Summary: Port Phoenix star-join to Phoenix/Calcite integration (was: Port
Phoenix star-join to Calcite integration)

> Key: PHOENIX-1787
> URL: https://issues.apache.org/jira/browse/PHOENIX-1787
> Project: Phoenix
> Issue Type: Sub-task
> Reporter: Maryann Xue
> Original Estimate: 480h
> Remaining Estimate: 480h
>
> Enable parallel hash-join of multiple tables. For example A join B join C,
> instead of joining two tables at a time, we can probably probe A and join
> built B and built C at the same time if memory is allowed.
> We can make use of Calcite Multijoin and enable Multijoin related rules. If
> we find out that a star-join is not doable due to (right) outer joins or
> memory limit, we can set the cost to infinite and thus discard this
> optimization.
