Basic question about synchronous queues and pipes..

[lleclerc <ll...@aim-rg.com>]

Hi,

I looked into documentations/questions and I am not sure about the responses
I seen.

I want to send an http request at each 5 seconds and delay the response by 3
minutes before processing it. The http request time can vary a lot before
getting a response, but I want to keep the order intact, and process every
response in the right order.

Can it be done directly like this :

from("http4:...").delay(5000).to("direct:abc").delay(180000).process(...);

There is a queue inside direct that follow the request order ? The message
will be overwritten ?
It needs to be on 2 'from' lines? Use a different component ?


Thank you for your time !

Hi,

What you're doing is almost good. The only thing missing, if I 
understand your use case well, is a resequencer [1] that enforces the 
correct order. Doing it on separate routes is not really mandatory, but 
personally I would prefer it. I'd use either seda: or jms: for that, 
depending on how you want/need to handle potential failures.

Cheers,
Hadrian
