Description

Currently, Kylin cache part for RDBMS has poor performance while load many tables with sql-case-sensitive,it will take much time to load database,table,column identifier to cache in order to fix sql-case-sensitive problem for RDBMS.I found it has space to imporve .So I'd like to  contribute a patch.
