I need to trigger an email based on an incoming message. If I get a stop message, I need to wait for 5 minutes to listen whether any start message is coming. If a start message is not received within 5 minutes, then I need to trigger an email otherwise need to discard the stop message. The message is coming in an xml format in a particular tag element.
Below is my design
stopMsg -> Compute -> TimeOutControl Node
TimeOutNotification Node -> Compute -> EmailOutput Node
When a stopMsg is received, in the compute node, I will set an environment variable, construct a timeout request and will trigger TimeOutControl Node. If a start message is received, it will send to the same compute and will check the environment variable and will override; hence discard the stopMsg. If startMsg is not received, after 5 minutes, message will be triggered to the EmailOutput node.
I request your thoughts on this design since I am using timer nodes for the first time. Also, I read that the timer nodes behave abnormally when a broker restart is performed. |

You could also use a Collector node to implement this kind of behavior.

| Many Thanks Adubya. I will have a look on its feasibility with my requirement. |

They don't behave abnormally when a flow/eg/broker restart happens.
They simply fire and you can take advantage of this to tailor your code.
Why don't you see for yourself rather than relying on the words of stranges on the internet?
1) deploy a flow with timer nodes.
2) start user trace
3) restart the EG
4) wait for a bit
5) then collect the user trace and look at the output.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |
