aws-dax-go is the official AWS DAX SDK for the Go programming language. https://aws.amazon.com/dynamodb/dax
Checkout our release notes for information about the latest bug fixes, updates, and features added to the SDK.
The best way to get started working with the SDK is to use go get to add the SDK to your Go Workspace manually.
go get github.com/aws/aws-dax-go
You could also use Dep to add the SDK to your application's dependencies. Using Dep will simplify your update story and help your application keep pinned to a specific version of the SDK.
dep ensure -add github.com/aws/aws-dax-go
This example shows how you can use the AWS DAX SDK to make an API request.
package main
import (
"fmt"
"github.com/aws/aws-dax-go/dax"
"github.com/aws/aws-sdk-go/aws"
"github.com/aws/aws-sdk-go/service/dynamodb"
)
func main() {
cfg := dax.DefaultConfig()
cfg.HostPorts = []string{"dax://mycluster.frfx8h.clustercfg.dax.usw2.amazonaws.com:8111"}
cfg.Region = "us-west-2"
client, err := dax.New(cfg)
if err != nil {
panic(fmt.Errorf("unable to initialize client %v", err))
}
//Connecion to a secure cluster
secureEndpoint := "daxs://mycluster.frfx8h.clustercfg.dax.usw2.amazonaws.com"
secureCfg := dax.DefaultConfig()
secureCfg.HostPorts = []string{secureEndpoint}
secureCfg.Region = "us-west-2"
//WARN: Skip hostname verification of TLS connections.
//The default is to perform hostname verification, setting this to True will skip verification.
//Be sure you understand the implication of doing so, which is the inability to authenticate
//the cluster that you are connecting to.
secureCfg.SkipHostnameVerification = false
// DialContext is an optional field in Config.
// If DialContext is being set in Config for a secure/ encrypted cluster, then use dax.SecureDialContext to
// return DialContext. An example of how DailContext can be set using dax.SecureDialContext is shown below.
secureCfg.DialContext = func(ctx context.Context, network string, address string) (net.Conn, error) {
// fmt.Println("Write your custom logic here")
dialCon, err := dax.SecureDialContext(secureEndpoint, secureCfg.SkipHostnameVerification)
if err != nil {
panic(fmt.Errorf("secure dialcontext creation failed %v", err))
}
return dialCon(ctx, network, address)
}
secureClient, err := dax.New(secureCfg)
if err != nil {
panic(fmt.Errorf("unable to initialize client %v", err))
}
fmt.Println("secure client created", secureClient)
input := &dynamodb.PutItemInput{
TableName: aws.String("TryDaxGoTable"),
Item: map[string]*dynamodb.AttributeValue{
"pk": {S: aws.String("mykey")},
"sk": {N: aws.String("0")},
"value": {S: aws.String("myvalue")},
},
}
output, err := client.PutItem(input)
if err != nil {
panic(fmt.Errorf("unable to make request %v", err))
}
fmt.Println("Output: ", output)
