Summary: 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
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.
