Example 1 with PipelineExecutor

use of org.apache.flink.core.execution.PipelineExecutor in project flink by apache.

the class StreamExecutionEnvironment method execute.

/**
 * Triggers the program execution. The environment will execute all parts of the program that
 * have resulted in a "sink" operation. Sink operations are for example printing results or
 * forwarding them to a message queue.
 *
 * @param streamGraph the stream graph representing the transformations
 * @return The result of the job execution, containing elapsed time and accumulators.
 * @throws Exception which occurs during job execution.
