>                 URL: https://issues.apache.org/jira/browse/PHOENIX-943
>             Project: Phoenix
>          Issue Type: Sub-task
>    Affects Versions: 3.0.0, 4.0.0, 5.0.0
>            Reporter: Maryann Xue
>            Assignee: Maryann Xue
>            Priority: Minor
>             Fix For: 3.0.0, 4.0.0, 5.0.0

>   Original Estimate: 48h
>  Remaining Estimate: 48h

> Support cases like:
> 1) select ... from A join (select id, b from T limit 10) as B on A.id = B.id where B.b = 'b'
> 2) select ... from A join (select count(*) c from T) as B on A.a = B.c where B.c > 10
> These 2 cases cannot be handled by SubselectRewriter#applyPostFilters(), thus JoinCompiler should compile post-filters into query-plans for subqueries.
