[jira] [Created] (FLINK-37481) Multi way join operator

Gustavo de Morais created FLINK-37481:
-----------------------------------------

             Summary: Multi way join operator
                 Key: FLINK-37481
                 URL: https://issues.apache.org/jira/browse/FLINK-37481
             Project: Flink
          Issue Type: New Feature
            Reporter: Gustavo de Morais


We currently always rely on a chain of binary joins when there are multiple joins in a query. There are optimizations that can be done to a multi way join operator that can optimize the worst case scenarios for binary joins.

 

We want as a first step with this ticket to have a multi join operator that works on multiple inputs.
