Hi!
I need a reliable timeout mechanism within the message broker. I thought about using the nodes aggregate request and reply to implement the timeout functionality.
The timer will have to run till to 3 hours.
Is this a good idea to use these nodes, are they usable for this purpose?
Are there any inconveniences with these nodes?
Has somebody done already something similar?
What could be a nicer solution?
Best regards |

Brover V6 has two new timout nodes, but I'm not sure whether they would help you. Can you explain in more detail what you are trying to accomplish?

We are using broker version 5.
I need a timeout mechanisim for the following issue:
The broker receives messages one after another. they are stored into a db. when all messages (is a fixed value) have been received the broker goes on with the processing of these messages (the messages are read from the db). please don't question this point - it has to be like that.
when not all messages are received - whatever the reason is - the processing has to go on anyway. that's the case i need a timeout mechansim. after 2 hours the processing of the messages that are stored into the db has to continue in spite of that not all have been received. |

with v5, I think your options are limited to;
1. writing a custom plugin node to do this -or-
2. using some external event to drive a flow after two hours.
with v6 (available Sept 30th), this is exactly what timeout nodes are provided for. You can set a timer to go off in two hours, if you get all your messages, you can cancel the timer, if not, it would go off and drive a message flow of your choosing.

| I think in the current situation (with v5.0) you should use the Aggregation nodes and try, set the timer to two hours starting the moment the first message is received.... |

Does the last message distinguish itself from the others?
Is there a count available of the total number of messages ? |
