------------------------------------------------------------
hi,[~julianhyde] , [~zabetak],[~zhztheplayer], [~hyuan],[~francischuang]
I create a new adapter of Calcite that support hive sql queries on dataset.
Since the extensions is made base on Calcite 1.18.0, I pushed the project to a
new codebase: [https://github.com/51nb/marble]
And I proposed a Table API to make it easy to execute a sql query.
We use it in our company's core financial business to unify the way to compute
lots of model variables .
This project shows how we extend Calcite core to support hive sql queries, it
may be helpful to people
who wants to build a customized sql engine on top of Calcite.

> Reporter: Lai Zhou
> Priority: Minor
>
> [~julianhyde],
> I write a hive adapter for calcite to support Hive sql ,includes
> UDF、UDAF、UDTF and some of SqlSpecialOperator.
> 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.
