PR [https://github.com/apache/arrow/pull/11019] implements SelectKUnstable. Some previous result of SelectKUnstable using StableHeap is shown here: [https://github.com/apache/arrow/pull/11019#issuecomment-913977337] So, implementation of SelectKStable should explore how to implement this algorithm using StablePartition + stable_sorting. -- This message was sent by Atlassian Jira (v8.3.4#803005)
