Class DocumentCleanupStufferThread

  • All Implemented Interfaces:
    java.lang.Runnable
    public class DocumentCleanupStufferThread
extends java.lang.Thread
    This class looks for documents that need to be deleted (as part of an end-of-job cleanup), and queues them up for the various document cleanup threads to take care of. To do this, this thread performs a query which returns a chunk of results, then queues those results. The individual document delete threads will be waiting on the queue. Once the queue is full enough, the thread then sleeps until the delete queue is empty again.
