-----------------------------------
Summary: Improve always-true min/max filter handling in coordinator
Key: IMPALA-10647
URL: https://issues.apache.org/jira/browse/IMPALA-10647
Project: IMPALA
Issue Type: Improvement
Reporter: Qifan Chen
Currently, when a justarriving min/max filter is the last one to arrive or is
always true, the coordinator disables the corresponding filter
representation by setting it to Always True. This makes it
impossible to differentiate a true AlwaysTrue filter (say, set in the
hash join building step) from the one being disabled.
A better handling is needed in this area.
