…gated data (apache#17058) changes: * CursorHolder.isPreAggregated method indicates that a cursor has pre-aggregated data for all AggregatorFactory specified in a CursorBuildSpec. If true, engines should rewrite the query to use AggregatorFactory.getCombiningAggreggator, and column selector factories will provide selectors with the aggregator interediate type for the aggregator factory name * Added groupby, timeseries, and topN support for CursorHolder.isPreAggregated * Added synthetic test since no CursorHolder implementations support isPreAggregated at this point in time
