--------------------------------------
Summary: Large compilation unit tests fails due to high memory
allocation
Key: DRILL-1808
URL: https://issues.apache.org/jira/browse/DRILL-1808
Project: Apache Drill
Issue Type: Bug
Reporter: Steven Phillips
The buildSchema method of external sort calls allocateNew() on each vector in
schema batch, which normally isn't much memory, but when there are thousands of
columns, this ends up being significant. We should avoid allocating any memory
for the schema batch.
