[jira] Created: (CAMEL-1483) Graceful shutdown
Graceful shutdown
-----------------
Key: CAMEL-1483
URL: https://issues.apache.org/activemq/browse/CAMEL-1483
Project: Apache Camel
Issue Type: New Feature
Affects Versions: 1.6.0, 2.0.0
Reporter: Claus Ibsen
Fix For: 2.1.0
Introduce a GracefulShutdownAware interface (in lack of better name) that components can support.
It allows the component to eg deny any new incoming messages.
Can be used by JMS, File, Http, Mina etc. to better support graceful shutdown as they will deny new messages.
James have a good idea on this one.

Claus Ibsen commented on CAMEL-1483:
------------------------------------
[11:15] <jstrachan> I guess for some things, its no biggie - e.g. stop all the JMS consumers and HTTP consumers first
[11:15] <jstrachan> as sending to JMS endpoints is still fine even after the JMS consumers stop
[11:15] <cibsen> yeah
[11:16] <cibsen> file consumer as well
[11:16] <jstrachan> i.e. stopping all incoming endpoints should be fine for real networked stuff (database, jms, http, mina etc)
[11:16] <jstrachan> yeah
[11:16] <jstrachan> its just in memory stuff like SEDA that its a tad tricky
[11:16] <jstrachan> so maybe we only mark things like JMS, file, database, HTTP as GracefulShutdownAware (or whatever we call it)
[11:17] <jstrachan> i.e. stuff that you can still send to after the consumer stops
[11:17] <jstrachan> then ordering doesn't matter
[11:17] <cibsen> yes good idea
[11:17] <jstrachan> then we know we really can gracefully shut down all those puppies
[11:17] <cibsen> and you should not have many messages in SEDA queus anyway as its in memory only and fast
[11:17] <jstrachan> yeah
[11:18] <jstrachan> once all the graceful stuff is shut down, we could maybe wait a bit for SEDA queues to empty up to some timeout or something
[11:18] <cibsen> so we can just give it some time to settle down before stopping
[11:18] <jstrachan> yeah
[11:18] <jstrachan> not sure if MessageListenerContainer supports graceful shutdown, we'd have to check
[11:18] <cibsen> we can use timeout for now and later support a stategy that monitors the queues and see if they are empty
[11:19] <cibsen> that one is a beast to shutdown in correct ordering with AMQ, Spring and Camel

------------------------------------
Should honor {{SuspendableService}} to suspend routes over shutdown before it waits for all the inflight exchanges to complete.
After all exchanges is complete then its shutdown for real afterwards.

Claus Ibsen commented on CAMEL-1483:
------------------------------------
We also have the inflight repository now that can inform how many messages are currently being routed.
This allows us to peek this value and wait shutting down until this value reaches zero.
There should be some form of timeout etc. to prevent deadlocking by waiting for that inflight to reach zero.
And Camel should offer a more range of shutdown operations
- shutdownNow
- shutdownGraceful
- shutdownGraceful(timeout)

Claus Ibsen commented on CAMEL-1483:
------------------------------------
I got some basic graceful shutdown up and running. Looks good so far.
I am opting for to make graceful shutdown the default in Camel and have it failsafe with a timeout that can tackle if there should be a weird situation where there are inflight exchanges which seems to never complete.
It will of course be pluggable and configurable.
It works with pending messages on seda queues and it waits for inflight exchanges to be completed.
And it stops those routes which can safely be stopped so Camel wont intake new exchanges while other routes are still routing those remaining exchanges.
There will be an interface to use by other components to indicate that they are like the seda and have pending in memory messages that Camel should wait for as well.

Claus Ibsen commented on CAMEL-1483:
------------------------------------
It would be ideal if {{Consumer}} extends {{SuspendableService}} instead of {{Service}} which would allow for a better and less bumpy graceful shutdown. As its suspended it will just block any incoming messages but still keep the remainder of the routes running. This allows with breeze to run the inflight exchanges to completion. And after this we can safely shutdown for real.
