> Resourceutils.renameResource uses Iterator.remove() to make changes. TDB does not support Iterator.remove 
> Instead, renameResource could grab a block (say, 1000) items, rename them and loop on blocks of 1000.  This way, the iterator is terminated before updates are done.  The nature of the rename operation means that the find iterator is executed until no resources are found so this batching mechanism does not need to need to track what has and has not been found - just repeat until less than 1000 items found.
