Aerospike Go Client v8

An Aerospike library for Go.

This library is compatible with Go 1.23+ and supports the following operating systems: Linux, Mac OS X (Windows builds are possible, but untested).

Up-to-date documentation is available in the .

You can refer to the test files for idiomatic use cases.

Please refer to CHANGELOG.md for release notes, or if you encounter breaking changes.

Usage

The following is a very simple example of CRUD operations in an Aerospike database.

package main

import (
  "fmt"

  aero "github.com/aerospike/aerospike-client-go/v8"
)

// This is only for this example.
// Please handle errors properly.
func panicOnError(err error) {
  if err != nil {
    panic(err)
  }
}

func main() {
  // define a client to connect to
  client, err := aero.NewClient("127.0.0.1", 3000)
  panicOnError(err)

  key, err := aero.NewKey("test", "aerospike", "key")
  panicOnError(err)

  // define some bins with data
  bins := aero.BinMap{
    "bin1": 42,
    "bin2": "An elephant is a mouse with an operating system",
    "bin3": []any{"Go", 2009},
  }

  // write the bins
  err = client.Put(nil, key, bins)
  panicOnError(err)

  // read it back!
  rec, err := client.Get(nil, key)
  panicOnError(err)

  // delete the key, and check if key exists
  existed, err := client.Delete(nil, key)
  panicOnError(err)
  fmt.Printf("Record existed before delete? %v\n", existed)
}

More examples illustrating the use of the API are located in the examples directory.

Details about the API are available in the docs directory.

Prerequisites

Go version v1.23+ is required.

To install the latest stable version of Go, visit http://golang.org/dl/

Aerospike Go client implements the wire protocol, and does not depend on the C client. It is goroutine friendly, and works asynchronously.

Supported operating systems:

• Major Linux distributions (Ubuntu, Debian, Red Hat)
• Mac OS X
• Windows (untested)

Installation

1. Install Go 1.23+ as documented.
2. From a Go module, get the client: go get github.com/aerospike/aerospike-client-go/v8

• To update the client library: go get -u github.com/aerospike/aerospike-client-go/v8

Some Tips

• To run a go program directly: go run <filename.go>
• to build: go build -o <output> <filename.go>
• example: go build -tags as_performance -o benchmark tools/benchmark/benchmark.go

Performance Tweaking

We are bending all efforts to improve the client's performance. In our reference benchmarks, Go client performs almost as good as the C client.

To read about performance variables, please refer to docs/performance.md

Tests

This library is packaged with a number of tests. Tests require Ginkgo v2 and Gomega.

From a clone of this repository, update dependencies and install the test runner:

$ go install github.com/onsi/ginkgo/v2/ginkgo@latest
$ go get .

A running Aerospike Database is required. To run all test cases with race detection:

$ ginkgo -r -race -- -h 127.0.0.1 -p 3000

Examples

A variety of example applications are provided in the examples directory.

Tools

A variety of clones of original tools are provided in the tools directory. They show how to use more advanced features of the library to re-implement the same functionality in a more concise way.

Benchmarks

Benchmark utility is provided in the tools/benchmark directory. See the tools/benchmark/README.md for details.

API Documentation

A simple API documentation is available in the docs directory. The latest up-to-date docs can be found in .

Google App Engine

To build the library for App Engine, build it with the build tag app_engine. Aggregation functionality is not available in this build.

Reflection, and Object API

To make the library both flexible and fast, we had to integrate the reflection API (methods with [Get/Put/...]Object names) tightly in the library. In case you wanted to avoid mixing those API in your app inadvertently, you can use the build tag as_performance to remove those APIs from the build.
