I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Support un-ordered mode for async lookup join
> ---------------------------------------------
>
> Key: FLINK-16332
> URL: https://issues.apache.org/jira/browse/FLINK-16332
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / Runtime
> Reporter: Jark Wu
> Priority: Major
> Labels: stale-major
>
> Currently, we only support "ordered" mode for async lookup join. Because the
> ordering in streaming SQL is very important, the accumulate and retract
> messages shoudl be in ordered. If messages are out of order, the result will
> be wrong.
> The "un-ordered" mode can be enabled by a job configuration. But it will be a
> prefered option. Only if it doesn't affect the order of acc/retract messages
> (e.g. it is just an append-only stream), the "un-ordered" mode will be
> enabled.
