------------------------------------
Summary: Detect ordered/unordered group-by
Key: PHOENIX-1837
URL: https://issues.apache.org/jira/browse/PHOENIX-1837
Project: Phoenix
Issue Type: Sub-task
Reporter: Maryann Xue
Assignee: Maryann Xue
With ordered group-by, we would do much less work. The existing Phoenix code
depends on TrackOrderPreservingExpressionCompiler to calculate the flag. But
given that we would no longer use any of the Phoenix parse tree nodes and the
TrackOrderPreservingExpressionCompiler is a parse tree node visitor, we should
now implement the same logic with Calcite RexNode.
