Interface IndexProperties

All Known Implementing Classes:
IndexSelector.DrillIndexProperties
public interface IndexProperties
IndexProperties encapsulates the various metrics of a single index that are related to the current query. These metrics are subsequently used to rank the index in comparison with other indexes.
