---------------------------------
Issue Type: Wish (was: Improvement)
> Move functions to their own module and preprocess them at build time to
> speedup startup
> ---------------------------------------------------------------------------------------
>
> Key: DRILL-3717
> URL: https://issues.apache.org/jira/browse/DRILL-3717
> Project: Apache Drill
> Issue Type: Wish
> Components: Execution - Codegen
> Reporter: Julien Le Dem
> Assignee: Chris Westin
>
> all the functions included in the drill distirbution are scanned in the
> classpath and then parsed with janino at startup.
> This slows down startup and unit tests.
> If they were in their own module it would be possible to preprocess at build
> time and have a much better startup time, including in tests.
> The classpath scanning library used (reflections) already has a mechanism to
> persist its result.
