[jira] [Commented] (CAMEL-5058) Bug: Unique Endpoints Leaking in DefaultInflightRepository

["Claus Ibsen (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-5058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13221555#comment-13221555 ] 

Claus Ibsen commented on CAMEL-5058:
------------------------------------

The inflight registry should be route based instead of endpoint, as that is what the graceful shutdown really needs. 
So instead of being endpoint based, we can switch to be route id, based instead.

Can you post some more details about your use-case, I wonder why you get so many unique endpoints in the registry, as its consumer based. Are you adding a lot of new routes or the likes?

>    Affects Versions: 2.9.0

> If you have an endpoint protocol which uses unique URIs you will leak Strings in the HashMap stored in the DefaultInflightRepository (org.apache.camel.impl.DefaultInflightRepository)
> It seems there is a reference counting scheme in place, but it doesn't do a remove until the "stop" method is called to shut the system down.  We are running XMPP endpoints, which use a protocol like xmpp://someaccount@domain/password?to=someOtherAccount
> When there are 10 million accounts, not all of which are active, but all of which may message at some time or another, no references are removed to the endpointCount.
> When the count becomes 0, the reference should be removed and the size method will still return the appropriate result.
> Please be careful in the implementation to synchronize on some object (perhaps the AtomicInteger) reflecting a read/write lock on the endpoint count modification.
