delete the job immediately after reserving it or wait until Camel routes

queue”, the second is similar to “job queue”. This behavior
is controlled by <code>consumer.awaitJob</code> parameter, which
equals <code>true</code> by default (following Beanstalkd
nature).</p><p>When synchronous, the consumer
calls <code>delete</code> on successful job completion and
calls <code>bury</code> on failure. You can choose which command to
execute in the case of failure by specifying <co
de>consumer.onFailure</code> parameter in the URI. It can take values
of <code>bury</code>, <code>delete</code> or <code>release</code>.</p><p>There
is a boolean parameter <code>consumer.useBlockIO</code> which
corresponds to the same parameter in JavaBeanstalkClient library. By default it
is <code>true</code>.</p><p>Be careful when
specifying <code>release</code>, as the failed job will immediately become
available in the same tube and your consumer will try to acquire it again. You
can <code>release</code> and
specify <em>jobDelay</em> though.</p><div

failed jobs manually.</p><p>So the second route periodically requests Beanstalk

internally a scheduled poll is used to monitor some kind of state or resource

pattern to receive messages and push them through the Camel processing routes.
That is to say externally from the client the endpoint appears to use an <a

internally a scheduled poll is used to monitor some kind of state or resource
and then fire message exchanges.</p><p>Since this a such a common pattern,
polling components can extend the <a shape="rect" class="external-link"
