Example 1 with TaskUpdateRequest

use of io.trino.server.TaskUpdateRequest in project trino by trinodb.

the class HttpRemoteTask method sendUpdate.

private synchronized void sendUpdate() {
    TaskStatus taskStatus = getTaskStatus();
    // don't update if the task hasn't been started yet or if it is already finished
    if (!started.get() || !needsUpdate.get() || taskStatus.getState().isDone()) {
        return;
    }
    // currentRequest is always cleared when request is complete
    if (currentRequest != null) {
        return;
    }
    // if throttled due to error, asynchronously wait for timeout and try again
    ListenableFuture<Void> errorRateLimit = updateErrorTracker.acquireRequestPermit();
    if (!errorRateLimit.isDone()) {
        errorRateLimit.addListener(this::sendUpdate, executor);
        return;
    }
    List<SplitAssignment> splitAssignments = getSplitAssignments();
    VersionedDynamicFilterDomains dynamicFilterDomains = outboundDynamicFiltersCollector.acknowledgeAndGetNewDomains(sentDynamicFiltersVersion);
    // Workers don't need the embedded JSON representation when the fragment is sent
    Optional<PlanFragment> fragment = sendPlan.get() ? Optional.of(planFragment.withoutEmbeddedJsonRepresentation()) : Optional.empty();
    TaskUpdateRequest updateRequest = new TaskUpdateRequest(session.toSessionRepresentation(), session.getIdentity().getExtraCredentials(), fragment, splitAssignments, outputBuffers.get(), dynamicFilterDomains.getDynamicFilterDomains());
    byte[] taskUpdateRequestJson = taskUpdateRequestCodec.toJsonBytes(updateRequest);
    if (fragment.isPresent()) {
        stats.updateWithPlanBytes(taskUpdateRequestJson.length);
    }
    if (!dynamicFilterDomains.getDynamicFilterDomains().isEmpty()) {
        stats.updateWithDynamicFilterBytes(taskUpdateRequestJson.length);
    }
    HttpUriBuilder uriBuilder = getHttpUriBuilder(taskStatus);
    Request request = preparePost().setUri(uriBuilder.build()).setHeader(HttpHeaders.CONTENT_TYPE, MediaType.JSON_UTF_8.toString()).setBodyGenerator(createStaticBodyGenerator(taskUpdateRequestJson)).build();
    updateErrorTracker.startRequest();
    ListenableFuture<JsonResponse<TaskInfo>> future = httpClient.executeAsync(request, createFullJsonResponseHandler(taskInfoCodec));
    currentRequest = future;
    currentRequestStartNanos = System.nanoTime();
    // The needsUpdate flag needs to be set to false BEFORE adding the Future callback since callback might change the flag value
    // and does so without grabbing the instance lock.
    needsUpdate.set(false);
    Futures.addCallback(future, new SimpleHttpResponseHandler<>(new UpdateResponseHandler(splitAssignments, dynamicFilterDomains.getVersion()), request.getUri(), stats), executor);
