> Currently Kylin does not support non-equi join. This issue is aim to add runtime non-equi join feature to Kylin so that queries like
> {code:java}
>     select
>       |
>     non-equi join
>      /        \
>    subquery1  subquery2
> {code}
> can now be executed like below. Kylin will read data from subquery cubes and do non-equi join during runtime
> {code:java}
>     select
>       |
>     runtime non-equi join
>      /        \
>    cube1     cube2
> {code}
> I have submitted a PR for this issue
