-----------------------------------
This proposal make sense to me, do you have any detail design docs?
> 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
> Priority: Major
>
> 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.
