Laljo John Pullokkaran commented on HIVE-11918:
-----------------------------------------------
We have to go through the upgrade to 1.5 anyway. But its probably going to be
1.5 - 2 months away.
Could we get the work around instead?
> Implement/Enable constant related optimization rules in Calcite

> 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.
