duckdb-go-bindings

Tests status

This repository wraps DuckDB's C API calls in Go native types and functions.

Minimum Go version: 1.24.

🚧 WORK IN PROGRESS 🚧

[!IMPORTANT]
Some type aliases and function wrappers are still missing.

Breaking changes can happen.

Releases

This module's first release contains DuckDB's v1.2.0 release.

The main module (github.com/duckdb/duckdb-go-bindings) does not link any pre-built static library.

Releasing a new duckdb version

  1. Create a new branch and update the DUCKDB_VERSION in the Makefile.
  2. Invoke the Fetch and Push Libs workflow on the new branch.
  3. Update the Releases table in the README.md.
  4. If the header (duckdb.h) has changes (non-bugfix release), add all changes (new types, functions, etc.) to the bindings.
  5. Open a PR.
  6. Wait for all tests to pass.
  7. Merge the PR into main.
  8. Publish the tags by incrementing the latest tagged release for the main module, and for each OS+architecture combination.
git tag <tagname>
git push origin <tagname>

Example PR: https://github.com/duckdb/duckdb-go-bindings/pull/19.

Using a pre-built static library

A few pre-built static libraries exist for different OS + architecture combinations. You can import these into your projects without providing additional build flags. CGO must be enabled, and your system needs a compiler available.

Here's a list:

  • github.com/duckdb/duckdb-go-bindings/...
    • darwin-amd64
    • darwin-arm64
    • linux-amd64
    • linux-arm64
    • windows-amd64

Static linking

Note that the lib(s) name must match the name provided in the CGO_LDFLAGS.
