Creating an Amazon DynamoDB Table

The following example uses the DynamoDB CreateTable operation to create the table Music your default region.

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

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

    "fmt"
    "os"
)

Initialize a session that the SDK will use to load credentials from the shared credentials file ~/.aws/credentials and region from the shared configuration file ~/.aws/config, and create the DynamoDB client.

// Initialize a session that the SDK will use to load
// credentials from the shared credentials file ~/.aws/credentials
// and region from the shared configuration file ~/.aws/config.
sess := session.Must(session.NewSessionWithOptions(session.Options{
    SharedConfigState: session.SharedConfigEnable,
}))

// 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.

// Create table Movies
tableName := "Movies"

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(tableName),
}

_, 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", tableName)
