---------------------------------

             Summary: Avoid memory copy from direct buffer to heap while spilling to local
disk
                 Key: DRILL-6002
                 URL: https://issues.apache.org/jira/browse/DRILL-6002
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Vlad Rozov
            Assignee: Vlad Rozov


When spilling to a local disk or to any file system that supports WritableByteChannel it is
preferable to avoid copy from off-heap to java heap as WritableByteChannel can work directly
with the off-heap memory.
