-----------------------------------
Summary: ensure all allocators for a query are descendants of a
single root
Key: DRILL-2421
URL: https://issues.apache.org/jira/browse/DRILL-2421
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Reporter: Chris Westin
Assignee: Chris Westin
Fix For: 0.9.0
In order to help improve usage tracking, allocations for a single query should
all roll up to a single root.
This requires that the Foreman create that root, and label it, and then pass
that along to anyone else that needs to create additional sub-allocators. The
patch for DRILL-2406 introduces the creation of a new allocator in
QueryContext, but this is currently a child of the Drillbit's
TopLevelAllocator, violating the principle above. This is a reminder to fix
that after the dependencies above are available.
