Why does HazelcastSedaConsumer no implement ShutdownAware interface
in Camel
I wanted to know why the HazelCastSedaConsumer the 2.x or 3.x version does
not implement ShutdownAware interface which is implemented by
Camel-SedaConsumer
<http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/component/seda/SedaConsumer.html>
.
We wanted to automate the gracelshutdown feature of one our services which
uses Camel and Hazelcast but we are blocked because we cannot find the
pendingInflightExchanges.We can extend the consumer where we implement that
service and maintaining the exchange count separately but it would have
been good if the Hazelcast themselves were implemented
But before beginning our implementation I wanted to know if there is a
specific reason for not implementing it or it was a miss

Thanks & Regards

Hi,
that's exatly the point. If you use Hazelcast (for seda queing), you'll do
it, because need the cluster functionality. If you don't need that - don't
use the Hazelcast component for this case. If you need a cluster, then you
'll have normally more than one node. When you shut down one of them, it
should not wait on pending exchanges, because the active nodes can handle
those.

Hi
Oh could it also be that the seda queue is clusteted, and if you
shutdown one node, you want other nodes to continue as-is, and the
node being shutdown should not wait for pending messages on the queue
to complete first.
The regular seda queue is pure internal and therefore it makes sense
it drain and process those messages as part of its shutdown. But for a
clustered queue its a different story.

Hi
I am not aware of any specific reason. And if there was one, then I
prefer to write code comments or in the class javadoc about such
reason.
We love contributions so you are welcome to log a JIRA and work on a
patch to implement this.
