I think ProjectMergeRule related cyclic triggering has been walked around by
CALCITE-3774 [1].

I've seen it also quite a few times and most often the reason was cycles in
the subsets that were triggering some rules (e.g., ProjectMergeRule [1]) to
fire an infinite number of times [2, 3, 4].

Can you add a reproducible test case and log a JIRA? It may be different with
CALCITE-2057. People who is interested will investigate the issue.

Thanks
I didn't add any new rule, just these:
CONSTANT_REDUCTION_RULES
ABSTRACT_RELATIONAL_RULES
BASE_RULES
ABSTRACT_RULES
ENUMERABLE_RULES
So this is a bug, or it just because of the call stack is too deep(if this,
I can adjust JVM parameter).

I have had this happen numerous times when writing new planner rules. Most
of the time my rule is missing some boolean logic to prevent itself from
transforming the call. This results in the rule continuously transforming
it's previous transformations.
I can usually see this happening when I add
Hi
Has anyone encountered this problem before? Just a simple query(no more
than 20 lines, two joins, no union).
And I see this ticket: https://issues.apache.org/jira/browse/CALCITE-2057,
but there's no follow up, also I see flink may occur this problem(
