-------------------------------------
Summary: Large allocations are not released until GC kicks in
Key: DRILL-2940
URL: https://issues.apache.org/jira/browse/DRILL-2940
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Reporter: Jacques Nadeau
Assignee: Jacques Nadeau
If you allocate over the chunk size (16mb), we are currently relying on GC to
release those buffers. This is problematic since direct memory pressure doesn't
cause gc. In some situations with fast memory turnover, this means we run out
of memory incorrectly.
