| <div class="block">Flink job entry point to launch a Beam pipeline by executing an external SDK driver program. |
| |
| <p>Designed for non-interactive Flink REST client and container with Beam job server jar and SDK |
| client (for example when using the FlinkK8sOperator). In the future it would be possible to |
| support driver program execution in a separate (sidecar) container by introducing a client |
| environment abstraction similar to how it exists for SDK workers. |
| |
| <p>Using this entry point eliminates the need to build jar files with materialized pipeline |
| protos offline. Allows the driver program to access actual execution environment and services, on |
| par with code executed by SDK workers. |
| |
| <p>The entry point starts the job server and provides the endpoint to the the driver program. |
| |
| <p>The external driver program constructs the Beam pipeline and submits it to the job service. |
| |
| <p>The job service defers execution of the pipeline to the plan environment and returns the |
| "detached" status to the driver program. |
| |
| <p>Upon arrival of the job invocation, the entry point executes the runner, which prepares |
| ("executes") the Flink job through the plan environment. |
| |
| <p>Finally Flink launches the job.</div> |
