Examples

The following example demonstrates how to publish message on a topic. First initialize cache.

ICache cache = CacheManager.GetCache("demoCache");

Then get messaging service from cache.

IMessagingService messagingService=cache.MessagingService;

Then get topic from messagingService

ITopic topic=messagingService.GetTopic("mytopic");  
if(topic==null)  //If topic not exists create it.
{
  topic=messagingService.CreateTopic("mytopic");
}

Then create multiple Message and DeliveryOption Tuples and store in a Collection.

List<Tuple<Message, DeliveryOption>> messagesList = new List<Tuple<Message, DeliveryOption>>();
for(int i = 0; i < 10; i++) {
    object payload = "mymessage" + i; 
    Message message = new Message(payload);   //creating message
    messagesList.Add(new Tuple<Message,DeliveryOption>(message,DeliveryOption.Any));
}

Now, Send the list for publishing and set the notifyDeliveryFailure according to your requirement.

topic.PublishBulk(messagesList, false); // here, no notifications for delivery failures will be received.
