Description

To repro -

1. Set Log4J log level to TRACE. So planner will dump rel node info every time at rule match (https://github.com/apache/calcite/blob/3124a85b93ff2f1b79484c7bd4cc41835d4f1920/core/src/main/java/org/apache/calcite/plan/volcano/RuleQueue.java#L435)

2. Run JdbcTest.testNotExistsCorrelated. Get below exception -

java.lang.AssertionError: rel [rel#63:EnumerableAggregate.ENUMERABLE.[](input=RelSubset#62,group=

{0}

)] has lower cost

{131.0 rows, 216.0 cpu, 0.0 io}

than best cost

{131.5 rows, 216.0 cpu, 0.0 io}

of subset rel#60:Subset#4.ENUMERABLE.[]
