Yeah, I"m with Claus on this. Using a delayer for a long period of
time is not a good idea; if the JVM containing the delayer route goes
down while the message is still in memory then you'll loose the message.
Maybe a better approach might be to start a route with a timer, read
the data from a queue or database inside a custom processor, and then
do your processing?

Hi,
I would like to use the delayer pattern quite extensively to delay
quite a
few messages for up to 6 hours. Is there anyway to see how many or
even
which messages are currently delayed?
6 hours, that is a long time. I think there are settings/features
related to messaging/JMS where you can set some sort of JMS header
to indicate when its "visible" for the consumers. I would assume this
is safer as the message can stay in a persistent queue.
The delayer in Camel is a simple thread sleep feature meant for delays
in seconds. It does not have a visible queue or some sort.
I am routing from a persistent queue to the delayer and then on to
a bean. I
am worried that once a message is delayed, it will effectivley
disppaear of
my radar and I won't have a sure way to know how many messages are
currently
delayed.
Any suggestions?
Thanks
Andrew
