[jira] [Created] (KYLIN-4480) Implement runtime non-equi join

Li Xian created KYLIN-4480:
------------------------------

             Summary: Implement runtime non-equi join
                 Key: KYLIN-4480
                 URL: https://issues.apache.org/jira/browse/KYLIN-4480
             Project: Kylin
          Issue Type: New Feature
          Components: Query Engine
            Reporter: Li Xian


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
