> InferFiltersFromConstraint and PropagateEmptyRelation rules are added as part
> of Optimization rules
> --------------------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-55241
> URL: https://issues.apache.org/jira/browse/SPARK-55241
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 4.2.0, 4.1.1
> Reporter: Asif
> Priority: Major
> Labels: pull-request-available
>
> To fix issues SPARK-55185 and SPARK-55072, PropagateEmptyRelations and
> InferFiltersFromConstraints rules need to be added to the Operator
> Optimizations Batch rules, which run for Fixed Iterations.
> But addition of these 2 rules break the idempotency of SPARK SQL Streaming
> in certain cases.
> The issue is that in PropagateEmptyRelation, the Join case is transformation
> is skipped ( rightly so , for streaming case), but the Filter case
> transformation is allowed.
> Ideally the Filter case transformation should also be suppressed for
> Streaming case, IMO.
