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.
