/** | ||
* An unbounded source for Amazon Simple Queue Service (SQS). | ||
* | ||
* <h3>Reading from an SQS queue</h3> | ||
* | ||
* <p>The {@link SqsIO} {@link Read} returns an unbounded {@link PCollection} of {@link | ||
* com.amazonaws.services.sqs.model.Message} 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)) | ||
* }</pre> | ||
* | ||
* <h3>Writing to an SQS queue</h3> | ||
* | ||
* <p>The following example illustrates how to use the sink: | ||
* | ||
* <pre>{@code | ||
* pipeline | ||
* .apply(...) // returns PCollection<SendMessageRequest> | ||
* .apply(SqsIO.write()) | ||
* }</pre> | ||
* | ||
* <h3>Additional Configuration</h3> | ||
* | ||
* <p>Additional configuration can be provided via {@link AwsOptions} 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); | ||
* }</pre> | ||
* | ||
* <p>For more information on the available options see {@link AwsOptions}. | ||
