Example 1 with EventStreamIndex

use of io.muoncore.newton.query.EventStreamIndex in project newton by muoncore.

the class MuonClusterAwareTrackingSubscriptionManager method localTrackingSubscription.

private void localTrackingSubscription(String subscriptionName, String streamName, Consumer<NewtonEvent> onData, Consumer<Throwable> onError) {
    EventStreamIndex eventStreamIndex = getEventStreamIndex(subscriptionName, streamName);
    Long lastSeen = eventStreamIndex.getLastSeen() + 1;
    log.info("Subscribing from index {} to event stream {} '{}'", lastSeen, subscriptionName, streamName);
    Map args = new HashMap();
    args.put("from", lastSeen);
    args.put("sub-name", subscriptionName);
    eventClient.replay(streamName, EventReplayMode.REPLAY_THEN_LIVE, args, new EventSubscriber(event -> {
        log.trace("Store is {}, event is {}, time is {}", eventStreamIndexStore, event, event.getOrderId());
        Class<? extends NewtonEvent> eventType = MuonLookupUtils.getDomainClass(event);
        if (log.isTraceEnabled()) {
            log.trace("Store is {}, event is {}, time is {}", eventStreamIndexStore, event, event.getOrderId());
        }
        eventStreamIndexStore.save(new EventStreamIndex(subscriptionName, event.getOrderId() == null ? 0l : event.getOrderId()));
        NewtonEvent newtonEvent;
        if (eventType == null) {
            newtonEvent = new EventTypeNotFound(event.getOrderId(), event);
        } else {
            newtonEvent = MuonLookupUtils.decorateMeta(event.getPayload(eventType), event);
        }
        worker.execute(() -> {
            eventStreamProcessor.executeWithinEventContext(newtonEvent, onData);
        });
    }, onError));
