| <p>An external PTransform which provides a bounded or unbounded stream of |
| integers.</p> |
| <p>Note: To use this transform, you need to start the Java expansion service. |
| Please refer to the portability documentation on how to do that. The |
| expansion service address has to be provided when instantiating this |
| transform. During pipeline translation this transform will be replaced by |
| the Java SDK’s GenerateSequence.</p> |
| <p>If you start Flink’s job server, the expansion service will be started on |
| port 8097. This is also the configured default for this transform. For a |
| different address, please set the expansion_service parameter.</p> |
| <p>For more information see: |
| - <a class="reference external" href="https://beam.apache.org/documentation/runners/flink/">https://beam.apache.org/documentation/runners/flink/</a> |
| - <a class="reference external" href="https://beam.apache.org/roadmap/portability/">https://beam.apache.org/roadmap/portability/</a></p> |
| <p>Note: Runners need to support translating Read operations in order to use |
| this source. At the moment only the Flink Runner supports this.</p> |
| <p>Experimental; no backwards compatibility guarantees.</p> |
