| # go-druid | ||
| A Golang client for Druid. | ||
| Now supports Query API and Common API. | ||
|
|
||
| ### Development | ||
|
|
||
| #### Testing | ||
| `go-druid` uses mage to run tests locally. | ||
| Install Mage: | ||
| ``` | ||
| git clone https://github.com/magefile/mage | ||
| cd mage | ||
| go run bootstrap.go | ||
| ``` | ||
| `mage -l` provides a list of targets that can be run. Default is `Check` | ||
|
|
||
| ``` | ||
| Targets: | ||
| build runs go mod download and then installs the binary. | ||
| check* run linters and tests | ||
| fmt run gofmt linter | ||
| lint run golint linter https://github.com/golang/lint | ||
| testCoverHTML generates test coverage report | ||
| testRace run tests with race detector | ||
