--------------------------------------
Summary: Avoid or codegen std::map comparisons in partitioned top-n
Key: IMPALA-10228
URL: https://issues.apache.org/jira/browse/IMPALA-10228
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Tim Armstrong
The partitioned top-n implementation currently uses std::map to store the
heaps. We can't inline the tuple comparator easily because of the indirections
in the standard library code.
