----------------------------------
Summary: Rollup of External Sort memory management fixes
Key: DRILL-5601
URL: https://issues.apache.org/jira/browse/DRILL-5601
Project: Apache Drill
Issue Type: Task
Affects Versions: 1.11.0
Reporter: Paul Rogers
Assignee: Paul Rogers
Fix For: 1.11.0
Rollup of a set of specific JIRA entries that all relate to the very difficult
problem of managing memory within Drill in order for the external sort to stay
within a memory budget. In general, the fixes relate to better estimating
memory used by the three ways that Drill allocates vector memory (see
DRILL-5522) and to predicting the size of vectors that the sort will create, to
avoid repeated realloc-copy cycles (see DRILL-5594).
