Stamatis Zampetakis commented on CALCITE-2741:
----------------------------------------------

[~hhlai1990], possibly you can introduce some new field(s) in 
RexToLixTranslator to hold there such information. Alternatively, you can have 
a look at the @Deterministic annotation (see 
org.apache.calcite.runtime.RandomFunction for an example).

 

> Add operator table with Hive-specific built-in functions

> I extended the native enummerable implemention of calcite to support Hive sql 
> ,include UDF、UDAF and all the SqlSpecialOperator,which inspired by apache 
> Drills.
> I modified the parser,type systems,and bridge the hive operator .
> How do you think of supporting a direct implemention of hive sql like this?
> I think it will be valueable when someone want to migrate his hive etl jobs 
> to real-time scene.
