Prerequisites

This tutorial assumes that you have:

  • installed YugabyteDB, created a universe, and are able to interact with it using the Redis shell. If not, please follow these steps in Quick start.
  • installed Go version 1.8 or later

Install the Go Redis driver

To install the driver, locally run the following go get command.

$ go get github.com/go-redis/redis

Write a HelloWorld Go application

Create a file ybredis_hello_world.go and copy the contents below.

package main;

import (
  "fmt"
  "log"

  "github.com/go-redis/redis"
)

func main() {
  // Connect to the cluster.
  client := redis.NewClient(&redis.Options{
    Addr:     "localhost:6379",
    Password: "", // no password set
    DB:       0,  // use the default DB
  })
  defer client.Close()

  // Insert some data (for user id 1).
  var userid string = "1"
  ok, err := client.HMSet(userid, map[string]interface{}{
        "name": "John",
        "age": "35",
        "language": "Redis"}).Result()

  if (err != nil) {
    log.Fatal(err)
  }
  fmt.Printf("HMSET returned '%s' for id=%s with values: name=John, age=35, language=Redis\n", ok, userid)

  // Query the data.
  result, err := client.HGetAll("1").Result()
  fmt.Printf("Query result for id=%s: '%v'\n", userid, result)
}

Run the application

To execute the file, run the following command.

$ go run ybredis_hello_world.go

You should see the following as the output.

HMSET returned 'OK' for id=1 with values: name=John, age=35, language=Redis
Query result for id=1: 'map[age:35 language:Redis name:John]'
