WorkManager that supports distributed
execution of Work instances.
A DistributableWorkManager may choose to distribute a
Work instance submitted by a resource adapter to another
WorkManager instance running in a different Java virtual machine
(that is running in the same host or different hosts) for achieving optimal
resource utilization or for providing better response times.
A WorkManager implementation that supports the submission of
DistributableWork instances must implement the
DistributableWorkManager marker interface.
