             Summary: Retention Job should be more robust to OOM failures
                 Key: GOBBLIN-2006
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-2006
             Project: Apache Gobblin
          Issue Type: Bug
          Components: misc
            Reporter: Arpit Varshney


Currently, while cleaning the log files, the Retention job goes into OOM and 
fails when the no of log files is too many. 
Retention while fetching all the dataset versions, loads the file status all at 
once into the memory, resulting in this issue. 
Thus, the Retention job should avoid loading all data into memory, and use an 
iterator-based approach. This will load only limited file status into memory 
and making the retention job pipeline more robust.
