scottlan0113 opened a new issue, #19388:
URL: https://github.com/apache/pinot/issues/19388
Follow-up to #10498 — the sharded off-heap GROUP BY table prototype
("Direction C") is now recommended after comparing it against two alternatives
on correctness, performance, and memory, and has since had multi-column keys,
non-additive aggregates (MIN/MAX), and several bug fixes added, all
correctness- and JMH-verified.
Design doc for the next step — wiring it into `GroupByCombineOperator`:
