-------------------------------------
Summary: Create a sys.functions table to expose available Drill
functions
Key: DRILL-3988
URL: https://issues.apache.org/jira/browse/DRILL-3988
Project: Apache Drill
Issue Type: Improvement
Components: Metadata
Reporter: Jacques Nadeau
Create a new sys.functions table that returns a list of all available functions.
Key considerations:
- one row per name or one per argument set. I'm inclined to latter so people
can use queries to get to data.
- we need to create a delineation between user functions and internal functions
and only show user functions. 'CastInt' isn't something the user should be able
to see (or run).
- should we add a description annotation that could be included in the
sys.functions table?
