aws-sdk-go-v2 - Overriding waiter configuration per `Wait` request

Comment

// params is the input to api operation used by the waiter
params := &dynamodb.DescribeTableInput {
	TableName: aws.String("test-table")
}

// maxWaitTime is the maximum wait time, the waiter will wait for 
// the resource status.
maxWaitTime := 5 * time.Minutes

// Wait will poll until it gets the resource status, or max wait time 
// expires.
err := waiter.Wait(context.TODO(), params, maxWaitTime, func (o *dynamodb.TableExistsWaiterOptions) {

    // override minimum delay to 5 seconds
    o.MinDelay = 5 * time.Second

    // override maximum default delay to 120 seconds
    o.MaxDelay = 120 * time.Second
})
if err != nil {
    log.Printf("error: %v", err)
    return 
}
fmt.Println("Dynamodb table is now ready for write operations")
