Interface Summary

Interface	Description
AggregationContextFactory	Produces an AggregationContext for aggregations given a table and the names of the group by columns.
AggregationContextTransformer	Transformer to adjust aggregation results for operation building.
AggregationMemoKey	Marker interface for AggregationStates to use for memoization keys.
AggregationStateFactory	The aggregation state factory is passed to the by operation, and is used to create new aggregation states for each of the output rows (or in case of byExternal, each of the output tables).
ByExternalChunkedOperator.AttributeCopier
ComboAggregateFactory.ComboBy
IterativeChunkedAggregationOperator	A chunked, iterative operator that processes indices and/or data from one input column to produce one or more output columns.
IterativeChunkedAggregationOperator.BucketedContext	Context interface for bucketed operator updates.
IterativeChunkedAggregationOperator.SingletonContext	Context interface for singleton (that is, one aggregation state) operator updates.
IterativeChunkedOperatorFactory
ReaggregationIterativeOperator<T,STATE>
