The Parallel Work Queue is a type of work queue that uses a number of worker threads that watch a queue and pick up an operation to process whenever one becomes available.
The parallel work queue is a FIFO queue serviced by a fixed number of worker threads. This fixed number of threads can be changed on the fly, with the change taking effect as soon as it is made. This work queue implementation is unbound ie it does not block after reaching certain queue size and as such should only be used on a very well tuned server configuration to avoid potential out of memory errors.
The Parallel Work Queue component inherits from the Work Queue
