<h3>Reading from an SQS queue</h3>
<p>The <a href="../../../../../../../org/apache/beam/sdk/io/aws/sqs/SqsIO.html" title="class in org.apache.beam.sdk.io.aws.sqs"><code>SqsIO</code></a> <a href="../../../../../../../org/apache/beam/sdk/io/aws/sqs/SqsIO.Read.html" title="class in org.apache.beam.sdk.io.aws.sqs"><code>SqsIO.Read</code></a> returns an unbounded <a href="../../../../../../../org/apache/beam/sdk/values/PCollection.html" title="class in org.apache.beam.sdk.values"><code>PCollection</code></a> of <a href="https://static.javadoc.io/com.amazonaws/aws-java-sdk-sqs/1.12.135/com/amazonaws/services/sqs/model/Message.html?is-external=true" title="class or interface in com.amazonaws.services.sqs.model"><code>Message</code></a> containing the received messages. Note: This source
does not currently advance the watermark when no new messages are received.
<p>To configure an SQS source, you have to provide the queueUrl to connect to. The following
example illustrates how to configure the source:
<pre><code>
pipeline.apply(SqsIO.read().withQueueUrl(queueUrl))
</code></pre>
<h3>Writing to an SQS queue</h3>
<p>The following example illustrates how to use the sink:
<pre><code>
pipeline
.apply(...) // returns PCollection&lt;SendMessageRequest&gt;
.apply(SqsIO.write())
</code></pre>
<h3>Additional Configuration</h3>
<p>Additional configuration can be provided via <a href="../../../../../../../org/apache/beam/sdk/io/aws/options/AwsOptions.html" title="interface in org.apache.beam.sdk.io.aws.options"><code>AwsOptions</code></a> from command line args or in
code. For example, if you wanted to provide a secret access key via code:
<pre><code>
PipelineOptions pipelineOptions = PipelineOptionsFactory.fromArgs(args).withValidation().create();
AwsOptions awsOptions = pipelineOptions.as(AwsOptions.class);
BasicAWSCredentials awsCreds = new BasicAWSCredentials("accesskey", "secretkey");
awsOptions.setAwsCredentialsProvider(new AWSStaticCredentialsProvider(awsCreds));
Pipeline pipeline = Pipeline.create(options);
</code></pre>
<p>For more information on the available options see <a href="../../../../../../../org/apache/beam/sdk/io/aws/options/AwsOptions.html" title="interface in org.apache.beam.sdk.io.aws.options"><code>AwsOptions</code></a>.</div>
