    Description

      When there are ~50 files being committed; each in their own thread from the commit pool; probably the DDB repo is being overloaded just from one single process doing task commit. We should be backing off more, especially given that failing on a write could potentially leave the store inconsistent with the FS (renames, etc)

      It would be nice to have some tests to prove that the I/O thresholds are the reason for unprocessed items in DynamoDB metadata store
