Class RowGroupByteRangeFilterEvent

java.lang.Object

jdk.jfr.Event

dev.hardwood.jfr.RowGroupByteRangeFilterEvent

public class RowGroupByteRangeFilterEvent
extends Event

JFR event emitted when row groups are selected by a byte-range row-group predicate (split-aware reading).

This is distinct from RowGroupFilterEvent, which reports row groups dropped by statistics/bloom predicate push-down. Byte-range selection keeps a row group when its midpoint falls inside the requested split, and runs before push-down: the row groups reported as kept here are the input to the push-down evaluation.
