Shuyi Chen commented on CALCITE-2046:
-------------------------------------
I think we need another Jira [CREATE
FUNCTION|https://my.vertica.com/docs/7.2.x/HTML/index.htm#Authoring/SQLReferenceManual/Statements/CREATEFUNCTIONUDF.htm]
support.
Also, to load external libraries for code generation when compiling, do you
have any suggestions? I look through the documentation and code, the only
solution I can find is to use the ICookable.setParentClassLoader to replace the
classloader with another one that has the external libraries loaded. I'll
appreciate your insight.
