Interface Summary

Interface	Description
DataSourceFilter	A function which filters based on a data source constraint.
PhysicalTableMatcher	Function to test whether a Physical Table can satisfy a criteria for a request.

Class Summary

Class	Description
AggregatableDimensionsMatcher	Use the granularity and columns of a query to determine whether or not tables can satisfy this query.
BasePhysicalTableResolver	Abstract parent to with business rule agnostic implementations of core methods.
DataSourceConstraint	Constraints for retrieving potential table availability for a given query.
DefaultPhysicalTableResolver	A physical table resolver which implements core bard filters and comparator functions
DimensionCardinalityComparator	Comparator to prefer fewer dimensions in physical tables (for the purpose of preferring fewer rows).
DimensionIdFilter	An implementation of DataSourceFilter which uses dimensionApiFilters to match partition data sources.
GranularityComparator	Comparator to prefer coarser physical tables (i.e.
PartialTimeComparator	Comparator to prefer less partial data duration within the query.
PhysicalDataSourceConstraint	Data source constraint containing physical name of the columns.
QueryPlanningConstraint	Constraints used to match and resolve the best table for a given query.
RequestQueryGranularityResolver	A function to take an ApiRequest and TemplateDruidQuery and determine a Granularity which must be satisfied by a fact source in order to satisfy this request.
SchemaPhysicalTableMatcher	Use the granularity and columns of a query to determine whether or not tables can satisfy this query.
TimeAlignmentPhysicalTableMatcher	Tests whether a physical table aligns with the request time and period.
VolatileTimeComparator	Comparator that prefers tables that contain more data in volatile requested intervals.
