Lou DeGenaro resolved UIMA-4341.
--------------------------------
Resolution: Fixed
Code delivered.
JD now keeps a map of work items comprising status changes which is written to
disk during OR publication receipt processing.
A work item is added/updated in the map when its status changes and is removed
upon writing its status to disk.
Previously, each work item status change was immediately written to disk. For
Jobs with large numbers of work items this soon became a performance bottleneck.
> DUCC Job Driver (JD) should not piggyback writing of work item state on
> Get/Ack requests
