示例1: ensureTableExists
// ensureTableExists creates a DynamoDB table with a given
// DynamoDB client. If the table already exists, it is not
// being reconfigured.
func ensureTableExists(client *dynamodb.DynamoDB, table string, readCapacity, writeCapacity int) error {

TableName: aws.String(table),
})
if awserr, ok := err.(awserr.Error); ok {

_, err = client.CreateTable(&dynamodb.CreateTableInput{
TableName: aws.String(table),
ProvisionedThroughput: &dynamodb.ProvisionedThroughput{
