Apache Spark reassigned SPARK-27355:
------------------------------------
Assignee: (was: Apache Spark)
> make query execution more sensitive to epoch message late or lost
> -----------------------------------------------------------------
>
> Key: SPARK-27355
> URL: https://issues.apache.org/jira/browse/SPARK-27355
> Project: Spark
> Issue Type: Improvement
> Components: Structured Streaming
> Affects Versions: 3.0.0
> Reporter: Genmao Yu
> Priority: Minor
>
> In SPARK-23503, we enforce sequencing of committed epochs for Continuous
> Execution. In case a message for epoch n is lost and epoch (n + 1) is ready
> for commit before epoch n is, epoch (n + 1) will wait for epoch n to be
> committed first. With extreme condition, we will wait for
> `epochBacklogQueueSize` (10000 in default) epochs and then failed. There is
> no need to wait for such a long time before query fail, and we can make the
> condition more sensitive.
