----------------------------------
Summary: Improve the performance of UnsafeProjection for wide table
Key: SPARK-17115
URL: https://issues.apache.org/jira/browse/SPARK-17115
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.0.0
Reporter: Davies Liu
Assignee: Davies Liu
We increase the threshold for splitting the generate code for expressions to
64K in 2.0 by accident (too optimistic), which could cause bad performance (the
huge method may not be JITed), we should decrease that to 16K.
