Jark Wu updated FLINK-19830:
----------------------------
Component/s: Table SQL / Runtime
> Properly implements processing-time temporal table join
> -------------------------------------------------------
>
> Key: FLINK-19830
> URL: https://issues.apache.org/jira/browse/FLINK-19830
> Project: Flink
> Issue Type: Sub-task
> Components: Table SQL / Runtime
> Reporter: Leonard Xu
> Priority: Major
>
> The exsiting TemporalProcessTimeJoinOperator has already supported temporal
> table join.
> However, the semantic of this implementation is problematic, because the join
> processing for left stream doesn't wait for the complete snapshot of temporal
> table, this may mislead users in production environment.
> Under the processing time temporal join semantics, to get the complete
> snapshot of temporal table may need introduce new mechanism in FLINK SQL in
> the future.
