1. Introduction

driver-go is the official Go language connector for TDengine. It implements the Go language database/sql interface, allowing Go developers to create applications that interact with TDengine clusters.

2. Documentation

  • To use Go connector, please check Developer Guide, which includes how an application can introduce the driver-go, as well as examples of data writing, querying, schemaless writing, parameter binding, and data subscription.
  • For other reference information, please check Reference Manual, which includes version history, data types, example programs, API descriptions, and FAQs.
  • This quick guide is mainly for developers who like to contribute/build/test the Go connector by themselves. To learn about TDengine, you can visit the official documentation.

3. Prerequisites

System Requirements

  • Go >= 1.14 (1.23+ recommended)
  • For native connector: TDengine client library (libtaos.so)
  • For REST/WebSocket connector: no native library needed

Installing Go

Ubuntu/Debian & CentOS/RHEL:

wget https://go.dev/dl/go1.23.4.linux-amd64.tar.gz
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.23.4.linux-amd64.tar.gz
export PATH=/usr/local/go/bin:$PATH

Native Connector Notes

  • Enable CGO with export CGO_ENABLED=1 when building or testing the native connector.
  • Ensure libtaos.so is installed in a standard library search path, or set LD_LIBRARY_PATH accordingly.

Local Test Environment

  • TDengine has been deployed locally. For specific steps, please refer to Deploy TDengine. Please make sure taosd and taosAdapter have been started.

4. Building

git clone https://github.com/taosdata/driver-go.git
cd driver-go
go build ./...   # verify compilation

driver-go is a Go library, so go build ./... is the standard way to verify that all packages compile successfully.

5. Testing

5.1 Test Execution

  1. Before running tests, ensure that the TDengine server is installed and that taosd and taosAdapter are running. The database should be empty.
  2. In the project directory, run go test ./... to execute the tests. The tests will connect to the local TDengine server and taosAdapter for testing.
  3. The output result PASS means the test passed, while FAIL means the test failed. For detailed information, run go test -v ./....
# run the full test suite
go test ./...

# run with verbose output
go test -v ./...
  • Native connector tests require CGO enabled and a working libtaos.so installation.
  • REST/WebSocket tests do not require the TDengine native client library, but still require running taosd and taosAdapter.

5.2 Test Case Addition

Add test cases to the *_test.go file to ensure that the test cases cover the new code.

5.3 Performance Testing

Performance testing is in progress.

6. Packaging

driver-go is a Go module — no separate packaging step needed. Users import it via:

go get github.com/taosdata/driver-go/v3@latest

7. CI/CD
