Bulk insert work queues

Guidewire recommends that you implement a custom work queue class that extends BulkInsertWorkQueueBase, rather than WorkQueueBase if it is possible for a query to determine the work items to create.

The use of the BulkInsertWorkQueueBase class provides the following performance optimizations:

• The work queue writer does not add duplicate entries to the work queue.
• The use of the bulk insert method eliminates the need to fetch and commit each work item individually.

As a consequence, a work queue that subclasses BulkInsertWorkQueueBase performs its work much more quickly than a work queues that subclasses WorkQueueBase.
