-------------------------------------
Summary: Take plan dependencies into account for resource
consumption
Key: IMPALA-9255
URL: https://issues.apache.org/jira/browse/IMPALA-9255
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Reporter: Tim Armstrong
In Planner.computeResourceReqs(), we assume that all fragment's peak resource
consumption occurs at the same time. In actually, with the separate join build,
there are dependencies between fragments and we could take those into account
to reduce the estimated resource requirements.
