Defines the characteristics of work queues:
<queue id="myqueue">
<name>My Queue</name>
<maxThreads>4</maxThreads>
<capacity>100</capacity>
<clearCompletedAfterSeconds>300</clearCompletedAfterSeconds>
<category>somecategory1</category>
<category>somecategory2</category>
</queue>
- id is the queue id.
- name is the human-readable name.
- maxThreads maximum number of worker threads (default 4).
- capacity when specified make the queue bounded, the scheduling of new work is blocking when the queue is full (default unlimited).
- clearCompletedAfterSeconds (default 3600) is the delay after which completed work may be automatically cleared from its queue. 0 means never.
