Marco Gaido created SPARK-22669:
-----------------------------------
Summary: Avoid unnecessary function calls in code generation
Key: SPARK-22669
URL: https://issues.apache.org/jira/browse/SPARK-22669
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.3.0
Reporter: Marco Gaido
In many parts of the codebase for code generation, we are splitting the code to
avoid exceptions due to the 64KB method size limit. This is generating a lot of
methods which are called every time, even though sometime this is not needed.
As pointed out here:
https://github.com/apache/spark/pull/19752#discussion_r153081547, this is a not
negligible overhead which can be avoided.
In this JIRA, I propose to use the same approach throughout all the other
cases, when possible. I am going to submit a PR soon.
