[jira] [Commented] (CAMEL-6151) Add support to DirectEndpoint for blocking until a consumer is available

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

    [ https://issues.apache.org/jira/browse/CAMEL-6151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13626631#comment-13626631 ] 

Claus Ibsen commented on CAMEL-6151:
------------------------------------

The blocking behavior should only be in use if the options has been set. So its much better to in DirectEndpoint to create a producer accordingly to the options
- DirectProducer = the current default
- DirectBlockingProducer = a new which has the blocking behavior.

Then the code can be separated and avoid complicated synchronization code and whatnot.

The blocking should just loop and re-check if the consumer is there, until it either times out, or get a consumer.

> My use case is that some routes will be dynamically redployed at runtime.
> Ideally instead of retrying when a direct endpoints consumer disappears temporarily it would be nice if the direct producer would block for a configurable duration waiting for a consumer to come, back, into existence.
> The default would obviously be not to block, to maintain backwards compatibility.
> Something along these lines:
> {code}
> direct:xxxx?block=true&timeout=5000
> {code}
