>             Project: Kylin
>          Issue Type: New Feature
>          Components: Query Engine
>    Affects Versions: v4.0.0-alpha
>            Reporter: ShengJun Zheng
>            Assignee: ShengJun Zheng
>            Priority: Major
>             Fix For: v4.0.0-GA

> when use top-level result offset clause in query expression (ANSI SQL) :  
> limit xxx offset xxx in spark query engine,limit will not push down into 
> spark engine, and offset will not take effect. This is incompatible wIth 
> Kylin 2.x~3.x.
> After looking through the code, i found it's because spark dose not support 
> limit ... offset ... now. There is a spark issue in progress: 
> https://issues.apache.org/jira/browse/SPARK-28330, which was created in 2019 
> but still in progress.
> So, should we support this feature temporarily in KYLIN? :
>    1. push down limit to spark
>    2. take result from starting offset  in KYLIN query server
>
