Hey folks- I'm curious if anyone has thoughts around idempotency concerns related to the LeafCollector#finish API added in GH#12380 <https://github.com/apache/lucene/pull/12380>. My expectation would be that LeafCollector implementations should be able to assume #finish will only get called once. In fact, it looks like FacetsCollector is already making that assumption.
Is this inline with other folks' expectations? If so, I'm going to, 1) address a small bug related to drill-sideways that results #finish being called multiple times on one of the collectors, and 2) propose some additional javadoc on LeafCollector#finish clarifying this. Make sense? Cheers, -Greg
