> Add OuterJoin strategy with HashTable on outer side
> ---------------------------------------------------
>
> Key: FLINK-2871
> URL: https://issues.apache.org/jira/browse/FLINK-2871
> Project: Flink
> Issue Type: New Feature
> Components: Local Runtime, Optimizer
> Affects Versions: 0.10.0
> Reporter: Fabian Hueske
> Assignee: Chengxiang Li
> Priority: Minor
>
> Outer joins are currently supported with two local execution strategies:
> - sort-merge join
> - hash join where the hash table is built on the inner side. Hence, this
> strategy is only supported for left and right outer joins.
> In order to support hash-tables on the outer side, we need a special hash
> table implementation that gives access to all records which have not been
> accessed during the probe phase.
