Jackie-Jiang opened a new pull request #5686: URL: https://github.com/apache/incubator-pinot/pull/5686
Split `CombineOperator` into 3 different combine operators: - `SelectionOnlyCombineOperator` - `SelectionOrderByCombineOperator` - `AggregationOnlyOrderByCombineOperator` (For aggregation-group by, rename the combine operator to `GroupByCombineOperator` and `GroupByOrderByCombineOperator`) For `SelectionOnlyCombineOperator`: - Only process 1 segment for `LIMIT 0` - Early termination when enough rows are collected For `SelectionOrderByCombineOperator`: - If the first order-by expression is an identifier (column), sort segments by the column min/max value and early terminate when result for the segment must not be in the final result. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
