Asif created SPARK-55241:
----------------------------
Summary: Idempotency of SQL Streaming involving Joins is broken if
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: 4.1.1, 4.2.0
Reporter: Asif
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.
