There are 2 major versions of the client-go package.
-
v2is the latest stable version. This version was extracted from pingcap/tidb and it includes new TiKV features like Follower Read, 1PC, Async Commit. The development of this version is on themasterbranch. The documentation for this version is below. -
v1is the previous stable version and is only maintained for bug fixes. You can read the documentation here.
Usage/Examples
# valid versions be like @latest, @e5f932ae270887550b0cd221343dbd6b870b6c8f, @v2.0.0, @v2.0.1...

Pull Requests and issues are welcomed. Please check CONTRIBUTING.md.
Developing
Running Tests
Note: All the following tests are included in the CI and you can submit a Pull Request directly to hand over the work.
To run unit tests, use following command
go test ./...
To run code linter, make sure golangci-lint is installed. Then use following command
golangci-lint run
integration_tests can run against a real TiKV cluster. Here is an example:
./pd-server &
sleep 5
./tikv-server &
sleep 10
cd integration_tests
go test --with-tikv
Test with TiDB
It is a common task to update client-go and then test it with TiDB.
If you only need to test locally, you can directly use the modified client-go on the same host by replacing:
go mod edit -replace=github.com/tikv/client-go/v2=/path/to/client-go
If you want to push your TiDB code to GitHub for running CI or for code review, you need to change the client-go used by TiDB to your developing branch using the following steps:
go get -d github.com/GITHUB_USERNAME/client-go/v2@DEV_BRANCH
# Output:
# go get: github.com/GITHUB_USERNAME/client-go/v2@none updating to
# github.com/GITHUB_USERNAME/client-go/v2@v2.0.0-XXXXXXXXXXXXXX-XXXXXXXXXXXX: parsing go.mod:
# module declares its path as: github.com/tikv/client-go/v2
# but was required as: github.com/GITHUB_USERNAME/client-go/v2
go mod edit -replace=github.com/tikv/client-go/v2=github.com/GITHUB_USERNAME/client-go/v2@v2.0.0-XXXXXXXXXXXXXX-XXXXXXXXXXXX
go mod download github.com/tikv/client-go/v2
