Subject [jira] [Updated] (HIVE-11918) Implement/Enable constant related optimization rules in Calcite
Date Tue, 22 Sep 2015 20:22:04 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11918?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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 short
of the constant related optimization rules. For example, constant folding, constant propagation
and constant transitive rules. This JIRA is the umbrella JIRA to implement/enable those rules.)
