Andrea Cosentino commented on CAMEL-10280:
------------------------------------------

We have 

{code}
        if (configuration.getTopicArn() == null) {
            // creates a new topic, or returns the URL of an existing one
            CreateTopicRequest request = new CreateTopicRequest(configuration.getTopicName());

            LOG.trace("Creating topic [{}] with request [{}]...", configuration.getTopicName(), request);

            CreateTopicResult result = snsClient.createTopic(request);
            configuration.setTopicArn(result.getTopicArn());

            LOG.trace("Topic created with Amazon resource name: {}", configuration.getTopicArn());
        }
{code}

We can add a control before creating the topic and if we have an ARN, we can skip the creation. What do you think about this approach?

>             Project: Camel
>          Issue Type: Improvement
>          Components: camel-aws
>    Affects Versions: 2.17.3, 2.18.0
>            Reporter: Stefan Fussenegger
>            Assignee: Andrea Cosentino
>
> If a topic already exists, the {{SnsEndpoint}} still requires privileges for the (idempotent) {{CreateTopic}} operation to resolve the name to an ARN.
> In comparison, the {{SqsEndpoint}} uses the {{ListQueues}} operation to check for an existing queue before trying to create a queue.
> Providing an ARN instead of a name bypasses the issue (added to 2.18 in CAMEL-9844). Using an ARN instead of a name isn't always practical though.
