Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions,
see Getting Started with Amazon Web Services in China
(PDF).
Amazon Redshift will no longer support the creation of new Python UDFs starting November 1, 2025.
If you would like to use Python UDFs, create the UDFs prior to that date.
Existing Python UDFs will continue to function as normal. For more information, see the
blog post

Hello Amazon Redshift
The following code examples show how to get started using Amazon Redshift.
- Go
-
- SDK for Go V2
-
package main
import (
"context"
"fmt"
"github.com/aws/aws-sdk-go-v2/aws"
"github.com/aws/aws-sdk-go-v2/config"
"github.com/aws/aws-sdk-go-v2/service/redshift"
)
// main uses the AWS SDK for Go V2 to create a Redshift client
// and list up to 10 clusters in your account.
// This example uses the default settings specified in your shared credentials
// and config files.
func main() {
ctx := context.Background()
sdkConfig, err := config.LoadDefaultConfig(ctx)
if err != nil {
fmt.Println("Couldn't load default configuration. Have you set up your AWS account?")
fmt.Println(err)
return
}
redshiftClient := redshift.NewFromConfig(sdkConfig)
count := 20
fmt.Printf("Let's list up to %v clusters for your account.\n", count)
result, err := redshiftClient.DescribeClusters(ctx, &redshift.DescribeClustersInput{
MaxRecords: aws.Int32(int32(count)),
})
if err != nil {
fmt.Printf("Couldn't list clusters for your account. Here's why: %v\n", err)
return
}
if len(result.Clusters) == 0 {
fmt.Println("You don't have any clusters!")
return
}
for _, cluster := range result.Clusters {
fmt.Printf("\t%v : %v\n", *cluster.ClusterIdentifier, *cluster.ClusterStatus)
}
}
