------------------------------------------
Summary: Improve RuleEventLogger to also print input rels in FULL_PLAN mode
(was: Improve RuleLogger to also print input rels in FULL_PLAN mode)
> Improve RuleEventLogger to also print input rels in FULL_PLAN mode
> ------------------------------------------------------------------
>
> Key: CALCITE-4991
> URL: https://issues.apache.org/jira/browse/CALCITE-4991
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.29.0
> Reporter: Alessandro Solimando
> Assignee: Alessandro Solimando
> Priority: Major
>
> After using for some time now the new plan logging capabilities introduced
> via _RuleEventLogger_ in CALCITE-4704, only printing the new rel produced by
> a rule is not enough for complex cases, because the input rel(s) used by the
> rule are not printed, and sometimes they are nowhere in the logs, making it
> hard to understand what situation caused the appearance of a given plan of
> interest.
> The present ticket aims at additionally printing, for _FULL_PLAN_ marker, the
> input rels used by a given rule, before printing the output rel produced by
> the rule application.
> The output logs would evolve from:
> {noformat}
