Example 1 with ProactorStreamProcessingStrategy

use of org.mule.runtime.core.internal.processor.strategy.ProactorStreamProcessingStrategyFactory.ProactorStreamProcessingStrategy in project mule by mulesoft.

the class ProactorStreamProcessingStrategyTestCase method cpuIntensiveRejectedExecution.

@Test
@Description("If CPU INTENSIVE pool is busy OVERLOAD error is thrown")
public void cpuIntensiveRejectedExecution() throws Exception {
    Scheduler cpuIntensiveSchedulerSpy = spy(cpuIntensive);
    Scheduler rejectingSchedulerSpy = spy(new RejectingScheduler(cpuIntensiveSchedulerSpy));
    flow = flowBuilder.get().processors(cpuIntensiveProcessor).processingStrategyFactory((context, prefix) -> new ProactorStreamProcessingStrategy(() -> ringBuffer, DEFAULT_BUFFER_SIZE, 1, DEFAULT_WAIT_STRATEGY, () -> cpuLight, () -> blocking, () -> rejectingSchedulerSpy, 1, 2)).build();
    flow.initialise();
