Tim Armstrong created IMPALA-9255: ------------------------------------- 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
