> Early optimization for adaptive join when one input is below broadcast
> threshold
> --------------------------------------------------------------------------------
>
> Key: FLINK-37382
> URL: https://issues.apache.org/jira/browse/FLINK-37382
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 2.0.0
> Reporter: xingbe
> Assignee: xingbe
> Priority: Major
>
> When the large table side has not yet initialized, if the small table side
> finishes early and the output data volume is smaller than the broadcast
> threshold, the adaptive join operator can be optimized to a broadcast hash
> join in advance. This can help reduce network shuffle overhead.
