Hi,

REBUILD DATAMAP is implemented only for the full refresh, not done for
incremental data loading, that's why it tries to refresh all the segments
irrespective of it is already built or not.  We are planning for the
incremental rebuilding of datamap in the next version.  
I feel we can block creating datamap with deferred rebuild and rebuilding of
datamap for index datamaps in current code as we generate index online while
doing the loading of data. We can unblock the rebuild feature for index
datamap after we finish the incremental rebuilding of datamap framework.
