> 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.
