[jira] [Created] (IMPALA-8318) Consider more advance I/O resource management

Tim Armstrong created IMPALA-8318:
-------------------------------------

             Summary: Consider more advance I/O resource management
                 Key: IMPALA-8318
                 URL: https://issues.apache.org/jira/browse/IMPALA-8318
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Tim Armstrong


This is a placeholder for more sophisticated policies. We currently do a kind of round-robin between scans that provides a kind of fairness. But we could do a lot more, e.g. allocate different shares to different queries, factor in I/O size rather than just I/O ops, etc.
