Pengcheng Xiong updated HIVE-11918:
-----------------------------------
Description: Right now, Hive optimizer (Calcite) is short of the constant
related optimization rules. For example, constant folding, constant propagation
and constant transitive rules. Although Hive later provides those rules in the
logical optimizer, we would like to implement those inside Calcite. This will
benefit the current optimization as well as the optimization based on return
path that we are planning to use in the future. This JIRA is the umbrella JIRA
to implement/enable those rules. (was: Right now, Hive optimizer (Calcite) is
