----------------------------------------------
Hi [~hhlai1990], can you explain a bit more what do you mean by saying that you
extended the native enumerable implemetantion.
Did you modify an existing Enumerable RelNode or did you add a new one? Are you
talking about adding a new adapter like calcite-pig, calcite-geode, etc?
> extend the native enummerable implemention of calcite to support Hive SQL

> [~julianhyde],
> 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.
