getNumberOfPendingRequests, handleFailedResponse, handleSuccessfulResponse, shutDown
public ThreadInfoRequestCoordinator(Executor executor, java.time.Duration requestTimeout)
executor- Used to execute the futures.
requestTimeout- Time out after the expected sampling duration. This is added to the expected duration of a request, which is determined by the number of samples and the delay between each sample.
public CompletableFuture<JobVertexThreadInfoStats> triggerThreadInfoRequest(Map<ExecutionAttemptID,CompletableFuture<TaskExecutorThreadInfoGateway>> executionWithGateways, int numSamples, java.time.Duration delayBetweenSamples, int maxStackTraceDepth)
numSamples, collected with
delayBetweenSamplesmilliseconds delay between them.
executionWithGateways- Execution vertices together with TaskExecutors running them.
numSamples- Number of thread info samples to collect from each subtask.
delayBetweenSamples- Delay between consecutive samples (ms).
maxStackTraceDepth- Maximum depth of the stack traces collected within thread info samples.
