[GitHub] [incubator-pinot] Jackie-Jiang opened a new issue #6081: Optimize the performance of DISTINCT queries
Jackie-Jiang opened a new issue #6081:
URL: https://github.com/apache/incubator-pinot/issues/6081
Opportunities:
1. Separate DISTINCT from aggregation and make it a standalone type of query (similar to select but deduplicate the records) so that early termination logic can be easily plugged in
2. Specialize order-by with 1 column, where we can directly work on primitive type
