------------------------------------
Assignee: Xiening Dai
> Add rule listener to report rule attempts and time at DEBUG log level
> ---------------------------------------------------------------------
>
> Key: CALCITE-3915
> URL: https://issues.apache.org/jira/browse/CALCITE-3915
> Project: Calcite
> Issue Type: Bug
> Reporter: Xiening Dai
> Assignee: Xiening Dai
> Priority: Minor
>
> We can add a rule listener to the VolcanoPlanner for recording rule attempts
> and the accumulative time for the rule firing. This would be very helpful to
> debug planner performance issue (such as CALCITE-2970). The listener will
> only be added under DEBUG log level.
> It will produce a rule attempt summary like below -
> {noformat}
