What made you chose a 1-second polling timer over the concept of calculating the delay and having an event fired at that time, though? http://ayende.com/3802/rhino-service-bus-managing-timeouts#comment3http://ayende.com/3802/rhino-service-bus-managing-timeouts#comment3Sun, 18 Jan 2009 16:45:53 GMTAyende Rahien commented on Rhino Service Bus: Managing TimeoutsWe currently keep about 64 bytes in memory for each future message. This means that for a million future messages, we are going to consume about 60 MB. That is what I referred to as potential limitation. Although I don't really consider that as a true limitation because I don't really expect to have that many future messages on a single endpoint. Timer accuracy is one second, yes. If you can think of anything that would make require lower granularity, I would like to hear about it. Duration of days / months should not be a problem, although I admit that I don't have an integration test that waits for 3 days :-) Yes, it could be implemented as retry strategy, although RSB already contains a retry strategy for messages by rolling back the transaction and retrying immediately. http://ayende.com/3802/rhino-service-bus-managing-timeouts#comment2http://ayende.com/3802/rhino-service-bus-managing-timeouts#comment2Wed, 14 Jan 2009 14:21:54 GMTRafal commented on Rhino Service Bus: Managing TimeoutsAyende, can you elaborate a bit more about this feature? - performance. Will it degrade if large number of future messages is queued? - what is the timer accuracy? 1 second? - what about long durations - days ... months? Is it a problem? - could this feature be used to implement a retry strategy for failed messages (failing messages will be rescheduled for later retry)?
