jt-kloudfuse opened a new pull request #8228: URL: https://github.com/apache/pinot/pull/8228
## Description <!-- Add a description of your PR here. For a query like, Order by col1, col2 limit k will take all the n matching rows and add it to a priority queue of size k. This is nlogk operation which can be quite expensive for a large n. In the above example, if the docs are already sorted by col1, col2 then there is no need for any sorting at all (only limit is needed). This PR basically tracks if left most columns are sorted and if they all are, then short circuits the nlogk loop. --> ## Upgrade Notes Does this PR prevent a zero down-time upgrade? (Assume upgrade order: Controller, Broker, Server, Minion) * [ No] Does this PR fix a zero-downtime upgrade introduced earlier? * [ No] Does this PR otherwise need attention when creating release notes? Things to consider: - New configuration options - Deprecation of configurations - Signature changes to public methods/interfaces - New plugins added or old plugins removed * [ No] ## Release Notes <!-- If you have tagged this as either backward-incompat or release-notes, you MUST add text here that you would like to see appear in release notes of the next release. --> <!-- If you have a series of commits adding or enabling a feature, then add this section only in final commit that marks the feature completed. Refer to earlier release notes to see examples of text. --> ## Documentation <!-- If you have introduced a new feature or configuration, please add it to the documentation as well.
