<h3>Writing to SNS</h3>
<p>Example usage:
<pre><code>
PCollection&lt;PublishRequest&gt; data = ...;
data.apply(SnsIO.write()
.withTopicName("topicName")
.withRetryConfiguration(
SnsIO.RetryConfiguration.create(
4, org.joda.time.Duration.standardSeconds(10)))
.withAWSClientsProvider(new BasicSnsProvider(accessKey, secretKey, region))
.withResultOutputTag(results));
</code></pre>
<p>As a client, you need to provide at least the following things:
<ul>
<li>name of the SNS topic you're going to write to
<li>retry configuration
<li>need to specify AwsClientsProvider. You can pass on the default one BasicSnsProvider
<li>an output tag where you can get results. Example in SnsIOTest
</ul>
<p>By default, the output PublishResult contains only the messageId, all other fields are null.
If you need the full ResponseMetadata and SdkHttpMetadata you can call <a href="../../../../../../../org/apache/beam/sdk/io/aws/sns/SnsIO.Write.html#withFullPublishResult--"><code>SnsIO.Write.withFullPublishResult()</code></a>. If you need the HTTP status code but not the response headers you
can call <a href="../../../../../../../org/apache/beam/sdk/io/aws/sns/SnsIO.Write.html#withFullPublishResultWithoutHeaders--"><code>SnsIO.Write.withFullPublishResultWithoutHeaders()</code></a>.</div>
