[jira] [Updated] (KYLIN-993) implement substr support in kylin

     [ https://issues.apache.org/jira/browse/KYLIN-993?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dong Li updated KYLIN-993:
--------------------------
    Attachment: 0001-KYLIN-993-Support-functions-in-where-clause.patch

This patch will translate parts of single-col filter function to IN clause, like LOWER/UPPER/SUBSTRING/LIKE/INCAP, and pass others to calcite for in-memory filter.
Patch is for 1.x, please help to review. I'll port to 2.x and enable more translation if it's OK.
