● ● ● ● | ○ | ○ | ●
| **MIPS Longcore** | **Linux** | ○ | ○ | ○ | ○ | ○ | ○ | ○
| **Alpha Shenwei** | **Linux** | ○ | ○ ○ | -- | -- | --- | --- | ○ |
| **X86 Haiguang** | **Linux** | ○ | ○ | ○ | -- | -- | --- | ○ |

Where ● means the official test verification passed, ○ means the unofficial test verification passed, -- means no assurance.

Using REST connection can support a broader range of operating systems as it does not rely on client drivers.

## Version support

TDengine version updates often add new features, and the connector versions in the list are the best-fit versions of the connector.

| **TDengine Versions** | **Java** | **Python** | **Go** | **C#** | **Node.js** | **Rust** |
| --------------------- | -------- | ---------- | ------------ | ------------- | --------------- | -------- |
| **2.4.0.14 and up** | 2.0.38 | current version | develop branch | 1.0.2 - 1.0.6 | 2.0.10 - 2.0.12 | current version |
| **2.4.0.6 and up** | 2.0.37 | current version | develop branch | 1.0.2 - 1.0.6 | 2.0.10 - 2.0.12 | current version |
| **2.4.0.4 - 2.4.0.5** | 2.0.37 | current version | develop branch | 1.0.2 - 1.0.6 | 2.0.10 - 2.0.12 | current version |
| **2.2.x.x ** | 2.0.36 | current version | master branch | n/a | 2.0.7 - 2.0.9 | current version |
| **2.0.x.x ** | 2.0.34 | current version | master branch | n/a | 2.0.1 - 2.0.6 | current version |

## Functional Features

Comparing the connector support for TDengine functional features as follows.

### Using the native interface (taosc)

| **Functional Features** | **Java** | **Python** | **Go** | **C#** | **Node.js** | **Rust** |
| -------------- | -------- | ---------- | ------ | ------ | ----------- | -------- |
| **Connection Management** | Support | Support | Support | Support | Support | Support | Support
| Support | Support | Support | Support | Support | Support | Support | Support | Support
| Support | Support | Support | Support | Support | Support | Support | Support | Support
| **Parameter Binding** | Support | Support | Support | Support | Support | Support | Support
| Support | Support | Support | Support | Support | Support | Support | Not Supported
| **Schemaless** | Support | Support | Support | Support | Support | Support | Support
| **DataFrame** | Not Supported | Support | Not Supported | Not Supported | Not Supported | Not Supported

:::info
The different database framework specifications for various programming languages do not mean that all C/C++ interfaces need a wrapper.

| **DataFrame** | Not supported | Support | Not supported | N/A | Not supported | Not supported

:::warning

- Regardless of the programming language chosen for the connector, TDengine versions 2.0 and above recommend that each thread of a database application create a separate connection. Or create a connection pool based on threads to avoid interference between threads with the "USE statement" state within a connection (but the connection's query and write operations are thread-safe).

import InstallOnWindows from "./_linux_install.mdx";
import InstallOnLinux from "./_windows_install.mdx";
import VerifyWindows from "./_verify_windows.mdx";
import VerifyLinux from "./_verify_linux.mdx";

## Install Client Driver

:::info
The client driver needs to be installed if you use the native interface connector on a system that does not have the TDengine server software installed.

:::

### Installation steps

<Tabs defaultValue="linux" groupId="os">
  <TabItem value="linux" label="Linux">
    <InstallOnWindows />
  </TabItem>
  <TabItem value="windows" label="Windows">
    <InstallOnLinux />
  </TabItem>
</Tabs>

### Installation Verification

After completing the above installation and configuration and you have confirmed that the TDengine service is up and running, you can execute the TDengine CLI tool to log in.

<Tabs defaultValue="linux" groupId="os">
  <TabItem value="linux" label="Linux">
    <VerifyLinux />
  </TabItem>
  <TabItem value="windows" label="Windows">
    <VerifyWindows />
  </TabItem>
</Tabs>
