Spider REST Commands: Task Management Commands

---

Doradus Spider uses background tasks to perform data aging. These tasks execute automatically at their defined frequency. On multi-node clusters, Doradus ensures that each data-aging task is executed by only a single node at each scheduled occurrence. The following REST command is available to list the status of all known tasks: GET /_tasks This command returns a response such as the following:

    <tasks>
        <task name="Msgs/Message/data-aging">
             <Executor>127.0.0.1</Executor>
             <FinishTime>2015-02-11 14:12:32</FinishTime>
             <StartTime>2015-02-11 14:12:32</StartTime>
             <Status>Completed</Status>
        </task>
        <task name="OLAPEvents/*/data-aging">
            <Executor>127.0.0.1</Executor>
            <FinishTime>2015-02-11 14:11:31</FinishTime>
            <StartTime>2015-02-11 14:11:31</StartTime>
            <Status>Completed</Status>
        </task>
        <task name="Email/*/data-aging">
            <Executor>127.0.0.1</Executor>
            <FinishTime>2015-02-11 14:12:33</FinishTime>
