Listing all Amazon DynamoDB Tables

The following example uses the DynamoDB ListTables operation to list all of the tables in your default region.

Create the file DynamoDBListTables.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/awserr" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/dynamodb" "fmt" )

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 a new DynamoDB service 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 ListTables. If an error occurs, print the error and exit. If no error occurs, loop through the tabless, printing the name of each table.

// create the input configuration instance input := &dynamodb.ListTablesInput{} fmt.Printf("Tables:\n") for { // Get the list of tables result, err := svc.ListTables(input) if err != nil { if aerr, ok := err.(awserr.Error); ok { switch aerr.Code() { case dynamodb.ErrCodeInternalServerError: fmt.Println(dynamodb.ErrCodeInternalServerError, aerr.Error()) default: fmt.Println(aerr.Error()) } } else { // Print the error, cast err to awserr.Error to get the Code and // Message from an error. fmt.Println(err.Error()) } return } for _, n := range result.TableNames { fmt.Println(*n) } // assign the last read tablename as the start for our next call to the ListTables function // the maximum number of table names returned in a call is 100 (default), which requires us to make // multiple calls to the ListTables function to retrieve all table names input.ExclusiveStartTableName = result.LastEvaluatedTableName if result.LastEvaluatedTableName == nil { break } }
