title: Connector
description: This document describes the connectors that TDengine provides to interface with various programming languages.
---
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 and ARM hardware platforms and Linux/Windows/macOS development environments. The comparison matrix is as follows.
| **CPU** | **OS** | **Java** | **Python** | **Go** | **Node.js** | **C#** | **Rust** | C/C++ |
| -------------- | --------- | -------- | ---------- | ------ | ----------- | ------ | -------- | ----- |
| **X86 64bit** | **Linux** | ● | ● | ● | ● | ● | ● | ● |
| **X86 64bit** | **Win64** | ● | ● | ● | ● | ● | ● | ● |
| **X86 64bit** | **macOS** | ○ | ● | ● | ○ | ○ | ● | ● |
| **ARM64** | **Linux** | ● | ● | ● | ● | ○ | ○ | ● |
| **ARM64** | **macOS** | ○ | ● | ● | ○ | ○ | ● | ● |
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** |
| --------------------------- | -------------- | -------------- | -------------- | ------------- | --------------- | --------------- |
| **3.0.0.0 and later** | 3.0.2 + | latest version | 3.0 branch | 3.0.0 | 3.0.0 | current version |
| **2.4.0.14 and up ** | 2.0.38 | latest version | develop branch | 1.0.2 - 1.0.6 | 2.0.10 - 2.0.12 | current version |
| **2.4.0.4 - 2.4.0.13 ** | 2.0.37 | latest version | develop branch | 1.0.2 - 1.0.6 | 2.0.10 - 2.0.12 | current version |
| **2.2.x.x ** | 2.0.36 | latest version | master branch | n/a | 2.0.7 - 2.0.9 | current version |
| **2.0.x.x ** | 2.0.34 | latest 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 |
| **Regular Query** | Support | Support | Support | Support | Support | Support |
| **Parameter Binding** | Support | Support | Support | Support | Support | Support |
| **Subscription (TMQ)** | Support | Support | Support | Support | Support | Support |
| **Schemaless** | 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.
:::
### Use HTTP Interfaces (REST or WebSocket)
| **Functional Features** | **Java** | **Python** | **Go** | **C#** | **Node.js** | **Rust** |
| -------------------------------------- | ------------- | --------------- | ------------- | ------------- | ------------- | ------------- |
| **Connection Management** | Support | Support | Support | Support | Support | Support |
| **Regular Query** | Support | Support | Support | Support | Support | Support |
| **Parameter Binding** | Not Supported | Not Supported | Support | Support | Not Supported | Support |
| **Subscription (TMQ) ** | Supported | Support | Support | Not Supported | Not Supported | Support |
| **Schemaless** | Supported | Not Supported | Not Supported | Not Supported | Not Supported | Not Supported |
| **Bulk Pulling (based on WebSocket) ** | Support | Support | Support | Support | Support | Support |
| **DataFrame** | Not Supported | Support | Not Supported | Not Supported | 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).

## 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.
:::
### Install
### Verify
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.
