Creating an Amazon DynamoDB Table Using the AWS SDK for Go

The following example uses the DynamoDBCreateTable operation to create the table Music in the us-west-2 region.

Create the file dynamodb_create_table.go. Add the following statements to import the Go and AWS SDK for Go packages used in the example.

import (
    "fmt"
    "os"

    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/dynamodb"
)

Initialize the session that the SDK uses to load credentials from the shared credentials file ~/.aws/credentials, and create a new DynamoDB service client.

sess, err := session.NewSession(&aws.Config{
    Region: aws.String("us-west-2")},
)

// Create DynamoDB client
svc := dynamodb.New(sess)

Call CreateTable. If an error occurs, print the error and exit. If no error occurs, print an message that the table was created.

input := &dynamodb.CreateTableInput{
    AttributeDefinitions: []*dynamodb.AttributeDefinition{
        {
            AttributeName: aws.String("year"),
            AttributeType: aws.String("N"),
        },
        {
            AttributeName: aws.String("title"),
            AttributeType: aws.String("S"),
        },
    },
    KeySchema: []*dynamodb.KeySchemaElement{
        {
            AttributeName: aws.String("year"),
            KeyType:       aws.String("HASH"),
        },
        {
            AttributeName: aws.String("title"),
            KeyType:       aws.String("RANGE"),
        },
    },
    ProvisionedThroughput: &dynamodb.ProvisionedThroughput{
        ReadCapacityUnits:  aws.Int64(10),
        WriteCapacityUnits: aws.Int64(10),
    },
    TableName: aws.String("Movies"),
}

_, err = svc.CreateTable(input)

if err != nil {
    fmt.Println("Got error calling CreateTable:")
    fmt.Println(err.Error())
    os.Exit(1)
}

fmt.Println("Created the table Movies in us-west-2")
