public class RowGroupDictionaryFilterEvent extends Event

JFR event emitted when a row group's dictionaries prove that none of its rows matches the filter, once the read reaches the row group.

RowGroupFilterEvent reports the decisions statistics take for all row groups of a file before it is read, and counts a row group dropped here as kept. A row group its bloom filters drop is reported by RowGroupBloomFilterEvent and reaches no dictionary.
